We have tried to ensure that the Zone Report (click here to view an example) is easily understood and self-explanatory. However, experience suggests that a few aspects of the report deserve additional comment.
Concerning Our Terminology — Peer Group
IPPT Programs vary in the word they use to identify the set of students with whom a student is compared when assessing her performance and progress. Most programs use "Cohort" or "Class", as in "a student in the Class of 2012". Here we use "peer" and "peer group" as synonyms for whatever word your Program uses to identify your current peer group.

Q: Why do my PAC scores on my Zone reports not match my PAC scores on my Performance reports?
A: This is easily explained. The "Your score" line in the results table in the Zone Report displays your Transformed PAC (t-PAC), not your raw (actual) PAC score. That's why the paragraph above the table refers to "your PAC (score) relative to the mean PAC of an average class of your peers on a test of average difficulty".
The t-PAC expresses your raw (actual) PAC score relative to the mean PAC that would likely be achieved by an average group of students at your level of the curriculum sitting a test of average difficulty. The z-score of your t-PAC is the same value as the z-score for your raw PAC score.
You will find additional information about z-scores, the z-PAC or the t-PAC on our "Understanding Your Performance Report" page. Click on these links:
Q: Why do the mean PAC scores for my Class on my Zone Report not match the mean PAC scores for my Class on my Performance reports?
A: Again, the explanation is fairly simple. The "Class mean" line in the results table in the Zone Report displays the mean used to compute your transformed Percentage Adjusted Correct (t-PAC). That is, the mean likely to be achieved by an average Class at your level in the curriculum sitting a test of average difficulty. The "Class sd" line displays the standard deviation of that hypothetical mean. Without these two statistics, anyone reading the report would be hard pressed to understand your t-PAC scores.
