Categories are determined based on the metrics outlined in the PHD COVID-19 Risk Levels by County document linked to the left. These categories are recommendations only and final decisions are made by local school boards. Private and charter schools should use the category based on the address of their facility and associated school district boundary. These are weekly assessments of community spread and will updated on Thursdays. If category designations are adjusted then schools and families should expect transition time as changes may or may not be immediate.
