Autism Acronyms and Terms Made Simple: A Parent’s Guide from Achieve Beyond

Written by Tara Karen, M.S. Ed, BCBA, LBA

Navigating the world of autism services can sometimes feel like learning a whole new language. Acronyms, therapy models, and clinical terms get tossed around and before you know it, it’s easy to feel lost in translation.

At Achieve Beyond, we believe informed families make empowered decisions. When parents understand the language of therapy, collaboration becomes stronger, goals become clearer, and children thrive.

Whether you’re exploring ABA therapy through your child’s health insurance, seeking out school-aged, preschool, or early intervention services in speech, occupational, and/or physical therapy, this guide offers clear explanations grounded in modern, compassionate practices.

Core Autism Acronyms & ABA Therapy Terms

ASD – autism spectrum disorder

Autism is a neurodevelopmental condition that influences how a person communicates, learns, and experiences the world. The word spectrum reminds us that every autistic individual is unique — with their own strengths, interests, and support needs.

• The autism wheel is a great way for us to view autism as areas of individual strengths and areas needing supports, rather than thinking in a linear way of “high-functioning” or “low-functioning,” which are outdated and not neurodiverse affirming.

ABA – Applied Behavior Analysis

ABA therapy uses the science of learning and behavior to teach meaningful, real-life skills. At Achieve Beyond, our ABA approach is modern, compassionate, and affirming. We focus on communication, independence, and quality of life — not compliance.

BCBA – Board Certified Behavior Analyst

A BCBA designs, monitors, and adjusts each child’s therapy plan. They use data and collaboration with families to ensure goals align with what truly matters — connection, progress, and functional growth.

FBA – Functional Behavior Assessment

An assessment that helps identify the function or purpose of a behavior — for example, gaining attention, escaping a task, or meeting a sensory need. Understanding the “why” allows therapists to teach supportive alternatives.

BIP – Behavior Intervention Plan

A customized plan that provides proactive strategies to prevent challenging behaviors and teaches new, functional skills in their place.

DTT – Discrete Trial Training

A structured method that breaks complex skills into small, achievable steps. DTT can be helpful for teaching early learning skills through clear instruction and positive reinforcement.

NET – Natural Environment Teaching

Learning that happens in everyday settings — at the park, during playtime, or while sharing snacks. NET helps children apply skills naturally and generalize them to real-life situations.

Reinforcement

The most powerful tool in ABA, and how we all get out of bed in the morning. Utilizing motivation to encourage behaviors to occur more frequently. Modern ABA emphasizes positive reinforcement, celebrating effort, success, and growth to build lasting confidence.

Prompting and Fading

Gentle supports — such as visual cues, modeling, verbal reminders, or physical guidance — that are gradually reduced as your child gains independence.

SD – Discriminative Stimulus

A cue or instruction that signals that reinforcement is available (if you perform a specific behavior). For example, saying “touch your nose” prompts the child to respond, or seeing the McDonald’s Golden Arches that prompts you to drive in to get French fries.

Shaping

Teaching a new behavior by reinforcing small steps toward the desired behavior. For example, rewarding a child for saying part of a word before expecting the full word.

Generalization

When a child can use learned skills across different people, places, and situations. For example, saying “thank you” both at home and in school.

Understanding Assessment & Data Terms

ABC Data

Antecedent, Behavior, Consequence: A way of tracking what happens before, during, and after a behavior to understand patterns and context. Behavior is anything that a person is actively doing (i.e., running, hitting, laughing, talking).

Baseline Data

The “starting point” data gathered before therapy begins. It helps measure how much progress your child makes over time.

Frequency, Duration, and Latency

Frequency means how often a behavior occurs; Duration means how long it lasts; Latency means how quickly your child responds to a prompt. These data points may sound technical, but they help your therapy team make data-driven, compassionate decisions about what’s working best.

Autism-Specific Terms You’ll Hear Often

Stimming (Self-Stimulatory Behavior)

Repetitive movements or sounds (like flapping, humming, or rocking) that help regulate emotions or sensory input. Fun fact: we all “stim.” Twirling hair, jogging, knitting, painting, using a mantra- all of these are self-regulating and repetitive behaviors. Instead of “stopping” them, we can introduce additional self-regulation strategies to help someone self-soothe.

Sensory Processing

How a child’s brain interprets sounds, textures, lights, and movement. There are a total of 8 senses (not 5!), and some children are more sensitive (or sensory avoidant) while others seek more input (sensory seeking). Occupational therapists at Achieve Beyond specialize in helping families support sensory regulation in daily routines.

Meltdown vs. Tantrum

A tantrum is a set of behaviors that occur due to denied access to something, while a meltdown is an involuntary response to being overstimulated. Meltdowns are not “misbehavior” — they signal that a child’s nervous system needs calm and connection.

Echolalia

Repeating words or phrases heard from others. This may be a bridge toward spontaneous language and communication. Speech Therapists will assess a child and give strategies to help.

Joint Attention

When two people share focus on an object or event, like both looking at a ball or pointing at an airplane together. It’s a key foundation for social learning.

Therapy and Educational Support Services

Early Intervention (EI)

For children under age 3, Early Intervention provides family-centered services to address developmental needs early on. Achieve Beyond offers special instruction, ABA methodology instruction, speech therapy, occupational therapy, and physical therapy as part of our EI programs.

Committee for Pre School Education (CPSE)

For children aged 3-5, CPSE goes through the school district to help a child get the least restricted environment where they can learn and thrive academically in preschool.

IFSP – Individualized Family Service Plan

A family-centered plan for children under 3, focusing on both child development and family support goals.

IEP – Individualized Education Program

Once a child enters school (preschool or above), an IEP outlines specific educational goals and services to ensure progress in a supportive environment. Parents are equal members of this planning team but the plan focuses on the educational goals of the child.

Inclusion and Mainstreaming:

Including children with diverse abilities in general education classrooms promotes belonging, friendship, and shared learning.

Transition Planning

Preparing for next steps — such as moving from Early Intervention to preschool (CPSE), or from school-based services to adulthood. Achieve Beyond helps families navigate each stage with care and collaboration.

Communication and Language Support

AAC – Augmentative and Alternative Communication

Any tool that helps a child communicate beyond spoken words — including gestures, pictures, speech-generating devices, and sign language.

PECS – Picture Exchange Communication System

A visual system that teaches children to communicate by handing over pictures of what they want or need.

Expressive and Receptive Language

Expressive refers to what your child can say or communicate. Receptive refers to what your child can understand. Therapists target both to build meaningful, functional communication.

Manding

An ABA term used to describe a child requesting. This can be displayed through pointing or tapping what they want, signing, using a picture card, pulling a parent over to an item, or vocally requesting. Manding is the most important thing we can teach someone because it gets them access to the things, activities, and information they want (or what they want to stop), which increases communication and decreases challenging behavior.

Pragmatic Language

Using language for social interaction — taking turns, greeting others, and understanding humor or emotions in conversation.
