This guide is organized into five chapters; (1) an approach to testing--decisions made from test results, types of achievement tests, types and levels of objectives, and test validity, reliability, and practicality; (2) classroom test construction--planning, item banks, item writing, assembly, administration, and scoring; (3) test analysis-item analysis and interpretation of difficulty and discrimination indices; (4) interpretation of test performance--frequency distributions of scores, measures of central tendency, standard deviation, score interpretation, reliability, and measurement error; and (5) procedures for setting standards--minimally acceptable performance, determination of borderline group, and classification errors. An eight-item bibliography and a 55-item glossary are appended. (GDC)
