Mayor Bill de Blasio continued to explain his plan for outdoor learning for New York City schools on Tuesday.

The mayor says outdoor learning will be up to each individual principal on whether they want their schools to participate.

As of Tuesday, Schools Chancellor Richard Carranza says 243 schools have submitted plans for outside learning options.

The mayor also discussed the "School Ventilation Teams” that will be hired to make sure every classroom is safe for students. He says agencies are coming together to make sure every room in every school is inspected. Rooms that do not pass inspection will not be used, according to the mayor.

Inspections started Tuesday and will continue until Sept. 1.

The DOE will also be doing safety checks along with School Ventilation Teams. The DOE is using a checklist to monitor the readiness of school classrooms, including room size and occupancy and making sure it is good for social distancing. Windows will also be tested to make sure they open, as they will need to be able to open

The mayor says the city will make necessary changes in rooms that need it before the start of the school year, and if necessary, will take classrooms offline until they are ready for use.
