Updated 7/30/2021 3:44 PM Crystal Lake-based Community High School District 155 will make masks optional for the upcoming school year, the school board and district officials confirmed at a meeting Wednesday night. This week, the Centers for Disease Control and Prevention recommended all teachers, staff, students and visitors in schools wear face masks indoors regardless of their vaccination status. This recommendation was quickly adopted by the Illinois Department of Public Health. Earlier in July, the CDC had said masks should be worn by those who are not vaccinated.
District 155 Superintendent Steve Olson noted that guidance on reopening schools from state and federal officials continues to shift and change quickly.
