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.
A teacher-made test should enable students to demonstrate what they already know and are capable of, so that teachers can tailor their lessons to the needs of their class. Standardized tests do not always fulfill these objectives since they are much less customized to students with special needs and are conducted perhaps once or twice a year.
