The document discusses issues around how mentor teachers assess student teachers during professional experiences. It notes that mentor judgements can vary depending on the school/site and individual mentor's experience. Student results also differed based on their relationship with the mentor and the mentor's personal views. Interviews found that while most placements go well, some mentors are too lenient or harsh in their assessments. Developing clearer assessment criteria and understanding the student-mentor relationship could help improve consistency between mentor judgements.
