What Does a Wonderlic Score of 15 Mean?

A raw score of 15 on the Wonderlic Personnel Test puts you at approximately the 20th percentile — below the population average of about 20.

Where 15 falls on the distribution

The 15 you scored is 6 points below the population mean of 20–22. Roughly 80% of test-takers scored higher. The gap closes faster than most candidates expect: 3–6 points after a focused week of timed practice is typical, which on this part of the curve translates directly into a meaningful percentile jump.

Roles where a 15 is competitive

Role fit: Below typical entry-level thresholds for most employers — focus on practice before retest.

For context: Wonderlic's published occupational data lists the average score for warehouse workers at 17. Your 15 is 2 points below that role's average — closing that gap is usually achievable with one to two weeks of focused timed practice.

Most professional roles set thresholds above this band. The fastest way to cross into the next bracket is timed practice under the real 12-minute clock — pacing, not raw cognitive ability, is what stops most candidates here.

What a few extra points buys you

If you went from 15 to 20 after a week or two of focused practice, your percentile would shift from 20th to 50th — a 30-point percentile gain from a 5-point raw gain. The Wonderlic's distribution is steep through the middle, so each raw point in the 20s and 30s does meaningful percentile work.
