It is the intent and purpose of the Legislature in enacting this chapter to encourage local school districts and community college districts to improve their educational systems and to enrich their educational offerings by utilizing, whenever possible and appropriate, resources which exist in the community. Such resources may include, but not be limited to, business, industry, institutions of higher learning, private consulting firms, other school districts, community college districts, the University of California, or the State of California itself. In the implementation of this chapter, particular emphasis is to be placed upon programs oriented toward agriculture, science, business and commerce, vocational education, teacher training, and, with reference to district administration, development of modern budgetary techniques, such as program planning and budgeting.
