Questar Test Performance Analysis 3

Question 1

A performance analysis shows that 80% of students in a class answered a particular item correctly. This item's difficulty index (p-value) is:

Accepted Answer

0.80

Answer

The item difficulty p-value equals the proportion of students who answered correctly, so 80% = 0.80.

Question 2

Mapping items to standards ensures that performance data can be translated into targeted instructional decisions aligned to curriculum goals.
