| Basic decoding vs. comprehension discrepancy needed | ✅Basic Reading vs. Reading Comprehension & Fluency composites | ✅Sound-Symbol/Decoding vs. Reading Understanding clusters | ✅Basic Reading Skills vs. Reading Comprehension clusters | ✅ |
| Built-in rapid naming / naming speed | —No RAN measure; administer KTEA-3 ONF or CTOPP-2 separately | ✅Object Naming Facility (ONF) — rapid naming built inUnique | —No RAN; pair with CTOPP-2 | — |
| Written Language | ||||
| Graphomotor measure — alphabet writing fluency | ✅Alphabet Writing Fluency — letters written in 30 seconds; key for dysgraphia documentationOnly option | —No graphomotor measure; pair with WIAT-IV AWF if needed | — | — |
| Written expression / composition detail | ✅Sentence Composition + Essay Composition — detailed rubric; Sentence Writing Fluency; four WE subtests totalMost detail | ◑Written Expression subtest combines sentence and paragraph; less granular than WIAT-IV | ◑Writing Samples + Sentence Writing Fluency; Written Expression cluster; adequate for most evals | ◑Same WE structure; Spanish norms |
| Spelling and basic writing skills | ✅Spelling subtest; Spelling composite; error analysis available separately | ✅Spelling with built-in error analysis — error types identified automaticallyBuilt-in EA | ✅Spelling + Spelling Skills cluster; Spelling of Sounds for phoneme-grapheme | ✅ |
| Built-in error analysis across domains | —Available but requires additional scoring step; not built into administration | ✅Error analysis built into reading, spelling, and math — identified during administration without extra stepUnique | — | — |
| Mathematics | ||||
| Math fluency by operation (add, subtract, multiply separately) | ✅Math Fluency-Addition, Math Fluency-Subtraction, Math Fluency-Multiplication — three separate timed subtestsMost granular | ◑Math Fluency — single timed composite across all operations | ◑Math Facts Fluency — mixed operations, 3-minute timed; not separated by operation | ◑ |
| Number sense / early math foundations | ◑Numerical Operations covers basic number concepts; no dedicated number sense subtest | ◑Math Concepts & Applications covers early math; no dedicated number sense cluster | ✅Number Concepts cluster — Magnitude Comparison + Number Sense subtests; best early math foundation coverageBest coverage | ✅Same Number Concepts cluster; Spanish norms |
| Math reasoning vs. calculation discrepancy | ✅Math Problem Solving vs. Numerical Operations; Math composite | ✅Math Computation vs. Math Concepts & Applications clusters | ✅Math Calculation vs. Math Problem Solving clusters; strongest CHC-aligned split | ✅ |
| Oral Language | ||||
| Detailed oral language composites | ✅Oral Language, Listening Comprehension, Oral Expression composites; most granular OL coverageMost composites | ✅Oral Language, Oral Language Fluency, Listening Comprehension, Oral Expression; Associational Fluency built in | ◑Oral Language cluster in ACH; pair with WJ IV-OL for full oral language profile | ◑OL cluster; pair with WMLS-R for language dominance and fuller OL picture |
| Battery Pairing & Selection Factors | ||||
| Student is Spanish-dominant EB | —U.S. English norms; not appropriate as primary for Spanish-dominant EB | —U.S. English norms; not appropriate as primary | —English norms only; use Batería IV ACH instead | ✅Normed on Spanish-speaking population; designed to pair with Batería IV COG for a complete Spanish-language evalOnly Spanish-normed option |
| Using WISC-V as cognitive battery | ✅Co-normed with WISC-V (Pearson); ability-achievement comparisons are standardized and defensibleSame publisher | ◑Cross-battery ability-achievement comparison possible but not co-normed | ◑Cross-battery comparison possible; CHC alignment strong but not co-normed | — |
| Using KABC-II as cognitive battery | ◑Cross-battery comparison possible; different publishers | ✅Co-normed with KABC-II (Pearson); standardized ability-achievement comparisonsSame publisher | ◑CHC alignment good; cross-battery interpretation needed | — |
| Using WJ-V COG as cognitive battery | ◑Different publisher; cross-battery comparison requires C-SEP/XBA approach | —Different publisher; not recommended as primary pair | ✅Same battery family; ability-achievement clusters directly comparable; strongest CHC alignmentSame family | ◑Pair Batería IV COG + Batería IV ACH for full Spanish eval; WJ-V COG + Batería IV ACH is cross-battery |
| Ages 4–5 / early childhood SLD screening | ✅Norms start at 4:0; pre-academic subtests appropriate for young children | ✅Norms start at 4:0; similar EC coverage | ✅Norms start at 2:0; broadest early childhood age coverage | ✅Norms start at 2:0 |
| Efficient cross-domain coverage in one battery | ◑17 subtests; good domain coverage but no phonological processing or RAN built in | ✅19+ subtests covering academic + phonological + oral language + RAN — most efficient single-battery optionMost efficient | ✅Standard battery covers all academic domains; extended subtests add depth; WJ-V COG adds ability-achievement without switching publishers | ✅ |
| Post-secondary / adult evaluation (age 18+) | ✅Norms extend through age 50:11Adult norms | ◑Norms through 25:11; appropriate for most transition-age evals | ✅Norms to age 90+; broadest lifespan coverage | ✅Norms to 90+ |
