Which of the following best describes the purpose of formative assessment?

Concept: Formative assessment is "assessment for learning" -- an ongoing process carried out during instruction to monitor how learning is progressing, diagnose gaps or misconceptions in real time, and use that information to guide and adjust future teaching and learning activities. It is contrasted with summative assessment ("assessment of learning"), which judges outcomes after instruction is complete.

Application: The stem asks which option best captures this ongoing, monitor-and-adjust purpose. Among the four options, only one describes assessment as a continuous feedback loop that tracks a learner’s development and directs what happens next in teaching, rather than a one-time judgment, a peer comparison, or a program-level evaluation.

Cross-check: Checking each remaining option against a different, well-known assessment concept confirms the distinction:

• Comparing one student’s performance against peers describes norm-referenced assessment, which ranks learners relative to each other rather than tracking an individual’s progress toward learning goals.

• Determining a student’s final grade describes summative assessment, which certifies the outcome reached at the end of a unit or course.

• Judging how effective the overall curriculum is describes program or curriculum evaluation, which assesses the design of a course of study rather than an individual learner’s ongoing progress.

Result: The option describing ongoing monitoring of progress that guides future learning is the one that defines the purpose of formative assessment.
