This is the sixth report in the "School District Responses to the COVID-19 Pandemic" series, covering changes that occurred in public school districts between May 8 and May 29, 2020. Data for this report were collected on May 27 and 29. School districts' responses for this period were captured by the sixth wave of the American Enterprise Institute's (AEI) COVID-19 Education Response Longitudinal Survey (C-ERLS), a nationally representative survey of public school districts. Findings showed: (1) On average, schools canceled eight days of instructional time due to the pandemic, because of either an extended spring break, a shortened academic year, or a lag between closing buildings and starting remote learning; (2) One in five schools were in districts that offered rigorous remote instruction most closely resembling in-classroom learning, while two in five offered perfunctory instructional programs; and (3) Forty-three percent of schools were in districts that planned for an in-person graduation ceremony--with 26 percent delaying the ceremony and 16 percent on schedule--and 28 percent of schools planned to conduct graduation ceremonies virtually.
