A child under age three may receive early intervention services until age three if the child has a developmental delay, an established risk condition, or is at high risk for a developmental disability.^[1]Title 17, Cal. Code of Regs., section 52022. Early intervention services are much more comprehensive than preventive services. If the regional center tells you that your child does not qualify for early intervention services, you may appeal.^[2]Title 17, Cal. Code of Regs., section 52172. Early intervention services are not part of the Lanterman Act, even though provided by regional centers.^[3]California Government Code section 95000, and following, and Title 17, Cal. Code of Regs., section 52000, and following. A description of early intervention services is in this publication: Special Education Rights and Responsibilities, Chapter 12

For children age three and older to be eligible for regional center services, they must have a developmental disability as defined in state law.
