Bilingual English-Spanish Assessment™ (BESA™): Inventory to Assess Language Knowledge (ITLAK)

The Bilingual English-Spanish Assessment (BESA) was developed in response to the need for valid, reliable instruments for assessment of speech and language ability, along a continuum, in English-Spanish bilingual children ages 4 through 6 years.

The BESA is a comprehensive assessment of a child’s speech and language abilities in English and Spanish. Two ancillary questionnaires (BIOS and ITALK) can be used to document language exposure and use, allowing the examiner to develop a profile of any parent and teacher concerns. BESA subtests address the domains of phonology, morphosyntax, and semantics separately for both Spanish and English. There are three standardized and norm-referenced subtests addressing language ability, and one criterion-referenced activity allowing observation of pragmatic language. Administration time varies depending on whether or not both languages are tested and which subtests are included. Administration takes between one hour (for one language) and two hours (for both languages).

The BIOS is typically completed as part of an interview by the examiner. In this survey, parents are asked about the language exposure history of the child. This information helps the examiner know when and in what context each of the child’s two languages were used on a year-to-year basis. In addition, parents and teachers are asked what language the child hears and uses during a typical school day, and during a typical weekend day on an hour-by-hour basis. This information provides clinicians with information about relative use and exposure to each language and can help guide whether to test children in Spanish, English, or both. The parent survey (BIOS-Home) takes 10 to 15 minutes to complete; the teacher survey (BIOS-School) can be completed in 5 to 10 minutes.

The ITALK is completed by the examiner as a parent and teacher interview. The ITALK items address relative use of a child’s two languages and five areas of speech and language development in Spanish and English (vocabulary, grammar, sentence production, comprehension, and phonology). Parents and teachers are asked to identify the perceived level of the child's performance in each language. This inventory provides a brief indicator of relative language use. It also provides a description of parent and teacher concern and can be used to guide development of the assessment strategy. Results of the inventory can be...
