Abstract
Business school accreditation depends on a commitment to continuous improvement in achieving the school's mission. Assessment plays a key role in helping a school improve its processes and achieve its mission. This article discusses principles of effective assessment and hindrances to achieving it, as well as the relationship between accreditation and assessment. It gives an example of a mission-based assessment plan for a master's level university and summarizes an excerpt of the plan. The assessment plan proved to be a vital tool in the development of a strategic plan.
