The process of developing, piloting, and refining an oral proficiency test as part of the Center for Language Education and Research (CLEAR) test battery is described. The test was designed to fill a need for an oral interview-type measure adapted for fifth to seventh grade students. The test was produced first for Spanish immersion students, then adapted for English-as-a-Second-Language (ESL) students at the same grade level, resulting in the CLEAR Oral Language Proficiency Exam (COPE) in Spanish and English. The report has five sections. The first discusses the background of the project briefly. The second outlines precedents and procedures. Sections three and four describe the COPE-Spanish trial administrations and ESL adaptation and trials, respectively. The final section offers conclusions and recommendations for this segment of test development. Clinical testing and validity and dimensionality recommended studies for the exam are reported in a 1988 addendum report. (MSE)
