The impact of achievement testing on a Spring-Spring vs. a Fall-Spring basis in evaluation of compensatory education programs is examined. The effects of the summer vacation period and crossing test levels were examined. Significant decreases in achievement test scores were found, at all grade levels, between Spring and Fall test administrations.…
