Diagnostic measurement refers to the process of assessing an individual's abilities, skills, or knowledge in a specific area. This type of measurement is often used in educational settings to identify strengths and weaknesses, helping educators tailor instruction to meet students' needs. It can involve various tools, such as tests, quizzes, or assessments, designed to provide clear insights into a learner's performance. The results from diagnostic measurements can guide interventions and support strategies. For example, teachers may use these assessments to determine which students require additional help in subjects like math or reading. By pinpointing areas for improvement, educators can enhance learning outcomes and foster student success.
