The phrase 'something to act on' suggests that useful feedback should be:

Research on classroom feedback suggests that a mark alone teaches a student little. A score tells a student where they stand, but not what to do next. By contrast, a short comment that names one strength and one specific step for improvement gives the student something to act on. Teachers who give both a mark and a comment often find that students read only the mark and ignore the comment. For this reason, some schools now return work with comments first and release the marks only after students have responded to them.

Answer and explanation

Correct answer: B. specific enough for the student to put into practice

  1. Step 1: The sentence contrasts a score, which gives no direction, with a comment. Step 2. 'To act on' means the student can do something with it. Answer: specific enough for the student to put into practice. Why not the others: Strictness, length and parent understanding are not the point of the phrase.
