Verbal & Logical reasoning
Published occupational IQ research consistently places nurses (rn) at an average IQ of around 113 — the 81th percentile of the general adult population. This sits modestly above the population mean.
Why nurses (rn) cluster at this level
Registered nurses average above the population mean. Nursing selects on a balance of verbal comprehension, quick decision-making under pressure, and applied reasoning.
What this number really means
An occupational IQ average is a statistical mean, not a hiring criterion. The within-profession standard deviation is typically 10-15 IQ points, which means:
- There are highly successful nurses (rn) scoring well above 128
- And highly successful nurses (rn) scoring well below 98
- Conscientiousness, domain knowledge, emotional regulation, and motivation account for far more variance in actual job performance than the difference between, say, IQ 115 and IQ 125 does

How to interpret your own score against this average
If you're considering this profession or already in it, here's how to read a personal IQ result in context:
- If you score 103–123: you're right in the typical range for nurses (rn)
- If you score above 128: you have meaningful cognitive headroom; you'll likely find the abstract demands of the role easier than peers
- If you score below 98: the profession is still entirely accessible to you — many nurses (rn) succeed at this level — but you may rely more on persistence, structured systems, and specialisation than peers do
