This volume provides an outline of critical high school equivalency skills in mathematics, a test scoring procedure designed to assess these skills, and a guide to the use of 12 publications which would be useful in instruction. The volume is intended for use by teachers of students who are preparing to take the Test of General Educational Development (GED). In order to use this guide, the teacher first administers the California Achievement Test and scores it using the forms provided. These forms classify items on 74 aspects of mathematics content. The teacher, using this classification to determine which content areas the student must work on, can then refer to the guide to select instructional materials related to the appropriate content area. For each of the 74 topics, materials are classified as useful in lower level reinforcement, upper level reinforcement, or GED test simulation. (SD)
