Any system of standardized testing where everyone is given the same test assumes that all students learn at the same rate. But this is not the case. Talented students and un-talented students should not be measured by the same test. Handing down a standard national test from the top is bound to end up with a "one-size-fits-all" result that doesn't suit the weakest or the best students. In the United Kingdom, national testing was introduced in 1988. By 2002, 90% of students at the best schools got the top grade, whilst 300,000 of the United Kingdom's worst pupils failed to pass. The national test 'has not only become too easy for the academically able, but it is still too difficult for the bottom 40 per cent, who cry out for. courses to help them make sense of their last three years of compulsory schooling’1. A ‘one-size-fits-all’ national test does not adequately measure the ability of the student, and fails to motivate students in their education. The best students find them too easy, the worst students find them too difficult. 1 Clare, J. 2003, August 5. One-size-fits-all exams fail the worst as well as the best.

National, standardized tests are a poor measure of student learning
