Since its initial launch in 1964, the TOEFL® test has undergone several major revisions motivated by advances in theories of language ability and changes in English teaching practices. The most recent revision, the TOEFL iBT test, was launched in 2005. It contains a number of innovative design features, including integrated tasks that engage multiple skills to simulate language use in academic settings and test materials that reflect the reading, listening, speaking, and writing demands of real-world academic environments.  \nIn addition to the TOEFL iBT test, the TOEFL® Family of Assessments was expanded to provide high-quality, English proficiency assessments for a variety of academic uses and contexts. The TOEFL® Young Students Series features the TOEFL Primary® and TOEFL Junior® tests, which are designed to help teachers and learners of English in school settings. In addition, the TOEFL ITP® program offers colleges, universities, and others affordable tests for placement and progress monitoring within English programs as a pathway to eventual degree programs.  \nAt ETS, we understand that scores from the TOEFL Family of Assessments are used to help make important decisions about students, and we would like to keep score users and test takers up-to-date about the research results that help assure the quality of these scores. Through the publication of the TOEFL ® Research Insight Series, we wish to communicate to the institutions and English teachers who use the TOEFL tests the strong research and development base that underlies the TOEFL Family of Assessments and demonstrate our continued commitment to research.  \nSince the 1970’s, the TOEFL test has had a rigorous, productive, and far-ranging research program. But why should test score users care about the research base for a test? In short, it is only through a rigorous program of research that a testing company can substantiate claims about what test takers know or can do based on their test scores, as well as provide support for the intended uses of assessments and minimize potential negative consequences of score use. Beyond demonstrating this critical evidence of test quality, research is also important for enabling innovations in test design and addressing the needs oftest takers and test score users. This is why ETS has established a strong research base as a fundamental feature underlying the evolution of the TOEFL Family of Assessments.  \nThis portfolio is designed, produced, and supported by a world-class team of test developers, educational measurement specialists, statisticians, and researchers in applied linguistics and language testing. Our test developers have advanced degrees in fields such as English, language education, and applied linguistics. They also possess extensive international experience, having taught English on continents around the globe. Our research, measurement, and statistics teams include some of the world’s most distinguished scientists and internationally recognized leaders in diverse areas such as test validity, language learning and assessment, and educational measurement.  \n2 TOEFL ® Research Insight Series, Volume 3: Reliability and Comparability of TOEFL iBT® Scores  \nTo date, more than 300 peer-reviewed TOEFL Family of Assessments research reports, technical reports, and monographs have been published by ETS, and many more studies on TOEFL tests have appeared in academic journals and book volumes. In addition, over 20 TOEFL test-related research projects are conducted by ETS’s R","cbCaidmLGTJBh9JM","https://ap.wps.com/l/cbCaidmLGTJBh9JM","pdf",5338243,16,"English","# Preface\n# Purpose of the TOEFL Research Insight Series\n## Research base and score quality assurance\n## Teams, contributors, and collaboration","[{\"question\":\"What is the TOEFL Research Insight Series Volume 3 focused on?\",\"answer\":\"It focuses on the reliability and comparability of TOEFL iBT scores and the research base that supports score quality.\"},{\"question\":\"Why does the document emphasize the importance of research for test scores?\",\"answer\":\"It argues that rigorous research substantiates what test takers know or can do, supports intended score uses, and helps minimize negative consequences.\"},{\"question\":\"What design and test features are highlighted for the TOEFL iBT?\",\"answer\":\"The document describes integrated tasks that engage multiple skills and test materials aligned with the reading, listening, speaking, and writing demands of academic settings.\"}]","TOEFL Research Insight Series - Volume 3 - Reliability and Comparability of TOEFL iBT Scores | PDF",1790811510]
