Assessment, Instruction, and Intervention
Assessment, Instruction, and Intervention (Domain 4)
This domain tests data-based teaching: choosing assessments for a purpose, interpreting results correctly, and matching instruction and intervention to student need within a multi-tiered system.
Core rules
- Match the assessment to the purpose: screening identifies who may need support; diagnostic assessment pinpoints skill gaps; progress monitoring tracks response to intervention; outcome evaluation judges end-of-year or program results.
- Norm-referenced tests compare a student with a norm group; criterion-referenced tests compare performance with a standard or skill. Standard scores are not grade levels.
- Technical quality matters: reliability, validity, and fairness. A running record or miscue analysis describes reading behavior but is not a norm-referenced diagnostic test.
- MTSS/RtI tiers: Tier 1 is strong core instruction for all; Tier 2 is targeted small-group support; Tier 3 is intensive, individualized intervention. Decisions should be based on data, fidelity, and rate of progress.
- Effective intervention is explicit, systematic, scaffolded, and responsive, with modeling, guided practice, corrective feedback, and ample practice. Flexible grouping and culturally and linguistically responsive instruction matter.
- Accommodations change how a student learns or is assessed; modifications change what is taught or expected. Special education referral follows sustained inadequate response, not a single low score.
Worked example
A universal screener shows that 25% of second graders are below the oral reading fluency benchmark. The team should first examine Tier 1 core instruction and the screening data, not refer every child for special education. Students below benchmark receive Tier 2 small-group fluency instruction using repeated and echo reading, with progress monitoring every two to three weeks. If a student's progress remains flat after a reasonable trial with good fidelity, the team conducts diagnostic assessment and considers Tier 3 or a special education referral. Reasoning: screening flags risk; progress monitoring and diagnostic data determine need and next steps.
Traps
- Using a screener as a full diagnostic evaluation.
- Treating a standard score as a grade level or as proof of disability.
- Monitoring progress too infrequently or changing instruction before a fair trial.
- Confusing accommodations with modifications.
- Ignoring implementation fidelity when judging an intervention.
