Abstract
Guidelines for the Assessment of English Language Learners was designed for test developers, testing program administrators, psychometricians and educational agencies. These guidelines were developed to ensure that assessments are fair and valid for English language learners. They focus on large-scale content area assessments administered in the United States to students in grades K–12. Many of these principles can also be applied to other populations and assessments.
