Achievement tests measure what students have learned after instruction, not their potential or ability to learn. They assess broad content areas and skills using quantitative scoring. Diagnostic tests identify student strengths and weaknesses to inform further teaching. They focus on difficult areas, use simple items without scoring, and pay attention to details. Diagnostic tests are given before instruction to determine prior knowledge and assess learning disabilities, while achievement tests evaluate how well course objectives were achieved.
