The Legislature hereby recognizes that, because of the common needs and interests of the citizens of this state and the nation, there is a need to establish a common state curriculum for the public schools, but that, because of economic, geographic, physical, political and social diversity, there is a need for the development of educational programs at the local level, with the guidance of competent and experienced educators and citizens. Therefore, it is the intent of the Legislature to set broad minimum standards and guidelines for educational programs, and to encourage local districts to develop programs that will best fit the needs and interests of the pupils, pursuant to stated philosophy, goals, and objectives.
