BILINGUAL SPECIAL EDUCATION EVALUATION OF CULTURALLY AND LINGUISTICALLY DIVERSE INDIVIDUALS

USING WOODCOCK TESTS

Criselda Guajardo Alvarado

Psycho-education evaluation of culturally and linguistically diverse students is a complex and often confusing undertaking that can intimidate even the most experienced evaluation professional. Until recent years a standardized bilingual evaluation was not possible because of a lack of test instruments in languages other than English. Within the last two decades however, more and more test batteries in other languages, especially Spanish, have been developed. These new test instruments have been warmly welcomed by professionals in the field hopeful that the advent of these tests will prove useful in conducting an appropriate and equitable evaluation of culturally and linguistically diverse students. The Woodcock tests include batteries in several languages and currently lead the field in bilingual psycho-educational evaluations. This document provides information examiners may need in order to conduct a bilingual evaluation and to help clarify some assessment issues related to the culturally and linguistically diverse population. Although this document focuses on evaluation issues of students bilingual in English and Spanish, a considerable amount of the information applies to students bilingual in English and other languages. The topics addressed are:

• general function and age range of the various English and Spanish Woodcock tests,

• special features in the English and Spanish cognitive batteries for testing individuals from bilingual backgrounds,

• special feature in the English and Spanish cognitive batteries for testing individuals with language deficiencies or language disabilities,

• interpretation considerations of test results for culturally and linguistically diverse students,

• co-normed and equated test batteries as they relate to culturally and linguistically diverse populations,

• fine points in assessing oral language proficiency and determining language dominance,

• discussion of the four basic steps in a bilingual psycho-educational evaluation, and

• bilingual cross-battery testing using Woodcock tests.

Woodcock Tests

The Woodcock tests provide a variety of assessment measures that can be utilized in bilingual evaluations. For appropriate selection of tests and their efficient use, the evaluation professional should be familiar with the available tests and their general function, language(s) of the test, age range, and assessment features specific for testing individuals from bilingual backgrounds. Table 1 lists the English and Spanish tests and provides some basic information for each test.
