Aligning a school board policy manual with the faculty handbook would be an excellent application of systems thinking in support of school district mission and goals. This article talks about changing sound assessment practice in accordance with the school's proper policy. One obstacle to changing assessment practice is the prevailing belief that assessment is entirely about measurement. That belief limits the ability to use assessment to promote learning, not simply to measure it. As people adopt more productive beliefs about assessment and student learning, they need to ensure those beliefs are not contradicted in board policy. In fact, they must ensure their beliefs are clearly supported in a system of policies that are focused on sound assessment practice and the goal that all students learn well.
