What constitutes a teacher-made test? A: A teacher-made test is an alternative to a standardized test, written by the instructor in order to measure student comprehension. Teacher-made tests are considered most effective when they are implemented as part of the education process, rather than after the fact. It is recommended that they include visual and auditory tasks, have varying levels of difficulty and offer easy-to-follow instructions.
Another advantage is that the teacher controls the format and can go beyond the traditional multiple-choice and true-false assessments used in standardized tests. Teachers can also modify their tests on a more regular basis as needed. The lack of uniformity in teacher-made tests is another drawback.
