A study examined the outcomes of the No Pass/No Play Arizona Board of Education rule that requires pupils to pass all of their classes in order to participate in extracurricular activities. Student records of all 7th through 12th grade extracurricular activity participants in the Mesa Unified School District (Arizona) were reviewed. The data indicated that GPAs (grade point averages) increased somewhat; the percent ineligible fell the first year after implementation but increased slightly the second year; teachers did not appear to give easier grades; students did not take easier classes or fewer classes; the dropout rate was low, but within the ranges experienced in prior years. In addition there appeared to be no clear disparate effect on one or all minority groups and there were differences in ineligibility rates by ethnic groups with the rates of African Americans, Hispanics, and Native Americans being much higher than other groups. The data suggests that the rule was at best a very modest short term success; however, this success was at the cost of having a disproportional impact on minorities, possibly having negative long term consequences, and costing school personnel a great deal of time and effort to monitor and report. These initial results indicate that the costs of this rule may not outweigh the benefits. (CW)
