Students in the Houston Independent School District can once again head to the playground during recess and outdoor graduation ceremonies can resume under new guidance released by district officials.

HISD Interim Superintendent Grenita Lathan laid out changes to the district’s Communicable Disease Plan in a letter sent to parents Thursday.

Among the changes are the reopening of playgrounds and the resumption of recess. Outdoor graduation ceremonies with a limited capacity will be allowed this year and some end-of-year celebrations for students will be permitted.

The district’s mask and social-distancing policies, however, have not changed. Both are still required in all schools, buildings, and buses.

The changes are effective immediately.
