Test of Early Grammatical Impairment : TEGI - Free Product from University of Kansas
The Rice/Wexler Test of Early Grammatical Impairment (TEGI) is an individually administered clinical tool that can be used for the identification, diagnosis, screening, and follow-up evaluation of grammatical deficits in young children, ages 3 through 8 years, who speak Standard American English (SAE). The test focuses on a particular area of grammar that is known to be difficult for young children with language impairment at the age that this grammatical competence becomes well established in children with normal language acquisition.
Advantages of Using Rice/Wexler Compared to Other Language Measures In addition to the robust psychometric properties of the test:
1. Its focus on finiteness is conceptually sound in terms of the linguistic properties of adult grammar.
2. Performance on the test can be directly interpreted as describing fundamental properties of what a child knows about grammar.
3. Performance on the test can be interpreted in terms of a child’s progress toward the adult grammar.
4. The test focuses on a property of English grammar that is known to be well mastered by children before they enter school.
5. It focuses on a property of grammar that is known to be difficult for children with language impairments.
6. It can identify affected children whose sole developmental deficit is language impairment, such as children with Specific Language Impairment (SLI).
7. It is well suited to identify children of school-entry age who need early intervention.
8. It has high levels of sensitivity and specificity, leading to accurate identification of affected children, without a high rate of false identification of unaffected children.
