California Code, Education Code - EDC § 44965

The governing board of any school district shall provide for leave of absence from duty for any certificated employee of the district who is required to be absent from duties because of pregnancy, miscarriage, childbirth, and recovery therefrom. The length of the leave of absence, including the date on which the leave shall commence and the date on which the employee shall resume duties, shall be determined by the employee and the employee's physician.

Disabilities caused or contributed to by pregnancy, miscarriage, childbirth, and recovery therefrom are, for all job-related purposes, temporary disabilities and shall be treated as such under any health or temporary disability insurance or sick leave plan available in connection with employment by any school district.

Except as provided herein, written and unwritten employment policies and practices of any school district shall be applied to disability due to pregnancy or childbirth on the same terms and conditions applied to other temporary disabilities.

This section shall be construed as requiring the governing board of a school district to grant leave with pay only when it is necessary to do so in order that leaves of absence for disabilities caused or contributed to by pregnancy, miscarriage, or childbirth be treated the same as leaves for illness, injury, or disability.
