EIBI/ABA Services

NOCS provides a variety of services within home, school, and community settings. Our professionals are committed to working with the individual’s support team to identify the successes and barriers to reaching full potential.

ABA stands for Applied Behaviour Analysis. Technically, Applied Behavior Analysis is a scientific approach for discovering environmental variables that reliably influence socially significant behaviors and for developing a technology of behavior change that is practical and applicable (Cooper, Heron, Heward, 2007).


In other words, ABA is the study of the back-and-forth interactions between a person and their environment.
All ABA interventions are defined by the 7 core dimensions, as outlined by Baer, Wolf, and Risley (1968) in the first edition of the Journal of Applied Behavior Analysis:


  • Generality: Behaviour change is durable over time and across a wide variety of contexts.
  • Effective: Intervention has a practical effect on the behaviour it seeks to change.
  • Technological: Intervention is described clearly and concisely so others may implement the procedures accurately.
  • Applied: Behaviour change is meaningful to the individual and those closest to them (e.g., parents, siblings, peers, etc.).
  • Conceptually Systematic: Interventions are consistent with research-based principles of behaviour change.
  • Analytical: Treatment decisions are data-driven, based on meaningful measures of change.
  • Behavioural: Behaviours are defined in ways that can be observable and measurable.

EIBI stands for Early Intensive Behaviour Intervention. It is a specific form of behavioural intervention that is highly structured and rooted in principles of ABA. Research has identified learners under the age of 6 experience greater impact with this mode of treatment as compared to older learners. The core elements of EIBI involve:

  • Specific teaching procedures (i.e., discrete trial training)
  • Use of a 1:1 teaching ratio in the early stages of treatment
  • Implementation of treatment for 20-40 hours per week (see Comprehensive services below) for 1 to 4 years
  • Supervision from an ABA-trained clinician (BCBA/BCaBA)
  • Systematic progression through comprehensive developmental skills curricula

NOCS offers 5 different models of ABA service delivery, differentiated by the level of treatment intensity necessary to make meaningful change. (Can these be clicked on then the information appears.)

  1. Skill Development: Treatment is developed to teach 1-2 specific skills. Typically, this requires the lowest level of intensity in relation to treatment hours (i.e., 3hrs/week), but more participation from the learner’s support team to maintain ongoing skill acquisition.
  2. Focused: Treatment is developed to target 2-3 developmental domains (e.g., language, social skills, challenging behaviour, etc.). This is considered a moderate intensity of treatment hours (i.e., 6-15hrs/week), with a 6 month service delivery model that includes assessment, treatment, generalization, and maintenance phases. These programs can be delivered in a 1:1 or small group setting. Participation from the learner’s support team is essential in the last phases of service to ensure sustainable behaviour change.
  3. Comprehensive: Treatment is developed using curricula that addresses multiple developmental domains (e.g., communication, play, adaptive, social, academic, etc.). Often, behaviour reduction programming is necessary to address challenging behaviours and facilitate learning availability. This is considered a high intensity model of treatment (i.e., 20-30hrs/week), with a minimum 6-month service delivery model. These programs are initially delivered in a 1:1 environment and may eventually move to small-group settings. Caregiver participation is encouraged throughout the intervention to support with application of newly learned skills outside of treatment contexts.
  4. Challenging Behaviour Assessment and Intervention: This service is geared toward addressing those behaviours that significantly impact the learner’s day-to-day functioning. Assessment aims to understand ‘why’ challenging behaviour is occurring, and what skills need to be taught to reduce the need for the challenging behaivours to occur. The focus of this approach is to stabilize the environmental response and minimize the risk to self or others. A personalized analysis of problem behaviours is designed to inform socially meaningful treatment plans.
  5. Consultation/Caregiver Training: This service allows for up to 3 consultative meetings with a BCBA to discuss general behaviour strategies on specific skills or problem behaviours. There is no commitment to a formal assessment or treatment plan and direct therapy is not provided.

Northern Outreach and Clinical Services (NOCS) believes in teaching individual’s skills in the environment they’re expected to use their skills. Through a family-centred approach, we work in partnership with families to better understand their circumstances and assist caregivers with treatment planning needs. Under the supervision of a Board-Certified Behaviour Analyst (BCBA), ABA Therapists are extensively trained to provide direct services to children, youth and their families using evidence-based ABA principals.
