The history of competency testing and legal issues related to it are reviewed briefly in light of the responsibility of school districts for providing remediation programs for students who have failed the test. The mathematics competencies of the state of Idaho are identified and keyed to four sets of readily available, secondary level Apple compatible software packages. These packages have been analyzed for flexibility and ease in student/teacher use. Several programs for implementation of computer assisted instruction (CAI) in remediation are suggested with guidelines for administrators in selecting from available options and for teachers in using the program for remediation purposes.
