Stanford University’s Center for Research on Education Outcomes (CREDO), released a report on estimated learning losses for students in 19 states. CREDO calculated “COVID Slide” measures informed in part by the Northwest Evaluation Association’s estimates of “summer slide” – the erosion of learning that typically happens from the end of one school year to the beginning of the next. CREDO’s enhanced measures are estimates of student learning loss due to the coronavirus pandemic.
The learning loss estimates were translated into lost days of learning, based on a typical 180-day school year. Across the 19 states, the average estimates of how much students lost in the Spring of 2020 ranged from 57 to 183 days of learning in Reading and from 136 to 232 days of learning in Math.
