The instrument for Colorado's Foreign Language Proficiency Sample Project and directions for its administration are provided in this document. The project is a voluntary, teacher-designed and -administered effort to standardize high school student language proficiency assessment techniques. The materials are used in teacher workshops. The instrument is used to gather student language samples and rate student skills in speaking, listening, reading, and writing. The first section states the rationale for the project, summarizes the American Council on the Teaching of Foreign Languages' (ACTFL) proficiency guidelines for the novice and intermediate levels, outlines the hierarchy of language learning, and compares the number of hours in a typical secondary language class to that of the Foreign Service Institute. The second section contains questions with an explanation of how to conduct an oral interview with a beginning level student. A flow chart for evaluating oral samples is included. Section 3 contains the beginner writing assessment; section 4 contains beginner and mid-level reading and listening assessments; section 5 consists of the mid-level speaking assessment; and the 6th section is the mid-level writing assessment. Section 8 is an appendix containing a memo to users describing the project, rating scales, follow-up memos, and a brief bibliography. (MSE)
