In autumn 2003, the author conducted a study of the best practices in linking assessment and strategic planning in higher education by visiting three institutions that represent models in integrating these processes. Information was gathered by interviewing faculty, staff, and administrators involved in the institutions' strategic planning or assessment processes and was supported with document review. Analysis of these data resulted in a synthesis of best practices that can be shared with assessment scholars and practitioners who are interested in a model for colleges and universities to follow in developing or modifying their own planning processes. This article presents 10 best practices in using assessment data for strategic planning. These include: (1) Maintain a mission focus; (2) Build a culture of continuous improvement; (3) Acquire or develop personnel with expertise in planning and assessment; (4) Integrate planning and assessment into existing organizational and operational structures; (5) Create expectations for planning and assessment as part of job performance; (6) Include all interested constituencies in crucial phases of planning and assessment; (7) Allow adequate time for deliberative planning and assessment; (8) Ensure that the processes and results of planning and assessment are transparent and highly visible; (9) Routinely make and explain data-driven decisions; and (10) Communicate often and through multiple channels.
