The move in the education sector to focus teacher pay on the testing results of their students may well lead to gaming the system. The reason is that the teachers are not the parents of the students, yet the total burden of the student’s results increasingly fall on the teachers.
Also, the standardized testing ultimately tests the students ability to perform on that test and not a test of the knowledge that the student has required. This result is a serious flaw, but the standardized tests are growing. A blog has an interesting graphic that illustrates the issues involved with overuse of standardized tests.
