Yes, people can apply for regional center services and get an assessment if:

• They are suspected of having a developmental disability
• They are at high risk of parenting a baby with a developmental disability. Parents and infants in this group may receive assessment services and preventive services. ^[1]Sections 4642 and 4644
• They are under age 3 and at high risk of becoming developmentally disabled. Parents and infants in this group may receive assessment services and preventive services.^[2]Sections 4642 and 4644.
• They are age 3 or 4 and may be “provisionally eligible.” This means they don’t qualify as having a “developmental disability.” But, with provisional eligibility, they can get full regional center services while they are 3- and 4-years-old. ^[3]Section 4512(a)(2)
