Core topics
Modules & lessons
Work top to bottom — every lesson has an objective, curated resources, a hands-on lab, and a self-check.
Module 1 · Foundations Beginner 4 lessons ›
Developmental Disabilities: An Overview
🎯 Describe major conditions respectfully.Developmental disabilities include intellectual disability, autism spectrum disorder, Down syndrome, cerebral palsy, and fetal alcohol spectrum disorder. The social model says disability lives in barriers, not people. Language matters: person-first, strengths-based, and never the R-word — how we talk shapes how we support.
✍️ Self-check question
What is the difference between the medical and social models of disability?
Person-Directed Planning & Rights
🎯 Put the person at the centre of every plan.People with developmental disabilities have the same rights as everyone: choice, relationships, risk, and dignity. Person-directed planning asks: what is important TO the person (joy, connection) and FOR them (health, safety) — then balances both. Ontario's QAM and agency plans formalize goals the PERSON chose.
✍️ Self-check question
What is the difference between important TO and important FOR?
Communication & AAC
🎯 Support every style of communication.Many people communicate beyond speech: gestures, pictures (PECS), sign, and devices (AAC). Total communication means using all of it, speaking at the person's pace, waiting 10 seconds for responses, and confirming meaning rather than guessing. Presume competence — understanding often far exceeds expression.
✍️ Self-check question
Why presume competence even when a person does not speak?
Daily Living Support & Dignity
🎯 Teach skills while preserving dignity.Skill-building uses task analysis: break the skill into steps, teach with the least prompt needed (verbal → gesture → hand-over-hand), and fade prompts fast. Dignity rules: age-appropriate everything (no baby talk to adults), privacy in personal care, and choices all day — what to wear, eat, do.
✍️ Self-check question
What is the least-to-most prompting hierarchy and why fade quickly?
Module 2 · Behaviour, Health & Inclusion Intermediate 4 lessons ›
Positive Behaviour Support
🎯 Respond to behaviour as communication.Behaviour is communication: escape, attention, sensory, or tangible needs. Positive Behaviour Support finds the function (A-B-C: Antecedent, Behaviour, Consequence), then teaches a replacement skill and redesigns the environment. Reactive strategies keep everyone safe — but prevention and skill-building do the real work.
✍️ Self-check question
Why does punishing a behaviour without teaching a replacement fail?
Health, Medication & Seizure Awareness
🎯 Support health needs within your role.DSWs support health daily: medication assistance under agency protocol (right person, drug, dose, time, route — and document), seizure response (protect the head, time it, never restrain or put anything in the mouth), and recognizing illness in people who may not say 'it hurts'. Report changes — behaviour shifts often signal pain.
✍️ Self-check question
List three non-verbal signs that a person may be in pain.
Community Inclusion & Relationships
🎯 Build real belonging, not just presence.Inclusion is more than being in the community — it is being known, missed, and contributing. Support people to join real groups (gyms, faith communities, clubs) around their interests, facilitate introductions, then step back. Friendships and roles (volunteer, teammate, neighbour) are the strongest safety net a person can have.
✍️ Self-check question
What is the difference between presence, participation, and belonging?
Supported Employment & Day Programs
🎯 Coach people toward meaningful work.Real work for real pay is the goal: job carving matches tasks to strengths, job coaching teaches on-site then fades, and employers get support, not charity appeals. Day programs build skills and community when jobs are not yet the fit. Document progress with data — coaching plans live and die on task data.
✍️ Self-check question
Why does a good job coach plan to become unnecessary?
Module 3 · Professional Practice Professional 4 lessons ›
Abuse Prevention & Safe Support
🎯 Recognize, respond to, and report abuse.People with developmental disabilities face abuse at far higher rates — often from people they depend on. Know the signs (physical, behavioural, financial), respond with belief and calm, and report per law and agency policy immediately. Prevention is culture: open communication, choice, and zero tolerance for secrecy.
✍️ Self-check question
Why are people with communication barriers at higher abuse risk?
Documentation & Individual Support Plans
🎯 Write plans and notes that drive good support.Support plans translate the person's goals into strategies: what to do, how, and how we will know it works. Daily notes record facts, progress data, and health observations. Annual reviews measure outcomes the PERSON cares about. Write so a brand-new staff member could support well on their first shift.
✍️ Self-check question
What makes a support strategy usable by a new worker on day one?
Working with Families & Teams
🎯 Partner across a person's whole network.Families are lifelong experts and advocates — engage them as partners, share information per consent, and respect that goals may differ (then negotiate around the person's voice). Interdisciplinary teams (OT, SLP, behaviour therapists) give strategies; your daily logs tell them what actually works.
✍️ Self-check question
When family and team goals conflict, whose voice centres the decision?
Career Launch: DSW Interviews
🎯 Win a developmental-services position.Employers: Community Living agencies, school boards (EA roles), respite providers, day programs. Interviews test values more than knowledge — expect scenarios on choice vs safety, behaviour, and dignity. Bring: vulnerable-sector check, First Aid/CPR, and placement stories showing patience, creativity, and respect.
✍️ Self-check question
In the classic 'choice vs safety' scenario, what balance do interviewers want to hear?
