Barbara Jordan served as the hearing officer for three-day adversary evaluation hearings about the pros and cons of minimum competency testing (MCT). This report is the complete transcript of the third day of proceedings. The pro team testimony, led by James Popham, began with William Raspberry, who presented his view of the likely impact of MCT. The remaining witnesses represented ongoing MCT programs in North Carolina and Detroit, stressing the positive effects of MCT on students, the curriculum, and public perceptions of education. George Madaus, the con team leader, began his case by reiterating his team's position: that tests can be helpful in education, but that his team opposes MCT when it is used as a single indicator to deny diplomas, to keep students back in a grade, or to classify students. The witnesses for the con team testified about the impact of MCT on Chicano-Hispanic students, its effect on handicapped and learning disabled students, and the current programs of MCT in New Jersey and North Carolina. The day's proceedings concluded with closing arguments from Dr. Popham and Dr. Madaus. (BW)
