However, the test window has a direct impact on growth calculations, so do not overextend the window. In some cases, you might adjust your test window dates to include tests that were started outside the window. Use caution when making decisions based on tests that do not meet growth criteria. Screening tests: Screening tests and some course-specific tests do not produce a growth measure.

Note: If tests have the same standard error, then the test that either is most recent or has the highest RIT score becomes the growth measure.

Any duplicate test scores, even though still valid, are not considered for growth comparisons.

Multiple tests: If a student completes the same test multiple times in a term, the test with the lower standard error becomes the growth measure.

Test dates are when students started testing, so a student could complete a test outside the test window, and it would still count for growth.

Test window dates: Tests must fall within the dates designated for testing (“test window”).

Three other criteria control whether a test event is considered part of official growth measures: For details, see How to Retest Students within a Term. For invalid tests, retesting could be an option, if appropriate for the student.
