The Orange County thing is not quite that simple (source: I am in Orange County) - what happened was the Orange County Board of Education voted to endorse no restrictions, no masks, full return to school - quite frankly a lot of the meeting was a joke - 30 minutes for public comment and they decided to not read any of the public comments that they solicited. They received over 2500 written comments.
Within Orange County, our school district sent out several notices clearing up the confusion that any decision from the Orange County Board was non-binding, and that our Locally-elected school boards and superintendents will approve and implement plans specific to their districts based on the needs of their schools and communities.
In particular, our district remains committed to following guidance provided by the California Department of Public Health and the Orange County Health Care Agency. The Orange County Department of Education has also worked with local school districts leaders to develop “Orange County Together: A guide to safely reopening schools in the COVID-19 era,” which is based on guidance from the CDPH.
