Dr. Guillermo Solano-Flores specializes in educational measurement, assessment development, and the linguistic and cultural issues that are relevant to both the testing of linguistic minorities and international test comparisons. He is Full Professor of Bilingual Education and English as a Second Language at the School of Education of the University of Colorado at Boulder. A psychometrician by formal training, his work focuses on the development of alternative, multidisciplinary approaches that address linguistic and cultural diversity in testing. He has conducted research on the development, translation, localization, and review of science and mathematics tests; the design of software for computer-assisted scoring; and the development of assessments for the professional certification of science teachers. He has been principal investigator in several National Science Foundation-funded projects that have examined the intersection of psychometrics and linguistics in testing. He is the author of the theory of test translation error, which addresses testing across cultures and languages. Also, he has investigated the use of generalizability theory—a psychometric theory of measurement error—in the testing of English language learners. He has advised Latin American countries on the development of national assessment systems. Also, he has been the advisor to countries in Latina America, Asia, Europe, and Northern Africa on test translation. Current research projects investigate the measurement of mathematics academic language load in tests, formative assessment practices for English language learners in the science classroom, and the design and use of illustrations as a form of testing accommodation for English language learners with an approach that uses cognitive science, semiotics, and sociolinguistics in combination.
