This set of materials consists of three research reports concerning cultural and linguistic acculturation of minority children, and information about Acculturation Quick Screen, a technique, which includes computer software, for measuring students' relative level of acculturation to the public school environment in the United States. The research reports include a study examining the presence of and interaction between educational and cultural/linguistic characteristics of children experiencing acculturation, and a two-part report of a study of five Colorado school districts that examined the assessment and instruction of culturally and linguistically diverse children, learners of English as a Second Language. The Acculturation Quick Screen method and software (Acculturation Quick Screen Wizard) based on this and other research are then described, and techniques for their use are discussed.
