Charleston's autism-support map has a geographic quirk worth knowing before making a single phone call: the regional early-intervention office covering the whole Trident area — Charleston, Berkeley, and Dorchester counties together — is not actually inside Charleston's city limits, and neither is the county disability board's street address; both sit instead in neighboring North Charleston. Add in a city that itself spans two counties (part of Daniel Island falls under Berkeley County, not Charleston County), and matching the right office to your address becomes worth double-checking.

This guide lays out the specific phone numbers, referral rules, and web links behind South Carolina's BabyNet early-intervention system, Charleston County School District's Child Find process, MUSC's diagnostic pathway, and the county disability board that gates Medicaid waiver services — all sourced directly from the agencies that publish them.

Statewide programs, numbers, and rights are on the South Carolina page. This page adds the local entry points that are specific to Charleston (Charleston County).

Early intervention under 3: BabyNet (South Carolina's Part C early intervention system)

BabyNet is the name South Carolina gives its Part C early intervention system, and the state stopped routing new cases through local branch offices — every referral, from a parent, pediatrician, or daycare worker, now goes to a single Central Referral Team, reachable online or at 866-512-8881. Once a case opens, families in Charleston, Berkeley, and Dorchester counties are assigned to the Trident-area BabyNet office at 4130 Faber Place Drive, Suite 301, in North Charleston, where coordinator Lauren Peregrine (843-740-3193) oversees service coordination through age 3.

School districts and special education

Federal law obligates every South Carolina school district to seek out and evaluate students it suspects have a disability at no cost to the family, a duty known as Child Find, and a written request to the district starts that process. Charleston County School District's Department of Exceptional Children handles this for most of the city, but part of Charleston — Daniel Island — sits across the county line in Berkeley County and is served by that district's Special Services office instead, so confirming which side of the boundary a home falls on matters before sending a request.

• Charleston County School District — Department of Exceptional Children — Handles Child Find, IEPs, and Section 504 for most of Charleston; evaluation requests go through your child's school. Charleston County ECPAC is the district's parent advisory committee; no separate district-wide Child Find phone line is posted publicly.
• Berkeley County School District — Special Services — Covers the part of Charleston (including Daniel Island) that sits in Berkeley County rather than Charleston County. District main line 843-899-8600, 229 East Main Street, Moncks Corner.

Evaluation and diagnosis pathways in Charleston

These are hospital and university programs with public intake information. Listing here is informational — it is not a recommendation, and it is not medical advice. Public school evaluation is free and does not require any of these.

• MUSC Children's Health — Developmental Behavioral Services — autism spectrum disorder evaluation alongside assessment for ADHD, Down syndrome, developmental delay, and NICU follow-up care; a first visit typically includes a developmental pediatrician, psychologist, psychiatrist, or social worker reviewing developmental, medical, social, and educational history · 843-876-0444
• Butterfly Effects — ABA therapy (Charleston) — in-home, in-center, in-school, and virtual applied behavior analysis (ABA) therapy for autistic children, plus ABA assessments; the practice states it accepts most major insurance including Aetna, Blue Cross Blue Shield, Cigna, Tricare, and UnitedHealthcare · 888-880-9270

Disability services and waivers: Disabilities Board of Charleston County (local access point for SC's Office of Intellectual and Developmental Disabilities)

South Carolina's Medicaid waiver and long-term disability system — renamed the Office of Intellectual and Developmental Disabilities (OIDD) within the state Department of Behavioral Health and Developmental Disabilities, and still widely referenced under its former name, DDSN — routes Charleston County families through the Disabilities Board of Charleston County for local intake, case management, and eligibility paperwork. That county board's office sits at 1357 Remount Road, Unit #2, in North Charleston; the state's own eligibility-screening line, for families ready to start the Medicaid waiver process directly, is 800-289-7012.

Documented waits and access notes

Wait times change. Each note below links to the public source it came from — confirm current status directly with the program.

• Charleston County Parks and Recreation partners with KultureCity to stock sensory bags — fidget tools and noise-canceling headphones — at three parks and select events, and lends free beach wheelchairs on a first-come basis. (source)
• The South Carolina Department of Education holds districts, Charleston County School District included, to 60 calendar days from parental consent to an eligibility meeting, and to a further 30 days from there to a finished IEP. (source)
• BabyNet's own procedures manual sets a 45-day ceiling, running from a completed referral, for finishing a child's evaluation and holding the first IFSP meeting — the same figure the Trident-area office in North Charleston has to meet for a Charleston case. (source)
• As of a January 2026 policy memo, South Carolina's disability office stopped automatically adding newly eligible people to its Intellectual Disability/Related Disabilities waiver waiting list the moment eligibility is confirmed, a change the Disabilities Board of Charleston County can explain for anyone already partway through that process.
