The HTP test’s admissibility hinges on its application; generating hypotheses for stronger instruments is accepted, especially with children or those with language impairments.
It’s a useful tool for uncovering lines of questioning, though findings require confirmation via other methods, as interpretations can be ambiguous and context-dependent.
What is the House-Tree-Person Test?
The House-Tree-Person (HTP) test is a projective psychological test where individuals are asked to draw a house, a tree, and a person. It’s not a standardized test with ‘right’ or ‘wrong’ answers; instead, it aims to reveal underlying personality characteristics, emotional states, and cognitive processes through the analysis of the drawings.
The test operates on the principle that individuals project their inner world – thoughts, feelings, and experiences – onto ambiguous stimuli, in this case, the simple prompts of drawing common objects. Interpretations aren’t based on artistic skill, but rather on elements like size, shape, placement on the page, details included or omitted, and the overall organization of the drawing.
While not a definitive diagnostic tool on its own, the HTP can offer valuable insights, particularly when used alongside other assessment methods. It’s often employed in clinical settings to aid in understanding a client’s psychological functioning, especially with individuals who may have difficulty expressing themselves verbally, like children or those with communication challenges.

Historical Context of the HTP Test
The House-Tree-Person test emerged from the broader development of projective testing in the mid-20th century, heavily influenced by the work of psychoanalysts like Sigmund Freud and Carl Jung. While not directly created by either, the HTP built upon their theories of personality and the unconscious mind, aiming to access hidden aspects of an individual’s psyche.
Virginia Axline is generally credited with developing the HTP as a clinical tool in the 1940s, initially using it with children in play therapy. She observed that children’s drawings often reflected their emotional experiences and family dynamics. The test gained popularity as clinicians recognized its potential for understanding individuals who struggled with verbal expression.
Over time, various scoring systems and interpretive frameworks were developed, though none have achieved universal acceptance. The HTP’s history reflects a shift towards more qualitative and interpretive approaches in psychological assessment, moving beyond purely quantitative measures. Its continued use demonstrates its enduring appeal as a means of exploring the complexities of human personality.
Purpose of the HTP Test in Psychological Assessment
The House-Tree-Person (HTP) test serves as a projective psychological assessment tool designed to evaluate an individual’s personality, emotional state, and underlying cognitive processes. It’s particularly useful when working with individuals who have difficulty expressing themselves verbally, such as children or those with language impairments.
Unlike direct questioning, the HTP aims to elicit responses from the unconscious, revealing hidden feelings, conflicts, and perceptions. Clinicians use the drawings to gain insights into self-concept, interpersonal relationships, and overall psychological functioning. It’s not a diagnostic tool in itself, but rather a means of generating hypotheses for further investigation.
The HTP can help identify areas of emotional distress, assess coping mechanisms, and understand an individual’s worldview. Importantly, interpretations must be made cautiously, considering the context and utilizing additional assessment methods for validation. It’s best employed as part of a comprehensive psychological evaluation.

Administering the HTP Test
Proper administration requires standardized instructions, a quiet setting, and basic materials like paper and drawing tools. Careful observation during the process is also crucial.
Standardized Instructions for Test Administration
Begin by establishing rapport with the individual, ensuring they understand the task isn’t about artistic skill, but rather expressing their perceptions. Present each stimulus – house, tree, and person – individually, with a clear, consistent prompt: “Draw a house as best you can.” Repeat this phrasing for the tree and then the person.
Crucially, offer no further elaboration or guidance beyond this initial instruction. Avoid prompting for details or suggesting elements to include. Allow ample time for each drawing, typically around 15-20 minutes per image, observing for any hesitation or unusual behaviors. Maintain a neutral demeanor, refraining from any commentary or judgment during the drawing process.
Ensure the order is consistent – house first, then tree, and finally the person – for all participants. After each drawing is completed, simply proceed to the next stimulus. Record any spontaneous comments made by the individual, but do not initiate conversation about the drawings until after all three are finished. This standardized approach minimizes bias and maximizes the reliability of the projective data.
Materials Required for the HTP Test
The core materials for administering the House-Tree-Person (HTP) test are remarkably simple, prioritizing a neutral and non-directive environment. You will need three sheets of unlined white paper, ideally 8.5 x 11 inches in size, to accommodate each drawing. Standard graphite pencils – typically a #2 pencil – are essential; avoid colored pencils, crayons, or markers, as these introduce unnecessary variables and potential for symbolic interpretation beyond the core projective elements.
An eraser is also necessary, allowing the individual to make corrections without feeling constrained. A comfortable, flat surface for drawing is crucial, along with adequate lighting to ensure clear visibility. A recording sheet or notebook is needed to document any spontaneous verbalizations made during the test, as well as observational notes regarding the individual’s behavior and approach to the task. Finally, a quiet and private testing environment is paramount, minimizing distractions and fostering a sense of security.
Setting and Environment for Optimal Results
Creating a conducive environment is paramount for obtaining reliable results from the House-Tree-Person (HTP) test. The testing space should be quiet, private, and free from distractions – minimizing interruptions from noise, other people, or visual stimuli. A comfortable room temperature and adequate lighting are essential to ensure the individual feels at ease and can focus on the task.
The atmosphere should be non-threatening and neutral; the examiner should maintain a passive and accepting demeanor, avoiding any leading questions or interpretations during the drawing process. It’s crucial to establish rapport and convey a sense of safety, encouraging the individual to express themselves freely without fear of judgment. A clean and uncluttered workspace is also recommended, further reducing potential distractions and promoting a sense of calm. The goal is to facilitate spontaneous expression, allowing the drawings to reflect the individual’s inner world with minimal external influence.

Drawing the House
Instruct the participant to draw a house, a tree, and a person, each on separate sheets. Encourage them to draw whatever comes to mind, without striving for artistic perfection.
Instructions for Drawing the House
Begin by stating, “I would like you to draw a house, a tree, and a person. Draw each on a separate sheet of paper. Take your time and draw whatever comes to mind. There are no right or wrong answers; just draw what feels natural to you.” Emphasize that artistic skill isn’t important – the focus is on what they choose to depict.
Specifically for the house, avoid leading questions; Simply request, “Now, please draw a house.” Allow the individual complete freedom in their representation. Do not specify the type of house (e.g., cottage, mansion) or any details. Observe if they ask for clarification; their questions can be insightful.
Ensure they understand each drawing is independent. Avoid phrases like “Now draw a house with a tree.” The separation is crucial for individual projections. Maintain a neutral demeanor throughout, offering only the basic instruction and avoiding any commentary or encouragement during the drawing process. This minimizes influence on their responses.
Record the order in which they complete the drawings, as this can also be a relevant observation. Note any spontaneous comments made before, during, or after the drawing, as these provide valuable contextual information.
Common Interpretations of House Characteristics
A large, detailed house often suggests a strong self-esteem and a positive self-image, potentially indicating a secure and well-structured inner world. Conversely, a small or poorly defined house might reflect feelings of inadequacy or insecurity.
The roof’s prominence signifies the individual’s thoughts and fantasies; a large, emphasized roof could indicate a rich inner life, while a missing or poorly drawn roof may suggest feeling overwhelmed or lacking direction. Walls represent the individual’s defenses; strong, solid walls suggest effective boundaries, while weak or broken walls indicate vulnerability.
Doors symbolize openness to the outside world; a large, welcoming door suggests sociability, while a small, hidden, or absent door may indicate withdrawal or difficulty connecting with others. Windows represent how the individual views the world; many windows suggest openness and curiosity, while few or small windows may indicate guardedness.
However, these are general tendencies. Context is vital; a simple drawing style doesn’t automatically equate to pathology, and interpretations must consider the entire picture.
Symbolism in House Drawings: Roof, Walls, Doors, Windows
The roof, representing thoughts and fantasies, is a key indicator. An exceptionally large or ornate roof can signify a vivid imagination, potentially bordering on escapism, while a flat or missing roof may suggest a feeling of being exposed or lacking intellectual stimulation.
Walls symbolize the individual’s defenses and boundaries. Thick, strong walls often denote a well-defined sense of self and effective coping mechanisms. Conversely, thin, broken, or absent walls can indicate vulnerability, permeability, or difficulty maintaining personal boundaries.
Doors represent openness to experience and interaction with the external world. A large, central door suggests sociability and accessibility, while a small, hidden, or absent door may reflect withdrawal, isolation, or difficulty forming relationships.
Windows symbolize the individual’s perspective and how they allow others to see them. Numerous windows suggest openness and curiosity, while few or small windows may indicate guardedness or a desire for privacy. Remember, these are symbolic representations needing careful contextualization.

Drawing the Tree
Tree depictions reveal aspects of personal growth, stability, and connection to roots. Analyzing branches, leaves, the trunk, and roots provides insight into the individual’s self-perception.
Instructions for Drawing the Tree
When instructing the participant to draw a tree, the administrator should maintain a neutral and non-directive approach; The standard instruction is simply to “Draw a tree, as best as you can.” It’s crucial to avoid providing any specific details or suggestions regarding the type of tree, its size, or surrounding environment.
The participant should be given a fresh sheet of paper and encouraged to draw freely, without erasures or corrections. The administrator should observe, but not interfere, with the drawing process. The focus is on spontaneous expression, capturing the individual’s unconscious perceptions and feelings.
Allow ample time for completion, typically around 15-20 minutes, and avoid rushing the participant. After the drawing is finished, inquire about the details – asking them to tell you about the tree they’ve drawn, what kind of tree it is, and what’s happening in the picture. This provides valuable contextual information for interpretation.
Remember, the goal isn’t artistic skill, but rather the symbolic representation of the individual’s inner world. The tree serves as a projective stimulus, revealing underlying emotional states and personality characteristics.

Common Interpretations of Tree Characteristics
A large, healthy tree generally signifies strong vitality and well-being, representing a robust sense of self and positive life force. Conversely, a small or withered tree may indicate feelings of inadequacy, insecurity, or a weakened ego. The presence of dead branches can symbolize loss, unresolved grief, or feelings of being cut off.
The shape of the tree’s crown offers insights into the individual’s thought processes. A full, rounded crown suggests integrated thinking and emotional balance, while a sparse or asymmetrical crown may reflect disorganization or internal conflict. The type of leaves – detailed or simply represented – can indicate attention to detail and reality testing.
A strong, well-defined trunk symbolizes stability and groundedness, whereas a thin or fragile trunk suggests vulnerability and a lack of self-assurance. The roots, often overlooked, represent the individual’s connection to their past and their sense of belonging. Visible, deeply rooted roots indicate a strong sense of identity and security.

Symbolism in Tree Drawings: Branches, Leaves, Trunk, Roots
Branches reaching upwards often represent aspirations and goals, while drooping branches may signify sadness or a sense of defeat. The number of branches can reflect social connections or the extent of an individual’s interests. Leaves, detailed and numerous, suggest a rich inner life and attention to detail; sparse leaves might indicate feelings of emptiness or a lack of energy.
The trunk embodies self-perception and stability. A thick, solid trunk symbolizes a strong sense of self, while a thin or weak trunk suggests insecurity. The presence of knots or damage to the trunk can represent past traumas or unresolved conflicts. The roots are crucial, symbolizing connection to origins and security.
Deeply rooted trees indicate a strong sense of belonging and identity, while shallow or absent roots may reflect feelings of alienation or instability. The way roots are depicted – visible or hidden – can reveal the individual’s awareness and acceptance of their past. Overall, tree symbolism is complex and requires careful consideration.

Drawing the Person
The person drawing reveals self-perception and interpersonal relationships. Omissions, like absent hands, can suggest feelings of powerlessness, demanding further investigation and validation.
Instructions for Drawing the Person
When instructing the participant to draw the person, maintain a neutral and consistent tone, mirroring the approach used for the house and tree. Simply state: “Now, I’d like you to draw a person.” Avoid specifying gender, age, or any other characteristics. Allow complete freedom of expression; the goal is to elicit a spontaneous representation of self-perception.
Emphasize that the drawing doesn’t need to be artistic or “good.” The focus is on what the person chooses to draw, not the artistic skill displayed. Encourage them to draw a complete person – a full body is preferred, but don’t force it if they begin with details. Observe, but refrain from offering guidance or prompting during the drawing process.
Allow ample time, similar to the previous drawings, and note any hesitation or unusual behaviors. After completion, ask only clarifying questions, such as “Can you tell me something about this person?” or “What is this person doing?” Avoid leading questions that might influence their responses. Remember, the drawing itself, and the subsequent narrative, are the primary data sources.
Common Interpretations of Person Characteristics
A person drawing lacking hands can suggest feelings of powerlessness or inadequacy, though it’s crucial to consider drawing skill and self-consciousness. Large eyes often indicate sensitivity or a feeling of being scrutinized, while small or absent eyes might represent avoidance or withdrawal.
The size of body parts relative to each other is significant. An oversized head could signify intellectualization or preoccupation with thoughts, while a diminished body might reflect low self-esteem or physical concerns. Details in clothing can reveal self-image and social presentation.
Facial features, or their absence, are also telling. A detailed face suggests a strong sense of identity, whereas a minimal or absent face may indicate identity confusion or difficulty with self-representation. The overall presentation – active, passive, realistic, or distorted – provides clues about the individual’s self-perception and emotional state. However, remember these are tendencies, not definitive diagnoses.
Symbolism in Person Drawings: Head, Body, Limbs, Facial Features
The head typically symbolizes thought, intellect, and self-perception. Its size relative to the body can indicate intellectual focus or a disconnect from physical reality. A large head might suggest overthinking, while a small head could represent concrete thinking or a lack of self-awareness.
The body represents self-esteem and vitality. A well-defined body often correlates with a positive self-image, whereas a weak or fragmented body may indicate feelings of inadequacy. Limbs symbolize action and interaction with the world; missing or poorly drawn limbs can suggest feelings of helplessness or difficulty in navigating life’s challenges.
Facial features are crucial for understanding identity. Eyes represent how the individual perceives the world and is perceived by others. A mouth signifies communication and emotional expression. Absent or minimal features can indicate avoidance or difficulty expressing oneself. Remember, symbolism is nuanced and requires careful consideration within the broader context of the drawing.

Scoring and Interpretation
HTP scoring involves analyzing omissions, distortions, and specific characteristics within drawings. Valid scoring systems exist, but content interpretation must remain cautious and objective.
Overview of HTP Scoring Systems
Historically, HTP scoring lacked standardized, psychometrically robust systems, leading to subjective interpretations. However, efforts have emerged to create more reliable methods. Some systems focus on quantifiable features – size, placement, line quality, and specific details within each drawing (house, tree, person).
These systems often assign numerical values or categories to these features, aiming for greater objectivity. For instance, a scoring system might assess the size of the person’s head relative to the body, or the presence/absence of certain details like windows or doors. Sentence completion tasks, while less efficient than surveys, offer a rating scale (e.g., 1-5, negative to positive) for responses, yielding a total adaptability score.
Crucially, the validity of these systems rests on adhering strictly to the defined scoring criteria. Interpreters must avoid injecting personal biases or extrapolating beyond the system’s established conclusions. While some findings – like a person drawn without hands – consistently suggest distress, the specific nature of that distress requires further investigation using more validated methods. The key is to use scoring as a starting point for hypothesis generation, not definitive diagnosis.
Analyzing Omissions and Distortions in Drawings
Omissions and distortions within HTP drawings are considered significant indicators, though their interpretation demands caution. A missing element – like a door on the house or hands on the person – doesn’t automatically equate to a specific pathology; context is paramount. Such features may reflect conscious or unconscious avoidance, representing areas of difficulty or conflict for the individual.
Distortions in size, shape, or placement also warrant attention. An unusually large or small element might symbolize its perceived importance or lack thereof. For example, a towering tree could represent overwhelming feelings, while a diminutive figure might suggest feelings of inadequacy. However, it’s vital to differentiate between symbolic representation and simple artistic skill or preference.
A supervisor’s insistence on kinetic family drawings revealed a child drawing a sister much larger, initially interpreted as dominance. It was later discovered the sister was simply taller. This highlights the danger of premature conclusions. Analyzing these features requires careful consideration of the entire drawing, alongside other assessment data, to formulate informed hypotheses.
Considering Contextual Factors in Interpretation
HTP interpretation isn’t conducted in a vacuum; contextual factors are crucial for accurate understanding. Age, cultural background, developmental level, and presenting concerns all significantly influence drawing content. A child’s drawing will naturally differ from an adult’s, and cultural norms can shape symbolic representations.
Furthermore, the individual’s immediate circumstances – recent stressors, family dynamics, or traumatic experiences – must be considered. A drawing created during a period of crisis will likely reflect that emotional state. It’s essential to gather a comprehensive history and integrate HTP findings with other assessment data, like interviews and behavioral observations.
Reliance solely on rigid scoring systems can be misleading. While scoring systems offer structure, they shouldn’t override clinical judgment. The clinician must consider the unique individual and their specific context, avoiding overgeneralizations or imposing pre-conceived notions. Valid interpretation demands a holistic approach, acknowledging the complexity of human experience.

Limitations and Considerations
HTP’s validity and reliability are debated; ethical use requires caution. It’s best used to generate hypotheses, complemented by psychometrically sound tools for definitive conclusions.
Validity and Reliability Concerns of the HTP Test
A significant critique of the House-Tree-Person (HTP) test centers on concerns regarding its psychometric properties, specifically validity and reliability. Establishing strong empirical support for consistent interpretations proves challenging. The projective nature, while intended to bypass conscious defenses, introduces subjectivity into both administration and scoring.
Traditional scoring systems often lack robust standardization and normative data, hindering comparisons across individuals. While certain features – like a person drawn without hands – may signal distress, pinpointing the specific underlying issue remains problematic. A child’s omission could stem from emotional factors or simply artistic limitations.
Furthermore, the HTP’s reliance on symbolic interpretation opens the door to confirmation bias, where clinicians might perceive patterns aligning with pre-existing hypotheses. This reduces objectivity. Though some scoring systems demonstrate sufficient psychometric qualities when limited to their defined conclusions, broader interpretive leaps lack strong empirical backing. Therefore, cautious application and supplementary assessment are crucial.
Ethical Considerations in Using Projective Tests
Employing projective techniques like the House-Tree-Person (HTP) demands careful ethical consideration. Given the inherent subjectivity in interpretation, clinicians must avoid overstating conclusions or presenting them as definitive truths. The potential for misinterpretation necessitates humility and a commitment to avoiding harmful labeling.
Informed consent is paramount. Individuals should understand the exploratory nature of the test and that interpretations are hypotheses, not diagnoses. Clinicians must be mindful of cultural biases potentially influencing both drawing content and interpretive frameworks. A symbol’s meaning can vary significantly across cultures.
Furthermore, the HTP should never be used in isolation. Relying solely on projective data for high-stakes decisions – such as custody evaluations – is ethically irresponsible. It’s crucial to integrate findings with data from standardized assessments and behavioral observations. Maintaining appropriate boundaries and protecting client confidentiality are also essential ethical obligations throughout the process.
Complementary Use with Other Assessment Tools
The HTP test’s greatest value lies in its complementary role alongside more established psychological assessments. Due to its projective nature and potential for ambiguous interpretations, it shouldn’t be used as a standalone diagnostic tool. Integrating HTP findings with data from standardized, psychometrically sound instruments strengthens the overall assessment.
Combining the HTP with structured interviews, behavioral observations, and objective personality inventories provides a more comprehensive understanding of the individual. For example, patterns observed in the HTP can generate hypotheses that are then rigorously tested using questionnaires or behavioral tasks. This approach mitigates the risk of drawing unsupported conclusions.
Specifically, pairing the HTP with measures of cognitive functioning, emotional regulation, and social skills can illuminate the underlying dynamics contributing to observed drawing characteristics. This multi-method approach enhances the validity and reliability of the assessment process, leading to more informed and ethical clinical decisions.
