“The best test for students is the test made by their teacher. Teachers know what they taught; they test what the students were taught. They get instant feedback. They can find out immediately which students didn’t understand the lesson and need extra help. They can get instant feedback about their own success or lack of success if the students didn’t learn what they taught.
The standardized tests are useless for instant feedback. They have no diagnostic value. The test asks questions that may cover concepts that were never introduced in class. The test is multiple-choice, creating an unrealistic expectation that all questions have only one right answer. The tests may have errors, e.g., two right answers or no right answers or a confusing question. The test results are returned months after the test, meaning that the student now has a different teacher. The test scores give no breakdown of what the student did or did not understand, just a score.”
