San Diego Unified will officially start conducting school online beginning on April 27.

It is one of the first large area districts to announce a plan to return to grading and formal instruction.

“San Diego Unified will return to instruction next month to guarantee students an opportunity to successfully complete the current academic year, even as physical school facilities will remain closed until public health officials determine it is safe for students to return to classrooms,” the district said in a statement Tuesday.

The district’s plan is meant to answer the concerns of many students about whether they’ll be able to finish the school year or complete course credits to move on to the next grade or graduate.

“The schedule outlined today by the district will give members of the Class of 2020 the assurance they need that they will graduate, whether or not public health officials approve a return to in-classroom instruction,” the district of 103,000 students said in the statement.

The timeline means most students will get about six weeks of formal instruction for the rest of the school year, which for most students ends on June 9.
