The TOEFL test measures test takers’ ability to communicate in English‐medium colleges and universities.  \nThe TOEFL iBT™ test measures a candidate’s ability to combine listening, reading, speaking and writing skills with authentic and innovative integrated tasks, making it the most comprehensive English‐language proficiency test. Accepted by over 7,500 score users in more than 130 countries, the TOEFL test is the most widely recognized English‐language test in the world.  \nRecently, ETS conducted score comparison research between the TOEFL test and an alternative test, IELTS (International English Language Testing System) . For the research, ETS obtained a sample of 1,153 students who had both IELTS and TOEFL scores. Using equipercentile linking, the corresponding TOEFL score that would pass the same percentage of test takers for each IELTS scores was obtained. The score comparison results for each section (Listening, Speaking, Reading, and Writing) and the total test showed that most of the students scored in the middle to mid‐high score ranges on both tests. Limitations of the research and suggestions for future research are also discussed.  \nLinking TOEFL iBT ™ Scores to IELTS® Scores – A Research Report  \nLinking TOEFL iBT™ Scores to IELTS Scores  \nIntroduction  \nTOEFL® test scores have been widely accepted by educational and other institutions throughout the world as evidence of nonnative English speakers’ proficiency in English language use, and the TOEFL test has received very positive feedback from score users and instructors in the English as a Second Language (ESL) community.  \nThere are many occasions when scores from different tests or even from different versions of the same test need to be linked for decision making or other purposes. For example, the scores on the SAT® I and ACT® tests, two well known college admissions tests in the United States, have been linked to each other to help university admissions offices use the scores to evaluate applicants. A research study was carried out by both ETS and ACT research staff to develop a score comparison table for this purpose (Pommerich, Hanson, Harris,& Sconing, 2000. ) Another example is that, when the TOEFL iBT test, was developed to be taken via the Internet and to replace the computer‐adaptive test (cBT) version, a study was conducted to link TOEFL iBT scores to TOEFL cBT scores (Wang, Eignor, & Enright, 2007. )  \nRecently, ETS conducted score comparison research between the TOEFL test and an alternative test, IELTS (International English Language Testing System) . As a best practice required by the Guidelines for Practice by the International Language Testing Association (ILTA, 2007), the Standards for Educational and Psychological Testing (AERA, APA, NCME, 1999), and the ETS standards (ETS, 2002, p. 45,), appropriate psychometric procedures should always be used to link scores from two different assessments if the scores are to be compared. To comply with this standard, ETS psychometric staff conducted a research study to explore and establish empirical relationships between the scores on the two tests. This research was designed and carried out to answer the following two research questions:  \n1. What TOEFL iBT section scores are comparable to IELTS section scores?  \n2. What TOEFL iBT total scores are comparable to IELTS total scores?  \nLinking TOEFL iBT ™ Scores to IELTS® Scores – A Research Report  \nFinding the corresponding TOEFL iBT scores for each of the IELTS scores was accomplished by what is known as score linking or score comparison (called score comparison hereafter in this report) in the field of educational measurement.  \nIn this report, the samples and the","cbCaita1qOoXWmFz","https://ap.wps.com/l/cbCaita1qOoXWmFz","pdf",1125337,17,"English","# Abstract\n# Introduction\n# Method\n## Data Collection","[{\"question\":\"Why does ETS link TOEFL iBT scores to IELTS scores?\",\"answer\":\"ETS links the scores so institutions can compare and make decisions using results from two different English proficiency tests under required psychometric standards.\"},{\"question\":\"What data did the research use for the score comparison?\",\"answer\":\"ETS collected TOEFL and IELTS scores from 1,153 students who took both tests, after cleaning records with missing or invalid section scores.\"},{\"question\":\"How were TOEFL iBT scores matched to IELTS scores?\",\"answer\":\"ETS used equipercentile linking to obtain the corresponding TOEFL iBT score that would pass the same percentage of test takers for each IELTS score, reporting results by section and total score.\"}]","Linking TOEFL iBT Scores to IELTS Scores - A Research Report | PDF",1790810901,43]
