The SIR Holland code describes candidates who lean primarily Social with strong secondary Investigative 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 SIR means in plain English
People with a Social lead are typically helpers, teachers, people-oriented contributors. Add a strong investigative pull (the second letter) and a tertiary realistic side (the third), and the SIR profile describes someone who blends those three orientations in roughly that order of strength.
Strengths. Empathy, communication, comfort working with people, preference for human-focused outcomes. The investigative layer adds: curiosity, analytical thinking, comfort with abstract problems, preference for data and evidence.
Common challenges. May find isolating analytical roles draining; benefits from team-based or client-facing work. May struggle with routine work or roles requiring sustained social interaction without intellectual depth.
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 SIR candidates
SIR candidates typically thrive in roles that combine the three orientations in the order shown. The dominant social layer points toward teaching, healthcare or social-service roles.
The investigative 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 SIR 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 SIR 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.
