Book excerpt: Developed specifically to overcome problems with traditional standardized instruments, curriculum-based measurement (CBM) has steadily increased in educational use. These brief assessment probes of reading, spelling, written expression, and mathematics serve to quantify student performance as well as to enhance academic achievement. Their widening use as a means of evaluation and ultimately of instruction, has created a corresponding need to expand the applications of this methodology to diverse populations. This new volume addresses that need by focusing on the broader application of CBM, providing practical new measures, as well as detailing their use with specific student groups.
