The issue of minimal competency testing for high school graduation and grade to grade promotion as a method of emphasizing the teaching of basic skills and guaranteeing that the high school diploma will "mean something" has received widespread legislative attention in recent years. In this report, data pertaining to the enforcement of minimal competency testing in each State are presented. Specific information is provided by State with regard to Federal legislation (pending), State legislation (enacted and failed), State board of education rulings, State department of education activity and local district activity. It is noted that as of April 1976, four States had enacted legislation and four State boards of education had adopted regulations mandating some form of minimal competency testing. Bills were pending in eight State legislatures, and five State boards had studies underway. The data show that: (1) eleven States have enacted legislation and twenty State boards have adopted regulations regarding minimal competency testing; (2) studies or hearings are in progress in nineteen other States; and (3) State boards are more likely to include life skills and other subjects in addition to the basics than are State legislatures.
