Reading Assessment and Instruction: Choosing Measures and Acting on Data
What the domain asks
Assessment items test whether you can choose the right instrument for a purpose and act on the results. Screening identifies students at risk (brief, predictive, administered to all). Diagnostic assessment pinpoints specific skill gaps. Progress monitoring is brief, repeated, and sensitive to short-term change (often weekly or biweekly, e.g., oral reading fluency or a phonics inventory). Outcome or summative measures judge end-of-year or program effectiveness. Formative assessment happens inside instruction.
Know norm-referenced versus criterion-referenced scores, reliability (consistency) and validity (measuring what is claimed), and formats: running records and miscue analysis (semantic, syntactic, graphophonic cues), informal reading inventories, cloze, curriculum-based measurement, spelling inventories, and phonological-awareness screeners. Dyslexia indicators-persistent word-level difficulty despite adequate instruction-call for targeted systematic intervention and referral, not retention.
Traps
- Reading grade-equivalent scores as "a fifth grader should score 5.0"; they are comparison points, not expectations.
- Confusing screening (who is at risk) with diagnostic assessment (what exactly is wrong).
- Treating oral reading fluency as a direct measure of comprehension; it is a proxy.
- Ignoring accuracy and text level when interpreting reading rate.
- Relying on a single measure; triangulate across data sources.
Worked example
A second grader reads 55 correct words per minute at 98% accuracy on grade-level text but answers 2 of 8 questions correctly. Accuracy and rate are adequate for the level, so the data point to language comprehension. The response is to build vocabulary and background knowledge through text-dependent questions and structured retelling, while continuing progress monitoring to verify the change.
