According to the Wisconsin Department of Public Instruction, report cards are at the core of the accountability system. Please visit: http://dpi.wi.gov/accountability and http://dpi.wi.gov/accountability/historical for details on the accountability system.
All schools - private and public - are required to share their most recent school and district report card with parents, along with a list of educational options for students in the district. Due to 2019 Wisconsin Act 185, there are no 2019-20 report cards. Here is the most recent report card from 2020-21.
No report cards were produced in 2019-20. For details see https://dpi.wi.gov/accountability/covid-19.
