Stanford Achievement Tests | BJU Press Testing & Evaluation

The Stanford 10 Achievement includes a Lexile measure on all Stanford 10 score reports (except for SESAT levels). The test is untimed and in full-color, and special formatting keeps students focused, interested, and on track during testing.

The Stanford 10 is nationally standardized and meets most state requirements. It is available year-round, and you may administer the complete battery or omit the optional sections of the test. Please be aware that some areas may need to use an alternate form of the Stanford test series.

The Stanford Achievement Tests are also available in combination with OLSAT (Otis-Lennon School Ability Test®). To administer any of these tests, you must be listed with us as a pre-approved Stanford tester, which requires a completion of an online test administrator application.You can search for an approved tester in your area using the Tester Locator.
