OSAT OK085 · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Understanding Students with Disabilities

  • Define each of the thirteen IDEA disability categories and match a one-sentence classroom scenario to the correct category.

  • Distinguish the defining features of specific learning disability, emotional disturbance, and intellectual disability in a written comparison table.

  • Explain the difference between the medical and educational definitions of disability as used in eligibility decisions.

  • Identify the legal entitlements (FAPE, LRE, due process) that frame how schools serve students with disabilities.

Your checkpoint

A one-page categorical reference sheet covering all IDEA categories with a matching practice set of 20 scenarios scored at 90% or better.

Week 2

Understanding Students with Disabilities

  • Describe the characteristics and instructional implications of autism spectrum disorder, ADHD, and speech-language impairment.

  • Compare the needs of students with sensory impairments (deaf/hard of hearing, visual impairment) to those with physical or health disabilities.

  • Analyze how second-language acquisition and cultural background can be mistaken for disability, and explain the exclusionary factors in eligibility.

  • Summarize the principles of universal design for learning and how they reduce barriers for students with disabilities.

Your checkpoint

Three case-study write-ups (one per cluster: high-incidence, sensory/physical, culturally and linguistically diverse) each identifying the likely disability, supporting evidence, and two instructional accommodations.

Week 3

Assessing Students with Disabilities and Developing Individualized Education Programs

  • Sequence the referral, evaluation, eligibility, and IEP development steps and state the legal timeline for each.

  • Explain the purpose and components of a comprehensive evaluation, including the role of standardized and curriculum-based measures.

  • Interpret standard scores, percentile ranks, and confidence intervals and describe how they inform eligibility and goal writing.

  • Identify the required members of an IEP team and the role each plays in the process.

Your checkpoint

A process flowchart of the special education referral-to-IEP cycle with statutory timelines annotated, plus a glossary of 15 assessment terms with worked score interpretations.

Week 4

Assessing Students with Disabilities and Developing Individualized Education Programs

  • Draft measurable annual goals containing a baseline, target behavior, criterion, and method of progress monitoring.

  • Differentiate present levels of academic achievement and functional performance from goals and from accommodations.

  • Construct a transition plan for a student age 16 or older that includes measurable postsecondary goals and coordinated services.

  • Explain procedural safeguards, prior written notice, and the parent's right to disagree with the school's evaluation.

Your checkpoint

A full mock IEP for a fictional student: present levels, three measurable annual goals, accommodations, service minutes, and a transition section, self-checked against a rubric.

Week 5

Promoting Development and Learning for Students with Disabilities

  • Apply evidence-based reading interventions (explicit phonics, fluency practice, comprehension strategy instruction) to a struggling reader profile.

  • Design scaffolded math instruction that addresses computation and problem-solving for students with learning disabilities.

  • Describe positive behavioral interventions and supports across tier 1, 2, and 3 and write a functional behavior assessment summary with a behavior intervention plan.

  • Explain how assistive technology and accessible materials support access to the general curriculum.

Your checkpoint

A three-lesson intervention unit (reading, math, behavior) with explicit instructional steps, scaffolds, and a progress-monitoring plan for each.

Week 6

Promoting Development and Learning for Students with Disabilities

  • Compare co-teaching models and select the appropriate model for a given classroom scenario.

  • Differentiate instruction by content, process, and product for a mixed-ability inclusive classroom.

  • Describe social-emotional and self-determination supports that build independence for students with disabilities.

  • Explain how to monitor progress and adjust intervention intensity based on data.

Your checkpoint

A differentiated lesson plan for an inclusive classroom that specifies the co-teaching model, three tiers of support, and a data-collection tool with decision rules.

Week 7

Working in a Collaborative Learning Community

  • Describe effective communication strategies for collaborating with families, including culturally responsive conferencing.

  • Outline the roles and shared responsibilities of general educators, special educators, related service providers, and paraprofessionals.

  • Explain how to run an IEP meeting that stays student-centered and resolves disagreement constructively.

  • Identify professional ethics, confidentiality requirements, and mandated reporting obligations for educators.

Your checkpoint

A collaboration toolkit: a parent conference script, an IEP meeting agenda, and a roles-and-responsibilities matrix, each reviewed against confidentiality and ethics guidelines.

Week 8

Understanding Students with Disabilities & Assessing Students with Disabilities and Developing Individualized Education Programs & Promoting Development and Learning for Students with Disabilities & Working in a Collaborative Learning Community

  • Synthesize all four domains into a single concept map linking disability characteristics, assessment, instruction, and collaboration.

  • Complete two timed full-length practice tests and analyze wrong answers by domain to find remaining gaps.

  • Re-drill the two weakest domains using targeted flashcards and scenario questions until accuracy exceeds 85%.

  • Practice constructed-response answers that integrate assessment data with instructional decisions.

Your checkpoint

A scored practice-test log showing domain-by-domain accuracy, a list of the five weakest subareas with corrections, and two polished constructed responses.

Milestones

Week 2: Score at least 85% on a 25-question self-made quiz covering the characteristics and eligibility factors in Domain 1.

Week 4: Complete the mock IEP with every required component present and at least three goals rated measurable on the rubric.

Week 6: Teach back the intervention unit to a study partner or record a 10-minute explanation, confirming all scaffolds and monitoring steps are defensible.

Week 8: Achieve 80% or higher on both timed practice tests with no domain below 70%, and finish the weak-area correction log.
