COT in DepEd stands for Classroom Observation Tool, which is an assessment tool used to measure the classroom performance of teachers in the Philippines. The COT rubric is designed to capture a snapshot of a teachers instruction during a single classroom observation visit and provides initial data for coaches to begin a conversation with the teacher about instructional practices. The COT assessment is used to support the continuum of practice from beginning to experienced teachers. It is also used as the basis for the hiring system of DepEd. The COT is part of the Results-Based Performance Management System (RPMS) tool, which is used to evaluate the performance of teachers in the Philippines.
