That decision was made Thursday night by the board of education.
In a letter to families and staff, Superintendent T.J. Schneckloth says this follows recommendations from the CDC that everyone should wear a mask in schools, regardless of their vaccination status. It also follows guidance from the Scott County Health Department.
The board's decision is made possible by a federal judge who ruled earlier this week against the Iowa legislature's ban on mask requirements.
Schneckloth says students are not required to wear masks while participating in athletic competitions but they do have to while on the sidelines or sitting on the bench. Spectators at outdoor events are also not required to wear a mask.
Masks are required for students and staff riding on school buses.
