Designing the ideal test or series of tests to assess individuals who speak languages other than English is difficult. This article first describes some of the roadblocks—one of which is the lack of identification criteria for language and learning disabilities in monolingual and bilingual populations in most countries of the non-English-speaking world. This lag exists, in part, because access to general education is often limited. The second section describes tests that have been developed in the United States, primarily for Spanish-speaking individuals because they now represent the largest first-language majority in the United States (80% of English-language learners [ELLs] speak Spanish at home). We discuss tests developed for monolingual and bilingual English-Spanish speakers in the United States and divide this coverage into two parts: The first addresses assessment of students' first language (L1) and second language (L2), usually English, with different versions of the same test; the second describes assessment of L1 and L2 using the same version of the test, administered in the two languages. Examples of tests that fit a priori-determined criteria are briefly discussed throughout the article. Suggestions how to develop tests for speakers of languages other than English are also provided. In conclusion, we maintain that there will never be a perfect test or set of tests to adequately assess the communication skills of a bilingual individual. This is not surprising because we have yet to develop an ideal test or set of tests that fits monolingual Anglo speakers perfectly. Tests are tools, and the speech-language pathologist needs to know how to use those tools most effectively and equitably. The goal of this article is to provide such guidance.
