Program details
Overview
If you want to work in the growing and highly specialized field of applied behaviour analysis, the Behavioural Science program is where you want to be. For over four decades, the Behavioural Science program has trained students to work front-line with a wide range of client populations in a variety of areas within the human services field. Students are taught how to develop and implement behavioural interventions to teach skills to clients and/or reduce challenging behaviours. Students interested in this program should have a strong desire to work with populations who present with complex behavioural, cognitive, emotional and/or psychological issues. They should also be comfortable working with any population that presents with disruptive behaviours and/or intellectual challenges. Students coming to the program need to be prepared to complete practicum placements working with any of the client populations listed below under career opportunities. Our program trains students in specific treatment options that can be applied to work with any individual who presents with challenges rather than preparing students to work with only one or a specific client population.
Requirements
Admission Requirements: St. Lawrence College's Behavioural Science advanced diploma requires an Ontario Secondary School Diploma (OSSD) with the majority of Grade 11 and 12 courses at the C, U or M level, including Grade 12 English at the C or U level, Grade 11 Math at the C, U or M level (Grade 12 Math recommended), and one of Grade 11 or 12 Chemistry, Biology, Physics or Science at the C, U or M level. The program page names its own international 'Proof Of English Proficiency' requirement without stating scores. The program page does not state its own language-proficiency scores; applicants whose first language is not English are assessed against St. Lawrence College's institution-wide scale for Certificate, Diploma and Advanced Diploma programs: IELTS Academic 6.0 overall (no band below 5.5), TOEFL iBT 4 overall (78 under the pre-January-2026 scale), PTE Academic 55, CAEL 60, or Duolingo 110 (no sub-score below 85). A Criminal Background Check and immunization documentation are required as conditions of field placement, not of admission.
