Uses of tests and assessments as key elements in five waves of educational reform during the past 50 years are reviewed. These waves include the role of tests in tracking and selection emphasized in the 1950s, the use of tests for program accountability in the 1960s, minimum competency testing programs of the 1970s, school and district accountability of the 1980s, and the standards-based accountability systems of the 1990s.

Some suggestions for dealing with the most severe limitations of accountability are provided.
