This paper briefly describes a number of techniques for evaluating students' achievement in mathematics: (1) checklists and rating scales; (2) standardized tests; (3) criterion referenced tests; (4) anecdotal records; (5) student products, including homework and school assignments; (6) teacher-written tests; (7) conferences with students; (8) parent-teacher conferences; (9) oral tests; and (10) sociometric devices. The advantages and limitations of these techniques are briefly discussed, and use of a variety of tests is suggested. Guidelines for the construction of teacher-written tests are also included. (GDC)
