Higher education teaching certificate programs can improve graduate students' and postdoctoral scholars' teaching while preparing them for their future roles as faculty, providing a multi-tiered benefit to universities' teaching goals. This article documents the decision points and initial success of a redesign of one such teaching certificate program." As part of the redesign process, 10 universities' programs were reviewed and used as a benchmark. The programs' learning objectives and assessments, along with their connections to the literature, are discussed in detail. A new flexible pathway through the certificate program emerged, tapping into courses, workshops, and online resources for content delivery, effectively expanding access to more participants. Preliminary outcomes include increased enrollments from a wide range of disciplines and new opportunities for partnerships with academic departments.
