Minimum competency testing in American schools was examined for its effects on low-achieving high school students. Interviews with educators and results of a survey of more than 700 high school students were used. In the view of many educators, minimum competency tests were so rudimentary as to not be much of a barrier to completing school. Most of the students considered competency testing policies to be beneficial. However, those who failed such tests initially were more likely to be doubtful about their ability to earn a diploma. About half of the students believed that such testing caused some students to drop out. Statistical information is presented in 12 tables, and the National Survey of Student Experiences with Graduation Tests and the master question list for educator interviews are appended. (SLD)
