Tests are set at minimum levels. Tests are too hard. The standards are unrealistically high. Tests are unfair. African-American and Hispanic students fail in large numbers.
Tests cause unhealthy anxiety for students.
They fear failing a test that could fail them for an entire year of school. Tests have questions about values. There's too much testing. And it may be the best route educators and government officials have to public acceptance of the tests and engagement in their refinement. Showing a few sample test questions or a practice exam will not do.
