Question 8

A teacher administers a unit test after completing a chapter on 'Photosynthesis' to determine if students have understood the concepts before moving to the next chapter. Based on the results, she plans to conduct a remedial class for weaker students. This unit test functions primarily as what type of assessment?

Accepted Answer

B. Formative assessment — Although it's called a 'unit test,' its purpose here is to inform instruction and provide feedback for remedial action *before* moving on, indicating its role in guiding ongoing learning and teaching adjustments. This aligns with the definition of formative assessment. If it were solely for assigning a final grade at the end of a larger instructional period, it would be summative. Diagnostic assessment occurs *before* instruction begins to identify prior knowledge, and achievement assessment is a broader term often encompassing summative evaluation.

D. Achievement assessment
