For years we have had standardized tests to gage learning in schools. Those tests are flawed.
Many teachers future are based in students success or failure on such tests. That can be good and bad. Teachers can not take the tests for students. Some students are good at tests and some are not. Does that mean the students are smart/dumb? No.
The United States is falling behind in math and science. Making teachers the content of the test does not make students smarter and does not accurately quantify students learning. If anything it wastes time learning having to take pre tests an actually test students at certain times.
If we want to improve our education in any subject we new to revamp our education system.
