Reading Assessment and Instruction
What the domain tests
Reading Assessment and Instruction tests your ability to choose, interpret, and use assessments to plan instruction. It covers screening, diagnosis, progress monitoring, and outcome measures; reliability and validity; and instructional approaches such as structured literacy, explicit and systematic phonics, differentiated groups, and MTSS/RTI tiers.
Core rules
- Purpose drives assessment. Screening identifies students at risk; diagnostic assessment pinpoints specific strengths and needs; progress monitoring checks response to instruction over time; outcome assessment evaluates program effectiveness.
- Reliability means consistency; validity means the test measures what it claims. A score is an estimate, not a precise truth. Percentile ranks compare a student with peers; grade equivalents can mislead because they are not equal-interval.
- Curriculum-based measurement (CBM), such as oral reading fluency, is standardized, brief, and repeatable. Running records and informal reading inventories provide diagnostic detail but are not interchangeable with CBM.
- Use multiple sources: a single score should not determine placement or intervention.
- Structured literacy is explicit, systematic, cumulative, and diagnostic. It teaches phonology, sound-symbol correspondence, syllables, morphology, syntax, and semantics.
- MTSS/RTI uses tiered support: Tier 1 core instruction, Tier 2 targeted small-group intervention, Tier 3 intensive individualized support. Progress monitoring determines whether a student moves between tiers.
Worked example
A second grader reads a grade-level passage at 88% accuracy, 20 words correct per minute, and answers 2 of 5 comprehension questions correctly. The teacher first checks fluency and decoding rather than starting a comprehension-only intervention. The accuracy and rate suggest inaccurate, labored word reading; a diagnostic phonics assessment shows difficulty with vowel teams and multisyllabic words. The plan: explicit vowel-team instruction, word building, repeated reading with feedback, and progress monitoring every two weeks. Comprehension is addressed through vocabulary and text discussion once decoding improves.
Traps
Treating a screening score as a diagnosis; using grade-equivalent scores as precise; changing instruction without a baseline; monitoring too infrequently; assuming a comprehension problem when fluency or decoding is the bottleneck; and confusing Tier 2 with special education.
