Word Analysis and Fluency
What this domain tests
Items probe the English orthographic system and how children learn to decode it automatically: phonics scope and sequence, syllable types and division, morphology, high-frequency word learning, and fluency (accuracy, rate, prosody).
Orthography and phonics
- About 44 phonemes are represented by 26 letters, singly and in combinations: consonant digraphs (sh, ch, th), blends (bl, str), vowel teams (ai, ee, oa), diphthongs (oi, ou), r-controlled vowels, silent-e, and schwa in unaccented syllables.
- The six syllable types: closed, open, vowel-consonant-e, vowel team, r-controlled, consonant-le. Division patterns: VC/CV (rab-bit), V/CV (o-pen), VC/V (cam-el), and stable final syllables.
- Systematic synthetic phonics (part-to-whole) outperforms incidental or analytic approaches for at-risk readers; the National Reading Panel found systematic phonics improves decoding and spelling.
- Orthographic mapping (Ehri): readers bond graphemes to phonemes to store words for instant retrieval. "Sight vocabulary" is a product of mapping, not shape memorization - even irregular words are taught by analyzing their regular parts.
Fluency
Fluency = accuracy + rate + prosody, and it mediates comprehension. Instruction includes modeled reading, echo and choral reading, repeated reading, partner reading, and performance. Measure oral reading fluency in correct words per minute against grade-level benchmarks, and listen for phrasing; rate without prosody is not fluency.
Worked example
A second grader reads hop and cap correctly but reads hope as "hop" and cape as "cap." Reasoning: the error pattern is specific to vowel-consonant-e, not general decoding delay. The targeted move is a word sort contrasting CVC and CVCe with sound-by-sound blending, then transfer to connected text containing the pattern.
Traps
Treating blends and digraphs as identical; drilling sight words as unanalyzed wholes; pushing rate before accuracy is secure; using frustration-level text for timed readings; applying syllable rules as absolutes when English has exceptions.
