This document provides guidelines for proper notebook maintenance and checking by teachers. It states that a notebook represents a teacher's assessment of a student's work and should show both qualitative and quantitative work. It then lists the components that should be included in each subject notebook such as a title page with student details, a topic index at the beginning with columns for topic, date, and sign-offs, term pointers identifying term names and dates, a test index at the back, pagination, and margin lines.
