A guide to the adaptation of oral proficiency testing for classroom language instruction contains excerpts of projects by participants in an American Council on the Teaching of Foreign Languages (ACTFL) workshop. The excerpts are examples of proficiency based curricula and materials designed to personalize instruction and simulate real-life situations for conversation and communicative practice. They include: proficiency guidelines for two levels of French instruction; vocabulary and questions developed for a unit on families and professions (French); drills focusing on students' personal experiences and activities (German); a list of first-year German functions and content based on ACTFL proficiency guidelines; an exercise in narration in past tense (Spanish); and role-play situations useful for a variety of languages.
