The short answer is “yes”. They are required. They are referred to in the California Education Code as a “drop procedure.” Private Schools are required to establish procedures. Public Schools are required to conduct the drop procedure and shall hold them at least once each school quarter in elementary schools and at least once a semester in secondary schools.
Private Schools Only

The governing board of each private school shall establish an earthquake emergency procedure system in every private school building under its jurisdiction having an occupant capacity of 50 or more pupils or more than one classroom. A governing board may work with the Office of Emergency Services and the Seismic Safety Commission to develop and establish the earthquake emergency procedure systems.

A drop procedure practice shall be held at least once each school quarter in elementary schools and at least once a semester in secondary schools.
