California Code, Education Code - EDC § 56836.39

(a) A quality education ensures that pupils receive appropriate interventions and services as needed before the pupil falls behind academically.

(b) Early intervention services and supports provided to children who are at risk of falling significantly behind, including children with disabilities, can reduce the need for additional services in future years.

(c) Pupils with disabilities who are taught within the general education classroom with supports and systematic instruction achieve better outcomes in the areas of academics, communication, and behavior.

(d) In order to ensure the success of pupils with disabilities, additional resources for early intervention and preschool should be provided to school districts to support young learners with disabilities and those at risk of requiring related services.
