California Code, Labor Code - LAB § 3368

Notwithstanding any provision of this code or the Education Code to the contrary, the school district, county superintendent of schools, or any school administered by the State Department of Education under whose supervision work experience education, cooperative vocational education, or community classrooms, as defined by regulations adopted by the Superintendent of Public Instruction, or student apprenticeship programs registered by the Division of Apprenticeship Standards for registered student apprentices, are provided, shall be considered the employer under Division 4 (commencing with Section 3200) of persons receiving this training unless the persons during the training are being paid a cash wage or salary by a private employer. However, in the case of students being paid a cash wage or salary by a private employer in supervised work experience education or cooperative vocational education, or in the case of registered student apprentices, the school district, county superintendent of schools, or any school administered by the State Department of Education may elect to provide workers' compensation coverage, unless the person or firm under whom the persons are receiving work experience or occupational training elects to provide workers' compensation coverage. If the school district or other educational agency elects to provide workers' compensation coverage for students being paid a cash wage or salary by a private employer in supervised work experience education or cooperative vocational education, it may only be for a transitional period not to exceed three months. A registered student apprentice is a registered apprentice who is (1) at least 16 years of age, (2) a full-time high school student in the 10th, 11th, or 12th grade, and (3) in an apprenticeship program for registered student apprentices registered with the Division of Apprenticeship Standards. An apprentice, while attending related and supplemental instruction classes, shall be considered to be in the employ of the apprentice's employer and not subject to this section, unless the apprentice is unemployed. Whenever this work experience education, cooperative vocational education, community classroom education, or student apprenticeship program registered by the Division of Apprenticeship Standards for registered student apprentices, is under the supervision of a regional occupational center or program operated by two or more school districts pursuant to Section 52301 of the Education Code, the district of residence of the persons receiving the training shall be deemed the employer for the purposes of this section.
