If you find the state’s four-color system of tiers a little confusing, scroll for a breakdown of what it means by business sectors.
The state’s Blueprint for a Safer Economy explains: Every county in California is assigned to a tier based on its test positivity and adjusted case rate. At a minimum, counties must remain in a tier for at least 3 weeks before moving forward. Data is reviewed weekly and tiers are updated on Tuesdays. To move forward, a county must meet the next tier’s criteria for two consecutive weeks. If a county’s metrics worsen for two consecutive weeks, it will be assigned a more restrictive tier.
How different are the tiers?
Purple is the most restrictive, especially for education. Schools in the Widespread (purple) tier aren’t permitted to reopen for in-person instruction unless they receive a waiver from local health departments for TK-6 grades.
Schools can reopen for in-person instruction once their county has been in the red tier for at least two weeks.
