The effort to reward city students for passing AdvancedPlacement tests is part of a growing trend nationally andinternationally. Financial incentives are offered in order to liftattendance and achievement rates. One such program in Dallas, Texasoffers $100 for every AP test on which a student scores a three orhigher.

He takes a random sample of 122 students who took the APtests. Twelve tests are scored at 5, the highest possible score.There are 60 tests with scores of 3 or 4, and 50 tests with failingscores of 1 or 2. Historically, of tests that are taken at thisschool each year, 8% score 5, 38% score 3 or 4, and the remainingare failing scores of 1 or 2.
