1) The policy for marking student work is to mark core subjects every two weeks and non-core subjects every three weeks. Marking can be done by peers or self-marking but must also be marked by the teacher every half term for non-core subjects. Comments should include strengths, improvements, and a student response. 2) Suggested marking techniques include acknowledgment marking of 5 books per lesson, dot marking to note strengths and improvements, and using a yellow box to focus student improvements on a specific paragraph. Process praise focuses on effort rather than ability. 3) Self-assessment and student reflection are effective for understanding improvement areas and measuring progress, and may be more powerful than peer assessment.
