ObjectiveThis paper describes the creation and refinement of a Workload Estimator to be used at Colleges/Schools of pharmacy to calculate faculty workload. MethodsWe describe the initial development of the Workload Estimator for pharmacy practice faculty, including the consensus-building methodology and the implementation process. Additionally, we describe the annual refinement and expansion of use to pharmaceutical and administrative sciences faculty. ResultsThe final product is an Excel file with built-in multiplication factors used to estimate pharmacy faculty workload. ConclusionThis Workload Estimator was identified as the most comprehensive and readily adaptable tool to estimate pharmacy faculty workload in July 2023 by the American Association of Colleges of Pharmacy, Council of Faculties, and Council of Deans Task Force on Faculty Workload. The Workload Estimator is currently being studied in a multi-institutional implementation study across dozens of diverse programs across the country with norming data and qualitative perspectives on its use being collected and shared with the Academy in 2024.
