Do anyone know if the PCAT release statistics regarding their norm group used for calculating the percentiles?

Like the average scaled scores in each subtest? And the scaled score for 1st, 3rd quarter percentiles?

🙂

Question: If I have a Verbal Ability scaled score of 407 and a percentile rank of 60, what does this really mean?
Answer: Scaled scores for the multiple-choice subtests are always on a scale of 200–600, are based on the number of core (live) items correct, and are
calculated separately for each multiple-choice subtest. Experimental items do
not count towards your score. A percentile rank indicates the percentage of
examines (from the current norm group only) who received a scaled score
lower than a given score. For example, a percentile rank of 60 indicates that
60% of the examinees in the norm group received a lower scaled score on
Verbal Ability than 407.


Well, above is what they have on the pdf......I was just wondering if 407 was actually 50 percentile
