Since April 2022, the Council for Advancement and Support of Education (CASE) and the National Association of Independent Schools (NAIS) have partnered to collect advancement data for the independent school community using the NAIS online tool Data and Analysis for School Leadership (DASL). Used by more than 40 state, regional, and national independent school associations, DASL is a powerful, one-stop shop for independent school data collection. School leaders can use this tool to find actionable data on all aspects of school operations, including enrollment, salaries, and more. The advancement category in DASL draws from the CASE Global Reporting Standards--the global framework for the advancement profession and a set of shared definitions and counting practices--to give schools access to consistent advancement data across the sector. The partnership between CASE and NAIS provides schools with access to comprehensive, standardized data, enabling leaders to benchmark their advancement efforts against those of their peers. These data offer a more complete snapshot of the schools' financial and stakeholder engagement health.
