Correct Answer:
B. End of course
Summative assessment aims to evaluate student learning at the end of an instructional unit, course, or academic year. Its primary purpose is to summarize what students have learned and to assign grades or certify competence. Therefore, option B, 'End of course,' accurately describes its main objective.
- Instruction before class (A) is not an aim of summative assessment; this might relate to pre-assessment or diagnostic activities.
- Find problem (C) is typically a goal of diagnostic assessment, which identifies learning difficulties.
- Check student weakness (D) is more aligned with formative assessment, which provides ongoing feedback to improve learning during instruction, rather than summarizing it at the end.
