Per the New York State Department of Health:
 

Responsible Parties must maintain protocols and procedures for students, faculty, staff, and other individuals to ensure appropriate personal protective equipment (PPE) is used to protect against the transmission of the COVID-19 virus when in indoor school facilities. Specifically, appropriate PPE means, at least, an acceptable mask, which is required to be worn by all individuals in all classroom and non-classroom settings, including but not limited to hallways, school offices, restrooms, gyms, auditoriums, etc. All visitors must wear masks. Masks should have at least two layers of material (e.g. 2-ply). However, Responsible Parties should allow students to remove their mask during meals. Acceptable masks include but are not limited to cloth-based masks (e.g., homemade sewn, quick cut,), and surgical masks that cover both the mouth and nose. Effective June 7, 2021, face masks are not required to be worn outdoors on school grounds, including during outdoor school sports.
