The study investigated the criterion-related validity of the Test of English as a Foreign Language™ Internet-based test (TOEFL ® iBT) Listening section by examining its relationship to a criterion measure designed to reflect language-use tasks that university students encounter in everyday academic life: listening to academic lectures. The design of the criterion measure was informed by students' responses to a survey on the frequency and importance of various classroom tasks that require

The criterion measure consisted of three videotaped lectures (in physics, history, and psychology) and included tasks created by content experts who are former university professors of the relevant content area. These tasks reflected what the content experts expected students to have comprehended during the lecture. The criterion measure and the TOEFL iBT Listening section were administered to nonnative speakers of English who were enrolled in undergraduate and graduate programs. Data from 221 participants were analyzed. Substantial correlations were observed between the criterion measure and the TOEFL iBT Listening section score for the entire sample and for subgroups (Pearson correlation coefficients ranging from .56 to .74 and disattenuated correlations ranging from .62 to .82). Moreover, the analysis of the mean scores on the criterion measure for different ability groups indicated that participants who scored at or above typical cut scores for international student admission to academic programs (i.e., TOEFL iBT Listening section score of 14 or above) scored, on average, nearly 50% or more on the criterion measure, demonstrating reasonable comprehension of the academic lectures. Since its inception in 1963, the TOEFL has evolved from a paper-based test to a computer-based test and, in 2005, to an Internet-based test, TOEFL iBT. One constant throughout this evolution has been a continuing program of research related to the TOEFL test. From 1977 to 2005, nearly 100 research and technical reports on the early versions of TOEFL were published. In 1997, a monograph series that laid the groundwork for the development of TOEFL iBT was launched. With the release of TOEFL iBT, a TOEFL iBT report series has been introduced. Currently this research is carried out in consultation with the TOEFL Committee of Examiners. Its members include representatives of the TOEFL Board and distinguished English as a second language specialists from the academic community. The Committee advises the TOEFL program about research needs and, through the research subcommittee, solicits, reviews, and approves proposals for funding and reports for publication. Members of the Committee of Examiners serve four-year terms at the invitation of the Board; the chair of the committee serves on the Board. Current (2008-2009) members of the TOEFL Committee of Examiners are: To obtain more information about the TOEFL programs and services, use one of the following: E-mail: Web site: iii Acknowledgments This project could not have been completed without the help of many individuals.
