Persian language instructors at U.S. universities were surveyed regarding (1) their methods for measuring Persian language proficiency among American undergraduate students, (2) research verifying the validity and reliability of these methods, and (3) their definitions of Persian language proficiency. A 12-item questionnaire was completed by 17 Persian instructors. It was found that the respondents used diverse methods for assessing Persian language proficiency, that they have not conducted empirical research to verify these methods, and that they did not agree on a definition of Persian language proficiency. The respondents expressed willingness to conduct proficiency research and a need for additional learning materials. The questionnaire and a list of undergraduate Persian language programs in the United States are appended. (RW)
