The role of a Behavior Interventionist (BI) is a recognized entry point for individuals seeking to contribute to behavioral health. This career path offers a chance to work directly with clients to foster positive change and skill development. Understanding the function, daily duties, and necessary qualifications provides a clear roadmap for those interested in joining this growing profession.
Defining the Behavior Interventionist Role
A Behavior Interventionist is a trained paraprofessional who works under the direct supervision of a licensed clinician, typically a Board Certified Behavior Analyst (BCBA). The BI delivers individualized behavioral treatment to clients as outlined in a comprehensive plan, rooted in the principles of Applied Behavior Analysis (ABA). The core objective is to decrease challenging behaviors, such as aggression or self-injury, while simultaneously increasing adaptive skills like communication, social interaction, and daily living abilities. BIs apply evidence-based strategies to create a structured environment that promotes learning and generalization of new skills.
Primary Responsibilities and Daily Tasks
The daily work of a Behavior Interventionist centers on the implementation of a client’s Behavior Intervention Plan (BIP). This involves using specific, highly structured teaching methods designed to target individual skill deficits and behavioral excesses. For instance, the BI may use Discrete Trial Training (DTT), which breaks down complex skills into small steps, providing immediate feedback and reinforcement.
Another approach is Natural Environment Teaching (NET), which embeds learning opportunities within the client’s play or daily routines to promote skill generalization in real-world contexts. A large portion of the day is dedicated to data collection, where the interventionist precisely records the frequency, duration, or intensity of target behaviors and skill responses. The BI must also model appropriate social and communication skills, working to replace maladaptive behaviors with functional equivalents, such as teaching a child to use a picture exchange system instead of engaging in a tantrum.
Common Work Settings
Behavior Interventionists provide services across various environments to ensure skills learned can be applied elsewhere. A common setting is the client’s private home, where interventionists work directly with the family to integrate strategies into daily routines and train parents or caregivers.
BIs also work as aides or paraprofessionals within school systems, assisting students in general or special education classrooms. Specialized clinics and treatment centers employ interventionists to deliver intensive, one-on-one therapy. The role often requires the BI to work in community environments, such as parks, stores, or doctor’s offices, to practice skills like waiting in line or engaging in social greetings.
The Populations Served
The clientele for Behavior Interventionist services are individuals who exhibit behavioral difficulties or developmental delays that interfere with daily functioning and learning. Children and adolescents with Autism Spectrum Disorder (ASD) represent the largest population served, as ABA-based intervention is recognized as an effective treatment. Interventionists assist these individuals in acquiring language, social, and self-help skills.
Services also extend to individuals with other diagnoses, including Attention-Deficit/Hyperactivity Disorder (ADHD), intellectual and developmental disabilities, and various emotional or behavioral disorders. The interventionist’s support is tailored to address the unique needs of each person, focusing on behavior reduction and skill acquisition. The goal is to increase independence and improve the overall quality of life for the client and their family.
Required Education and Certifications
Entry-level Behavior Interventionist positions require a minimum of a high school diploma or equivalent, though many employers prefer candidates with college coursework or an associate’s degree. A bachelor’s degree in psychology, education, or social work is viewed favorably and may be required for higher-paying roles. All candidates must successfully pass a comprehensive state and federal background check, including fingerprinting, due to working with vulnerable populations.
The job title “Behavior Interventionist” does not have a single national certification, but employers mandate substantial initial training. This training covers the fundamentals of ABA, data collection procedures, and specific intervention techniques. New hires frequently undergo 20 to 40 hours of training before working independently, which may include instruction on safety procedures like crisis intervention. State-specific requirements vary, with some states having their own certification or registry for paraprofessionals.
Distinguishing the Behavior Interventionist from Related Roles
Understanding the professional hierarchy distinguishes the Behavior Interventionist (BI) from the Registered Behavior Technician (RBT) and the Board Certified Behavior Analyst (BCBA). BI is typically a job title assigned by an employer for a person who implements behavioral treatment. Conversely, the RBT is a standardized, paraprofessional certification granted by the Behavior Analyst Certification Board (BACB) after completing a 40-hour training course, a competency assessment, and an examination.
Many BIs pursue the RBT credential because it demonstrates a standardized level of competency, often leading to higher pay or increased job opportunities. The BCBA occupies the top tier, possessing a master’s degree and extensive supervised experience, allowing them to conduct complex behavioral assessments and design treatment plans. BIs and RBTs operate exclusively under the BCBA’s supervision, carrying out the prescribed intervention programs.
Career Outlook and Impact
The career outlook for Behavior Interventionists is strong due to the increasing recognition and demand for ABA services, particularly for individuals with ASD. Job growth is expected to remain strong as insurance coverage expands and awareness of developmental disabilities increases. Entry-level salaries for BIs typically range from $36,000 to $45,000 annually, varying based on location, education, and RBT certification status.
Experienced interventionists, especially those in high-cost-of-living areas or with specialized skills, can earn upwards of $60,000 to $80,000. The role provides professional rewards through direct observation of client progress and skill acquisition. The experience gained as a BI or RBT is a clear pathway for professional advancement, providing the foundational clinical exposure necessary for those who wish to pursue a degree to become a BCBA.
