TWF-3 is a nationally standardized, individually administered, diagnostic tool for the assessment of learners’ Word Finding skills. The TWF-3 was developed to be administered to learners 4 years 6 months through 12 years 11 months. Three forms are provided: a pre-primary form for preschool and kindergarten students; a primary form for the first and second grades; and an intermediate form for the third through sixth grades. Learners’ are asked to retrieve nouns and verbs on picture naming and sentence naming tasks. An accuracy index and percentile rank are obtained for each learner.
Using the TWF-3, examiners carry out a differential diagnosis of semantic and phonological based word finding error patterns. Three word finding error patterns are considered, Error Pattern 1, Lemma related semantic errors; Error Pattern 2, Form related blocked errors, and Error Pattern 3, Form and segment related phonologic errors. Naming accuracy is measured on noun naming, verb naming and category naming tasks. Knowledge of erred target words is measured using the TWF-3 comprehension assessment. Responsiveness to phonemic cueing is measured using the phonemic cueing procedure. Oral motor skills are checked using a repetition task for each erred multisyllabic word. Target word substitutions are classified as to their semantic and phonological based attributes and secondary characteristics of word finding difficulties are tallied. The TWF-3 is designed to identify learners who have word-finding difficulties, plan word finding intervention, and measure word finding ability in research studies.
