The Test of Word Finding-Third Edition (TWF-3) is a norm-referenced, single-word expressive language test designed to assess children’s word-finding abilities. The TWF-3 aids in identifying students who have word-finding problems, planning word-finding interventions, and measuring word-finding abilities in research studies.

The latest revision of the TWF-3 includes new normative data, new noun and verb targets, and a revised model of lexical processing. The Comprehension Check functions as a built-in assessment of a student's word knowledge. The TWF-3 contains both a standardized assessment and an informal assessment to aid clinicians in identifying children with word-finding problems. The standard and informal assessments are integral features of comprehensive word-finding assessments.

The TWF-3 includes three age- and grade-appropriate forms:

The standardized assessment of the TWF-3 combines 4 sections to form an overall Word-Finding Index:

The TWF-3 also provides five informal assessments that examine types of word-finding errors and contribute to interpreting the Word-Finding Index.

The TWF-3 has ample evidence of both reliability and validity. Internal consistency reliability exceeds .85, and test-retest coefficients for the Word-Finding Index exceed .80. Statistical analysis indicates the TWF-3 is able to accurately identify students with word-finding difficulties, as sensitivity is .86 and specificity is .78. An additional analysis of the TWF-3 shows there is no racial or gender bias.
