Principals in Independence might pay a price if students at their schools don’t do well on state standardized tests. The Independence School District plans to base the salaries of its principals on the scores their students acheive on the Missouri Assessment Program test scores. The district plans to begin the evaluation process by the 2003-2004 school year. A spokesman from the American Association of School Administrators questions the wisdom of the plan, saying it’s an awful lot of pressure to place on something that is fairly out of their control.
