IAR Holland Code: Explore Research, Design, and Physical Prototypes
Explore evidence, alternative designs, and tangible models. Compare industrial design with architecture, then build a paper prototype and examine what you want to do next.
Suppose you develop a design you like, then a simple trial shows that it does not work well. Would you want to investigate, generate another approach, and build a revision?
Investigative: examining a problem, comparing evidence, and checking explanations.
Artistic: developing alternative forms, structures, or expressions for an open problem.
Realistic: working with materials and physical objects so an idea can be tried.
If you want to turn reading into self-measurement, continue into an assessment.
With I first, identifying a question is a useful starting point. The sequence does not require research to finish before creativity begins, or establish design ability.
Willingness to revisit a failed proposal connects inquiry, ideas, and physical feedback. Wanting mainly to make it look better is also useful information, but may point toward a different activity mix.
Industrial designers and architects are editorial task examples. Their official occupational interest profiles may differ from a personal IAR result. These are not official IAR assignments or a personal fit ranking.
Compare the activity you would choose next
IAR versus AIR: would you rather resolve uncertainty about the problem or explore a new expression? A project can support both, with research and creation informing each other.
IAR versus IRA: would you rather sketch another approach or keep adjusting the model already on the table? Both involve inquiry, but invite different kinds of continued effort.
IAR versus IAC: compare handling tangible materials with organizing specifications, checking rules, and maintaining information. A design occupation may need all of them, including areas outside your first three letters.
These comparisons help choose experiences; they are not additional measured results. Close scores and ties call for keeping several activities available, rather than inferring different career destinies from letter order.
Product design and building design offer different constraints
Industrial designers: an idea must survive practical questions
The industrial designers profile connects product use, concepts, and models. O*NET includes preparing designs, refining working models, and assessing feasibility against function, safety, cost, and production constraints.
The editorial reason for including it is the movement between investigating use, developing expression, and physical realization. Would you revise because of practical feedback, beyond enjoying attractive objects?
BLS describes a typical U.S. entry route involving a bachelor's degree and an electronic portfolio. Work may involve clients, manufacturing settings, or testing locations. These are U.S. descriptions, not a universal hiring standard.
For China, check the product specialism, design scope, CAD or modeling tools, materials knowledge, portfolio expectations, engineering and production responsibilities, and applicable product safety requirements.
Someone who enjoys generating ideas but dislikes specifications, budgets, client revisions, and production feedback may find the work disappointing. Try a project before making a larger training commitment.
Architects: spatial ideas enter a chain of responsibility
The architects profile covers spatial requirements, scaled drawings, technical integration, documents, and construction observation. This occupation excludes landscape and naval architects.
The reason for including it is the movement from a problem to a spatial proposal under construction constraints. Detailed checks, explaining trade-offs, and professional coordination matter alongside design.
BLS describes U.S. education, relevant internship experience, and an examination in the usual licensure route. States and the District of Columbia require architects to be licensed. That does not establish eligibility to practice in China.
For China, distinguish design-support roles from registered professional responsibilities. Verify current education, experience, examinations, registration, and signing authority with the appropriate authorities and employer.
Spatial interest does not remove documentation, regulation, long preparation, or repeated coordination. If these conditions are difficult to accept, adjust the exploration before choosing a course. A model exercise cannot substitute for professional qualifications.
Build a paper card stand
This original editorial activity gives inquiry, design alternatives, and physical revision a shared object. It is not a questionnaire item, design examination, or occupational ability assessment.
Inputs: scrap paper or thin card, a pencil, a ruler, and ten identical cards. The fictional brief is to hold them within a 10-centimeter square on a desk and allow one to be removed without pulling others out. These dimensions bound the exercise; they are not product standards.
Write three questions: for example, whether cards slip, retrieval moves the stand, or fewer remaining cards change its behavior.
Sketch two structurally different approaches, explaining the problem each addresses.
Build one model, load ten cards, and try removing one card three times. Record slipping, collapse, or unintended movement.
Change one main factor, such as base width, fold angle, or an edge. Repeat the three attempts.
Compare versions and explain what you retained, rejected, and have not checked.
Completion: produce a problem statement, two sketches, at least one model, and observations tied to a change. The model may fail the brief while the exercise is complete, provided you identify the failure and justify a next revision.
Output and feedback: separately record whether you want to investigate, generate alternatives, or keep making adjustments. A rough model may reflect limited practice; a polished one can still reveal little desire to continue. Do not convert success into an interest score.
If evidence-led revision attracts you, try a second small brief. If inquiry dominates, compare research tasks; if expression dominates, try a visual activity; if making dominates, explore another safe material or structure. An optional willing participant can try removing a card; record their concrete difficulty. Without one, retain the limits of self-testing.
This exercise does not check manufacturing safety, engineering calculations, building regulations, or professional competence. A course, supervised project, or occupational investigation is needed for those questions.
Read the code alongside the full profile
Keep all six scores, questionnaire version, and quality notices. Close scores do not establish sameness or difference; exact tie ordering does not prove stronger interest, and equal displayed integers need not mean identical sorting scores. The 60- and 140-question forms use different score spaces, so do not subtract scores across them. No fixed score-gap rule is supplied here. Include both areas when the third and fourth are close.
Use the occupation library to compare activities, conditions, and preparation rather than relying on the word “design.” Then use the career planning guides to plan knowledge, portfolio work, and training. Compare RIC exploration for diagnosis and handover, or SAE exploration when expression interests you because it helps someone understand and act. Return to career test selection if needed.
Sources and scope
Current pages were read on October 22, 2026. The O*NET occupation pages say Updated 2026; no separate underlying database release number is claimed.
The hypotheses, comparisons, and paper activity are editorial interpretations, not official occupational coding or a validated measurement method. The sources do not establish FermatMind assessment validity or an individual match probability. U.S. requirements do not replace qualification checks in China or elsewhere.
