SAN FRANCISCO (CBS SF) – After more than a year of disruptions due to the COVID-19 pandemic, the San Francisco Unified School District said they are preparing for a full return to in-person learning at all schools for the 2021-22 school year.

“Given what we know now, everyone, families, staff and students, should plan for a full return to in-person learning in the fall,” SFUSD Superintendent Vincent Matthews said in a statement.

As part of the resumption of full in-person learning, district officials also announced that all schools would start at one of three times: 7:50 a.m., 8:40 a.m. or 9:30 a.m.

The announcement follows a contentious year between parents, city officials, the district and educators over plans to reopen classrooms after the onset of the pandemic.

While San Francisco’s private and parochial schools were largely open during the school year, SFUSD did not resume any in-person learning until April. The district’s first elementary school classrooms opened to in-person learning on April 12, more than a year after the start of distance learning.

Meanwhile, most middle and high school students will continue under distance learning through the end of the year.

Earlier this month, SFUSD announced a plan to bring 12th grade students back on campus for in-person learning for the final weeks of the school year, but the plan has faced major pushback. On Monday, the three state legislators who represent San Francisco called on the state not to give the district $12 million in COVID-19 reopening funds, saying the plan was “a poor attempt to exploit a perceived legal loophole.”

The delays have also prompted a lawsuit by the San Francisco Attorney’s Office and calls among some parents to recall the school board.
