About the San Mateo County Four Week Rule: San Mateo County has amended its public health order to state that all parents must place their children in “secondary households” for four (4) consecutive weeks. In an effort to preserve this, registration is restricted to four (4) week blocks (June 8 – July 2, July 6 – July 31, and August 3 – 28). With this, we will still honor our refund policy and refund any weeks if the order lifts.
