Simulated Oral Proficiency Interview (SOPI)
The Simulated Oral Proficiency Interview (SOPI) is a tape-mediated test of speaking proficiency for high school students and older. All SOPI items are based on the speaking proficiency guidelines of the American Council on the Teaching of Foreign Languages (ACTFL). The test is presented to examinees via a test booklet and a master tape and can be administered individually by anyone using two tape recorders. It can also be used in a language laboratory setting to test groups. Learn more about the SOPI.

SOPI Rater Training Kits & Live Rater Training
The Self-Instructional Rater Training Kits teach professionals to use the ACTFL Proficiency Guidelines-Speaking to rate oral proficiency using the Simulated Oral Proficiency Interview. The kits consist of four parts in addition to the SOPI itself: Rater Training Kit Manual; Rater Training Kit Tapes; Rater Training Kit Workbook; and Rater Training Kit Reference Guide. For more information about ordering the SOPI Rater Training Kits, visit the CAL Store. For more information about live rater training workshops, contact CAL at

Language Proficiency Tests
CAL's language proficiency tests are designed to measure the general proficiency levels in listening and reading attained by English-speaking learners of a foreign language. All test materials are mailed to the institution; responses are marked on machine-scoreable answer sheets and returned to CAL for scoring. The tests consist of approximately 100-150 four-option multiple-choice questions (exact number varies by test).
