Enrollment management plans have been researched and documented for the last fifty years and literature verifies that the use of these plans has only become more relevant in the 21st century. Strategies and activities for managing enrollment have been defined and shared for most types of institutions, however, there is limited research on the best practices in four-year open enrollment institutions. An institution's admissions policy, such as open enrollment, may have an impact on the approaches used in strategic enrollment management plans. Performing a survey design study on enrollment management strategies and their availability, use, and effectiveness on achieving enrollment goals has helped to define best practices in developing or refining an enrollment management plan. It has also filled a gap in the literature surrounding the best practices of strategies that should be used in these types of institutions.
