Overall test reliability will be ensured through reviewing each test’s KR20 score (ranges from 0.0 to 1.0). Scores below 0.7 indicate the test did not do a good job of discriminating between high and low performing students, the test had too many interruptions, material was not adequately covered, or cheating might have occurred. Tests with KR20 less than 0.7 may be completely thrown out, retaken, partially modified, or other action deemed appropriate by the lead instructor
Test item reliability will be ensured through reviewing each question’s class discrimination score (ranges from -1.0 to 1.0).

Questions may be completely thrown out, modified, or other action deemed appropriate by the lead instructor.
Test item validity will be ensured through reviewing the percent of the class that answered the question correctly.
