The use of a variety of specific competency tests that measure skill achievement required for high school graduation are reviewed in this monograph. The successful performance of certain competencies ordinarily is viewed as an important adjunct of course work. They are not seen by most schools as a replacement for course work, but rather as one significant step toward giving the diploma. The monograph addresses the dual question of assisting students while at the same time insisting that the diploma regain meaning. It provides a background to the competency test movement, and reports on the initiatives taken nationwide to use applied performance tests as a requirement for graduation. Items are presented for several competency tests in current use in the areas of mathematics, reading, writing, democratic process, art, music, and money management. Appendices contain lists of states and schools using competency tests and legislation and State Board rulings concerning competency tests. (RC)
