Which statement best defines a formal assessment?

• A. A formal assessment is a standardized test used to evaluate a student's knowledge.
• B. An informal observation during class is a formal assessment.
• C. A student self-check is a formal assessment.
• D. A teacher's opinion without data is a formal assessment.

Answer: (A)

Formal assessments are official measures of student learning that use standardized procedures and scoring. They’re designed to be administered the same way to all students, with established criteria and documented validity and reliability, so results can be compared and used for grading or accountability. A standardized test used to evaluate what a student knows fits this description precisely, which is why it’s the best choice. In contrast, informal observations are unstructured and not standardized, self-checks are typically informal self-assessments, and a teacher’s opinion without data isn’t based on measured evidence.
