Which statement best describes formative and summative assessments?

• A. Formative assessments are only formal tests, given at the end.
• B. Summative assessments evaluate learning at the end of a unit.
• C. Formative assessments are not used to guide instruction.
• D. Formative assessments are ongoing and used to guide instruction. Summative assessments evaluate learning at the end of a unit.

Answer: (D)

The idea being tested is how teachers use different assessments to support learning. Formative assessments are ongoing checks during instruction—things like quick quizzes, exit tickets, observations, or quick discussions—that give immediate feedback on what students understand. This information helps the teacher adjust pacing, reteach, or stretch students as needed. Summative assessments come after a unit or course and measure what students have learned overall, often for final grades. The statement that best describes both is that formative assessments are ongoing and used to guide instruction, while summative assessments evaluate learning at the end of a unit.

The other options aren’t as accurate because formative assessments aren’t limited to formal tests at the end, and they are indeed used to guide instruction. While it’s true that summative assessments evaluate learning at the end, that alone doesn’t capture the ongoing, guiding role of formative assessments, making the combined description the most complete.
