Cal. Education Code § 51100

The Legislature finds and declares all of the following: (a) It is essential to our democratic form of government that parents and guardians of schoolage children attending public schools and other citizens participate in improving public education institutions. Specifically, involving parents and guardians of pupils in the education process is fundamental to a healthy system of public education. (b) Research has shown conclusively that early and sustained family involvement at home and at school in the education of children results both in improved pupil achievement and in schools that are successful at educating all children, while enabling them to achieve high levels of performance. (c) All participants in the education process benefit when schools genuinely welcome, encourage, and guide families into establishing equal partnerships with schools to support pupil learning. (d) Family and school collaborative efforts are most effective when they involve parents and guardians in a variety of roles at all grade levels, from preschool through high school.
