During the 2020-21 school year, Wisconsin districts applied to the Department of Public Instruction for waivers to respond to the evolving public health pandemic. This analysis, which focuses on districts utilizing Hours of Instruction and Length of School Day flexibilities, was designed to take stock of what was learned during this unusual year and to uncover possible new innovations. In June of 2021, the text of 110 waiver applications was analyzed for key themes. While some districts submitted waivers preemptively in anticipation of a need, others sought flexibility in response to urgent circumstances. As a result, original waiver language may not have reflected the strategies ultimately used. To better understand district experiences, districts were surveyed and interviewed during July of 2021. WMCC also did a brief web scan of innovative ideas from across the country to provide additional context for this analysis.
