Monitoring Learning Progress

It is essential to monitor the learning progress of each candidate through continuous appraisal and regular assessment. It not only helps teachers to evaluate students, but also students to evaluate themselves. The monitoring be done by the staff of the department based on participation of students in various teaching /learning activities. It may be structured and assessment be done using checklists that assess various aspects. Checklists are given in Section IV.
