In the late 1800’s, schools were designed and intended to teach obedience. During the rise of our industrial age, big corporations needed workers for their factories. The purpose of the academic system was to create obedient and compliant workers who never asked questions. There were already plenty of scholars at the time.
Thus, the creation of the standardized test. Our academic system itself became a factory to standardize all of the rising students to ensure they fit the desired mold. If the student failed the tests, they would be held back another year to try again.
