Which term refers to an assessment given before a learning experience to measure baseline knowledge?

• A. Diagnostic assessment
• B. Formative assessment
• C. Summative assessment
• D. Screening assessment

Answer: (A)

Starting point knowledge is the focus: you want to know what students can do and where they struggle before you begin teaching. A diagnostic assessment is designed to uncover those specific gaps, strengths, and misconceptions so you can plan your instruction to meet each learner where they are. It provides detailed insight into what to reteach, what to accelerate, and which supports to put in place, making it the best tool for establishing a baseline.

This type of assessment is different from others in how it's used. Formative assessments occur during instruction to monitor ongoing learning and guide daily teaching choices; summative assessments occur after instruction to evaluate what students have learned overall; screening assessments are quick checks used mainly to flag students who may need more comprehensive evaluation. The diagnostic approach goes beyond a quick screen or a general check by mapping out precise needs before learning begins.
