WIAT-III, KTEA-3, and WJ IV Achievement Test Comparison
Reading Skills Assessment
WIAT-III Reading Subtests
- Early Reading Skills
- Reading Comprehension
- Word Reading (Equivalent to Letter and Word Recognition on KTEA-3)
- Pseudoword Decoding (Nonsense Words)
- Oral Reading Fluency
WIAT-III vs. KTEA-3 Reading Comparison
- Instructions are presented in a book rather than on the back side of the easel.
- Age Ranges: KTEA-3 (4–25 years); WIAT-III (4 years – 19 years 11 months).
WJ IV Achievement Reading Subtests
- Letter and Word Recognition (Identify and read letters and words)
- Passage Comprehension (Read words and identify pictures or complete sentences)
- Word Attack (Read nonsense words)
- Phonological Awareness (Identify pictures/letters that begin with a specific sound)
- Sentence Reading Fluency (Read questions and circle yes or no)
WJ IV vs. KTEA-3 Reading Comparison
- Word Attack (WJ IV) is equivalent to Nonsense Words (KTEA-3), though the name differs.
- Letter and Word Recognition is consistent across both tests.
- Both assessments measure phonological awareness and nonsense word decoding.
- Scoring for many items is binary (1 or 0).
- Basal and ceiling rules are established differently.
Writing Skills Assessment
WIAT-III Writing Subtests
Alphabet Writing Fluency, Sentence Composition.
WIAT-III vs. KTEA-3 Writing Comparison
- Only Writing Fluency is common between the two tests.
- Scoring for fluency is similar (0, 1, or 2 points based on the student’s response).
- The WIAT-III provides extra credit (contributing to the raw score) that the KTEA-3 does not.
- WIAT-III uses single-word prompts for writing fluency, similar to the KTEA-3 picture prompt.
- KTEA-3 includes Written Expression and Spelling, which the WIAT-III does not.
- The KTEA-3 Spelling subtest is conceptually similar to the WIAT-III Alphabet Writing subtest.
WJ IV Achievement Writing Subtests
- Spelling (Writing words presented orally)
- Writing Samples (Measures skill in writing responses to various items)
- Sentence Writing Fluency (Writing simple sentences quickly and quietly)
WJ IV vs. KTEA-3 Writing Comparison
The layout of the items is similar, and both tests include a measure of Sentence Writing Fluency.
Mathematics Skills Assessment
WIAT-III Mathematics Subtests
- Math Problem Solving
- Numerical Operations
- Math Fluency (Addition, Subtraction, and Multiplication)
Students are required to identify objects, count, identify numbers, interpret graphs, and solve problems within a response booklet.
WIAT-III vs. KTEA-3 Mathematics Comparison
- Both utilize a response booklet for students to solve math problems.
- The directions are not located in the flipbook (easel).
- Both employ basal and discontinue rules.
- Specific scoring notations are required: Circle “DK” for “don’t know,” “0” for incorrect, and “Y” if the student uses paper or pencil.
WJ IV Mathematics Subtests
- Applied Problems
- Calculation (Math Computation)
- Math Facts Fluency
- Number Matrices
WJ IV vs. KTEA-3 Mathematics Comparison
- Both tests cover similar content areas: Math Computation, Math Fluency, and Math Concepts and Applications.
- Both require an examiner script and manual.
- Subtests are often called different names despite similar content.
- The KTEA-3 does not include the Number Matrices subtest.
Oral Language and Fluency Assessment
WIAT-III Oral Language Subtests
- Oral Language
- Oral Listening Comprehension
- Oral Discourse Comprehension
WIAT-III vs. KTEA-3 Fluency Comparison
Both tests include similar fluency measures, specifically Word Recognition Fluency and Decoding Fluency.
WJ IV Fluency Subtests
Reading Fluency.
WJ IV vs. KTEA-3 Fluency Comparison
Both tests include measures of Word Recognition Fluency and Decoding Fluency.
