There are several types of feedback that can be provided to test takers both during and after the test taking process. Feedback can include messages displayed on the screen such as whether an answer is correct or incorrect, as well as more detailed text, graphics, or links. Test generators allow configuring pre-test, during test, post-test, and post-review feedback such as the option to show correct answers, send emails with results, or provide a study guide. The level and type of feedback can be customized based on the test author's needs and preferences.
