Teacher Review can be enabled for quizzes, tests, and/or exams. When enabled, students will be stopped at the corresponding assessment so an educator can review their work. If you enable Teacher Review for quizzes, each time your students reach a quiz in the course, the system will lock the assessment. Students will not be permitted to take the quiz until you unlock it. But before you do that, you can review your students' responses to subjective questions, eNotes, and other work through the gradebook to ensure the student is adequately prepared to take the assessment.
Pretests are not blocked by teacher review.
