Subtests explained

WIAT-III UK for Teachers (WIAT-III UK-T) - Subtests explained


1. Early Reading Skills (new)

Age range: 4-8

Measures several areas deemed important for developing reading skills: naming letters, letter-sound correspondence (alphabetic principle), phonological awareness, and word reading comprehension. The student names letters of the alphabet, identifies and generates rhyming words, identifies words with the same beginning and ending sounds, blends sounds, matches sounds with letters and letter blends, and matches written words with pictures that illustrate their meaning.


2. Word Reading

Age range: 6-17+

Measures speed and accuracy of decontextualised word recognition. The student reads aloud from a list of words that increase in difficulty. The list of words is read without a time limit. The examiner records the student’s progress after 30 seconds and continues administration until the discontinue rule is met or the last item is administered.


3. Reading Comprehension

Age range: 6-17+

Measures untimed reading comprehension of various types of text, including fictional stories, informational text, advertisements, and how-to passages. The student may read passages aloud or silently. After each passage, the student orally responds to literal and inferential comprehension questions that are read aloud by the examiner.


4. Spelling

Age range: 5-17+

Measures written spelling of letter sounds and single words. The student hears each letter sound within the context of a word, and each word within the context of a sentence, and then the student writes the target letter sound or word.


5. Oral Reading Fluency (new)

Age range: 6-17+

Measures speed, accuracy, fluency, and prosody of contextualised oral reading. The student reads passages aloud, and then orally responds to comprehension questions after each passage. Fluency is calculated as the average number of words read correctly per minute. A qualitative scale is completed by the examiner to assess the student’s reading prosody. Comprehension questions are asked only to encourage reading for meaning; comprehension performance is not scored quantitatively.
