Three questionnaires are offered as language planning aids. These instruments measure variables in language background, language behavior, and language policy, particularly in situations where two or more dialects of languages are used. The first questionnaire asks 60 questions designed to form a language background profile of an individual. The second elicits an individual's history of language behavior on a time scale. The third questionnaire is a guide to obtaining a sociolinguistic community profile for language policy and educational programs. (JB)
