What do the different terms that are found on the score report mean?
Percentile Rank This shows the relative standing of a student in comparison with other students of the same age or grade. For example, 95% means that a student scored higher than 95% of other students in the same age or grade taking the test during the same time of year (fall, winter, or spring). Stanine This indicates the student’s relative standing in the national norm group and ranges from 1 – 9 with a mean of 5. Standard Age Scores (SAS) on the CogAT and Nonverbal Ability Index (NAI) on the NNAT These scores may be interpreted in terms of how many standard deviation units the score is above or below the mean for the age group. An SAS or NAI of 100 is zero deviations from the mean. The three digit SAS score for the CogAT and the three digit NAI score on the NNAT are used to select a second grade pool of candidates for the full-time AAP (level IV) center program. They are also reviewed as one of the criteria that must be submitted in a screening file. Can students be re-tested? Paren
