Cal. LAB § 3075.1

It is the public policy of this state to encourage the utilization of apprenticeship as a form of on-the-job training, when such training is cost-effective in developing skills needed to perform public services. State and local public agencies shall make a diligent effort to establish apprenticeship programs for apprenticeable occupations in their respective work forces. In furtherance of this policy, public agencies shall take into consideration (a) the extent to which a continuous supply of trained personnel is readily available to public agencies to meet their skill requirements in the various occupations which are determined to be apprenticeable, and (b) the application of established programs in the private sector, where appropriate. Public sector apprenticeship programs should be fully compatible with affirmative action goals for the participation of minorities and women in apprenticeship programs.
