Autism: what actually helps

There is no single therapy for every autistic child, no medication that treats the core features of autism, and no cure. What exists is a menu of 28 evidence-based practices, identified by the National Clearinghouse on Autism Evidence and Practice (NCAEP) at UNC's Frank Porter Graham Institute after reviewing research from 1990–2017 — matched to your child's goals.

How a practice earns its place: for example, two high-quality group studies by different research groups, or five high-quality single-case studies by at least three groups with 20+ participants total. When a provider can't name the practice they're using, that's a red flag.

The evidence-based practices, in plain language

Practice	Typical fit	What it is
ABA — Applied Behavior Analysis (the umbrella)	All ages	Teaching by understanding what comes before and after a behavior, reinforcing desired skills, and measuring progress. CDC: behavioral approaches 'have the most evidence for treating symptoms of ASD.' Modern delivery is usually naturalistic and play-based for young children — ask any program: What goals? Who chose them? How is my child's distress handled?
Discrete Trial Training (DTT)	Early childhood–early elementary	One ABA teaching style: break a skill into tiny steps, teach in repeated trials, reward correct responses. Best as one tool among others, not a whole day.
Pivotal Response Treatment (PRT)	Toddlers–elementary	The other main ABA style: teach 'pivotal' skills — motivation, starting communication, self-management — during natural, child-led play and routines.
Naturalistic Intervention & NDBIs (incl. ESDM)	Toddlers–elementary	Teaching inside play and daily routines, following the child's interest. The Early Start Denver Model (ESDM) blends developmental and ABA principles for ages 12–48 months.
Structured teaching / TEACCH	Preschool–high school	A classroom framework: organized spaces, visual schedules and work systems, expectations made visible and predictable. Built on the idea that autistic learners thrive on consistency and visual information.
Visual Supports & Schedules	All ages	Picture/word schedules, first–then boards, labeled areas, visual timers — they show what, where, in what order, and when it's finished. One of the highest-value, lowest-cost tools at home and school.
Social Narratives / Social Stories	Elementary (adapted for older)	A short, clear story describing a social situation, what to expect, and what the child can do. Works best short, specific, and read before the situation.
PECS & AAC — communication	Any age communication isn't reliable yet	PECS: the child hands over a picture to communicate, building toward sentences. AAC: any tool beyond speech — signs, picture boards, speech-generating devices/apps. Key fact: AAC does not hold back speech — it gives a child a way to communicate now.
Functional Communication Training (FCT)	All ages	Find what a challenging behavior is 'saying' (for example, 'I need a break'), then teach a clear, easier way to say it — and honor it. Paired with Functional Behavioral Assessment.
Parent-Implemented Intervention	Toddlers–elementary (coaching used with teens too)	Professionals coach parents to use strategies during play, meals, bath, and homework — parents deliver the everyday practice.
Speech-Language Therapy	All ages	Builds understanding and use of language: words, sentences, conversation, social communication; also supports AAC. At school it's a related service on an IEP.
Occupational Therapy (OT)	All ages	Builds independence in daily skills — dressing, eating, handwriting — and helps with sensory responses that interfere. Ayres Sensory Integration® specifically (not generic 'sensory activities') is the version on the evidence list — ask what model a provider uses.
Peer-Based Instruction, Social Skills Training, Video Modeling, Self-Management, CBT strategies	Elementary–high school	Practice skills with trained peers; explicit social-skills groups; learn by watching a video of the skill; the student monitors their own progress; CBT-based strategies for anxiety and flexibility (mainly verbal older children/teens).
The toolkit practices	All ages, all settings	Antecedent-Based Interventions, Prompting, Reinforcement, Task Analysis, Time Delay, and Technology-Aided Instruction — change what happens before a task, give just-enough help and fade it, reinforce specifically, break tasks into steps, use tech for independence. This is how the bigger programs are actually delivered day to day.

Also on the full NCAEP list: Behavioral Momentum Intervention, Direct Instruction, Differential Reinforcement, Exercise & Movement, Functional Behavior Assessment, Modeling, Music-Mediated Intervention, Response Interruption & Redirection — and Extinction, a specialist-supervised procedure that is not a do-it-yourself home technique. Free AFIRM training modules teach each practice: autismpdc.fpg.unc.edu/ebps.

An honest note on ABA debates: ABA-based approaches have the largest research base — and the most discussion. Some autistic adults report that older, highly repetitive or compliance-focused programs felt harmful. Modern providers increasingly emphasize naturalistic, play-based delivery, the child's assent, and functional goals (communication, independence, safety). Whatever the model, you can ask about goals, assent, data, and how skills carry into real life — and you can get a second opinion. No source in our research endorses aversive or punishing procedures.

Early intervention: free, and earlier is better

Under age 3 — IDEA Part C

Every state runs an early-intervention program for infants and toddlers with developmental delays. Services are written in an IFSP (Individualized Family Service Plan) and delivered mostly at home or childcare, free or at reduced cost. You do not need a doctor's referral or a diagnosis to call. CDC's words you can copy: "I have concerns about my child's development and I would like to have my child evaluated to find out if he/she is eligible for early intervention services." Find your state's program at cdc.gov/FindEI.

Ages 3–21 — IDEA Part B / Child Find

School districts must identify, locate, and evaluate all children with disabilities who may need special education — including preschoolers not yet in school, private-school and homeschooled children. Part C programs must notify families about preschool services at least 90 days before a child's 3rd birthday, so an IEP can be in place by age 3 if the child is eligible. The full how-to is on our Know Your Rights page — and our letter generator writes the request for you.

IEP vs 504, in one breath

An IEP (under IDEA) is for a child who fits a disability category — autism is one of the 13 — and needs specially designed instruction: it carries goals, services, and strong parent rights. A Section 504 plan is a civil-rights access plan: accommodations (extended time, breaks, assistive tech) for a child who can learn in general education with support. A medical diagnosis of autism does not automatically mean school eligibility, and vice versa — you don't have to pick one in your letter; ask for evaluation under both.

Behavior support at school: FBA/BIP, explained plainly

If behavior is getting in the way of learning, the school should first do a Functional Behavioral Assessment (FBA) — a structured investigation, using observations and interviews, of when a behavior happens, what tends to come right before it, and what happens right after, to form a testable idea about its function: what the behavior gets or avoids for the student, such as escaping a too-hard task, getting adult attention, or meeting a sensory need. (The FBA itself is an evidence-based practice.) The team then writes a Behavior Intervention Plan (BIP) from that idea, with three kinds of strategies: prevent the trigger (shorten or support the task, offer choices, schedule breaks), teach and honor a replacement skill that meets the same need more safely (asking for a break with words, a card, or a device), and respond in ways that reinforce the new skill and don't accidentally reward the old behavior — plus a simple way to record whether it's working, and a date to review it. Parents are team members in this process. A plan that is only consequences and punishments — no FBA, no prevention, no taught replacement skill — is not a function-based plan; ask, in writing, for an FBA if behavior is leading to repeated removals or suspensions.

School services commonly provided (depending on the IEP): specialized academic instruction, speech-language therapy, occupational therapy, counseling, social-skills instruction, a behavior plan, assistive technology and AAC devices, and extended school year when the team documents need. Ask the team to tie each service to a goal and say how progress will be reported.

At home, by age

Early childhood (toddler–preschool)

Follow your child's lead in play 10–15 minutes a day: imitate, narrate, offer two choices, wait. This is the home version of naturalistic, parent-mediated intervention.
Create gentle communication invitations and honor all communication: a favorite item in sight but out of reach, a paused favorite song — accept a look, reach, picture, sign, or word, and model the next step.
Use a visual first–then board ("First brush teeth, then story"), a simple picture schedule, and warnings before transitions ("two more minutes," visual timer).
Short, clear language; get face-to-face at eye level; praise specifically and immediately.

Elementary (about 6–11)

Visual schedules and checklists for homework, packing a bag, and chores; homework in timed chunks with movement breaks built in.
Preview new or social situations with a short social narrative and a plan ("If it's too loud, I can ask for headphones").
Practice one social or communication skill at a time in real life; brief the other adult in advance when you can.
A calm-down space (not a punishment place) with agreed tools — practiced while calm. Share one system with school: same break card, same words.

Teen (about 12–18)

Shift from schedules for them to self-management by them: phone reminders, shared calendars, checklists the teen designs; review weekly.
Teach real-world scripts explicitly: self-advocacy ("I need the instructions in writing"), workplace basics, online safety, consent and relationships.
Take anxiety seriously on its own: predictable routines, gradual practice, and CBT with a clinician experienced with autistic teens if anxiety or depression interferes — don't assume it's "just autism."
Build transition skills — travel, money, cooking, laundry — and make sure the IEP transition plan (by age 16) names real goals, with your teen at their own meeting.
Protect sleep and downtime. Intense interests are a strength and a regulation tool, not something to remove as a default consequence.
