It is easier to teach to the textbook than it is to teach to objectives. It is advantageous for teachers to consider all aspects of the testing process. This would include reasons students perform poorly on tests, teachers' contributions to low test scores, and the best methods for measuring long-term student learning. Finally, of utmost importance to everyone in the classroom is the recognition of the testing responsibilities of both teachers and students. It is a teacher's duty to teach, and it is a student's duty to learn.
Tests determine how well both perform their duties.
