Rising Test Scores
- Linn reviewed accountability testing in K-12 public schools over the last fifty years.
Linn found that when tests are used for accountability purposes (i.e., to reward or sanction schools) there is a rise in test scores over successive years. He explains the rising test scores over successive years as a consequence of using the same questions with the same norms for high stakes purposes year after year.
Linn also found when a new test is introduced; test scores fall to the level of the first administration of the previous test and then begin their upward climb again.
