The IAR Holland code describes candidates who lean primarily Investigative with strong secondary Artistic and tertiary Realistic traits. Below: what this means in plain English, the 8 Nigerian university courses that match the profile best, and how to use the code with your JAMB strategy.
What IAR means in plain English
People with a Investigative lead are typically thinkers, researchers, analytical problem-solvers. Add a strong artistic pull (the second letter) and a tertiary realistic side (the third), and the IAR profile describes someone who blends those three orientations in roughly that order of strength.
Strengths. Curiosity, analytical thinking, comfort with abstract problems, preference for data and evidence. The artistic layer adds: creativity, originality, expressive communication, comfort with ambiguity and self-direction.
Common challenges. May struggle with routine work or roles requiring sustained social interaction without intellectual depth. May find highly regulated or routine work suffocating; benefits from creative latitude.
Treat your three-letter code as a useful summary rather than an identity. Most undergraduates' profiles shift through university and the first few years of work; revisit the quiz in a year or two.

Career paths for IAR candidates
IAR candidates typically thrive in roles that combine the three orientations in the order shown. The dominant investigative layer points toward research, analysis or scientific roles.
The artistic secondary layer reshapes those roles. For example, an SI profile (Social-Investigative) suits clinical medicine; an IS profile (Investigative-Social) suits research-driven healthcare like public health and epidemiology. Both involve health, but the day-to-day balance of patient contact versus analysis differs.
How to use your Holland code with JAMB
Use it as one of four signals. Combine the IAR interest profile with: your academic stream (science / arts / commercial), your JAMB readiness (UTME score and subject combination), and your practical preferences (region, fees, study duration). The /what-to-study quiz on this site blends all four and produces a shortlist of 5 courses with the universities that fit your score.
For JAMB candidates with a clear IAR profile but no decided course, start by treating the top 3 matches above as primary options. Use their course pages to confirm the UTME and O'level subject combinations, then plan your JAMB strategy around those subjects.
