California Code, Education Code - EDC § 37600

It is the intent and purpose of the Legislature in enacting this chapter to authorize public school districts of any type or class to establish, maintain, and operate their educational program under a continuous school program, to be conducted throughout the entire school year.

The Legislature is especially concerned and aware of the mounting costs of acquisition and construction of school sites and facilities, and is, therefore, desirous of providing a procedure whereby those fiscal burdens may be reduced by increased utilization of existing plants and facilities.

The Legislature is also interested in providing for the replacement of the present system of lengthy summer vacations with shorter periodic vacation periods, which will result in a reduction of the student's summer vacation “learning loss.”
