What test results can I obtain?

The number of questions a student answers correctly on each test is referred to as their raw score. Raw scores are then interpreted by comparing them to the performance of other students of the same chronological age group by means of so-called ‘normative scores’.

The analysis of raw scores plus the age of the students, in the context of large cohorts of students, results in a series of ‘normative scores’. Three types of normative score are provided to interpret students’ performance on CAT4:

Standard Age Scores (SAS)

National Percentile Rank


Further information about CAT4 scores and their interpretation is given in the section entitled ‘Guidance on scoring and reporting results’ in this pack.
