How to use the aptitude test percentile calculator
Results from a pre-employment aptitude battery are read as a position inside the group that sat the test rather than as a raw score. The same 70 points means something completely different when the group averaged 50 than when it averaged 80. Enter one section per line with your score, the group mean and the standard deviation, and this page works out where each section sits.
The calculation starts with z = (my score − group mean) / standard deviation. Converting that z-score through the cumulative normal curve gives an approximate percentile, so a score equal to the mean produces a z of 0 and a percentile of 50.0%. Add the benchmark percentile you are working with and the table reports, for every section, whether it sits at or above that benchmark and by how many percentage points, plus how many sections clear it and which one is lowest.
The page does not predict a cut score. Assessment thresholds vary by employer, role and hiring cycle and are generally not published, so the benchmark is a number you supply. It also does not interpret personality profiles and does not estimate a chance of being hired. Keep in mind that percentiles here assume a normal distribution and are approximations.
Frequently Asked Questions
No. Cut scores on pre-employment aptitude and personality assessments differ by employer and are not published, so no forecast is made. The page only places your score inside the group that took the test.
They usually appear on the score report, or in the statistics supplied with a practice battery. Without them relative position cannot be computed at all, so both are required.
That means your score matches the group mean, and the percentile reads 50.0%. Because the figure assumes a normal curve, it is an approximation rather than your exact rank.
