Post test instream refers to a method of assessment that takes place after a learning activity or course has been completed. It involves evaluating the knowledge, skills, and understanding gained by a student through a series of tests or assessments that are integrated into the learning process. Unlike traditional post-tests that are administered separately from the learning experience, post test instream allows for continuous monitoring of progress and provides immediate feedback to both the student and the instructor. This approach promotes active learning and helps to identify areas of improvement, making it a valuable tool for measuring the effectiveness of a learning program.
