Among the new testing developments are the use of objectives or goals in instruction, competency based approaches to instruction, criterion referenced testing, and performance oriented testing. These new approaches often emphasize individualized learning; each student's progress is individually monitored by comparison with clear statements of what students are expected to learn. The careful monitoring of individual student progress required in such a performance based system has created the need for a testing technology which differs in many respects from typical practice. These guidelines are intended to help teachers develop testing skills which meet the demands of a competency based approach to instruction. This guide includes information on fundamental concepts in testing, construction of classroom tests and measurement of attitudes. An annotated bibliography of recent and significant contributions to testing techology, a brief glossary of testing terms, and a list of recommended sources for achievement test items are appended.
