All TOEIC® Research

The TOEIC® program is used by organizations around the world to prepare graduates for the global work environment and to hire, place, train and promote employees.

In order to provide valid, fair and reliable test scores to these organizations, the TOEIC® Research Program aims to support the quality of the TOEIC® tests through ongoing research.

In addition, ETS and the TOEIC Program are committed to advancing English-language teaching and learning by providing:

  • consistent and reliable test scores
  • score interpretations that are meaningful, fair and relevant to the real world
  • scores that can be used to make fair and equitable decisions reflecting the needs and priorities of score users
  • beneficial outcomes to test takers and score users with a positive impact on the teaching and learning of English worldwide

For an inclusive overview, see a list of all TOEIC research studies and reports in one place and understand why organizations trust TOEIC scores for their relevant decision making.

  • Monitoring Score Change Patterns to Support TOEIC® Listening and Reading Test Quality

    In large-scale, high-stakes testing programs, such as the TOEIC program, some test takers take a test more than once over time. The score change patterns of these so-called "repeaters" can be analyzed to support the overall quality of the test (e.g., its reliability, validity, intended uses). This study examined the aforementioned score change patterns, with the goal of evaluating the reliability and validity of TOEIC® Listening and Reading test scores.

  • Assessing English-Language Proficiency In All Four Language Domains: Is It Really Necessary?

    This article examines and argues in favor of assessing English-language proficiency using a comprehensive four-skill assessment (i.e., listening, speaking, reading and writing) rather than just a select subset of those skills. Different use cases for TOEIC tests lead to the conclusion that in most cases, English-language proficiency is best evaluated using a comprehensive four-skill assessment.

  • Mapping TOEIC® Test Scores to the STANAG 6001 Language Proficiency Levels

    STANAG 6001 is a NATO Standardization Agreement which describes explicit listening, speaking, reading and writing proficiency levels necessary for military personnel. This study aimed to identify which minimum scores for each of the TOEIC tests' four skill areas correspond to the different STANAG proficiency levels. Thus, this study provides guidance to score users who need to make decisions about language proficiency based on achievement of STANAG proficiency levels.

  • Monitoring TOEIC® Listening and Reading Test Performance Across Administrations Using Examinees' Background Information

    The scoring process for the TOEIC Listening and Reading test includes monitoring procedures that help ensure that scores are consistent across different forms and test administrations, and that skill interpretations are fair. This study explores the possibility of using information about test takers' backgrounds in order to enhance several types of monitoring procedures. Results of the analyses suggested that some background variables may facilitate the monitoring of test performance across administrations, thereby strengthening quality control procedures for the TOEIC Listening and Reading test as well as strengthening evidence of score consistency.

  • Linking TOEIC® Speaking Scores Using TOEIC® Listening Scores

    In testing programs, multiple forms of a test are used across different administrations to prevent overexposure of test forms and to reduce the possibility of test takers gaining advance knowledge of test content. Because slight differences may occur in the statistical difficulty of the alternate forms, a statistical procedure known as test score linking has been commonly used to adjust for these differences in difficulty so that test forms are comparable.

  • The Incremental Contribution of TOEIC® Listening, Reading, Speaking and Writing Tests to Predicting Performance on Real-Life English-Language Tasks

    This study investigated whether proficiency in a particular language skill (e.g., speaking) could be better estimated by considering not only the TOEIC test scores corresponding to that skill, but also TOEIC tests scores for other skills. The results supported this assertion, suggesting that scores on the four-skill TOEIC tests together provide a more valid measurement of English-language proficiency than any skill in isolation.

  • Alternate Forms Test-Retest Reliability and Test Score Changes for the TOEIC® Speaking and Writing Tests

    The reliability or consistency of scores can be examined in a variety of ways, including the degree to which scores for the same test taker are consistent across different test forms (so-called "equivalent forms reliability") and different occasions of testing ("test-retest reliability"). This study examined the consistency of TOEIC Speaking and Writing scores across different test forms at different time intervals (e.g., 1–30 days, 31–60 days) and found that test scores had reasonably high equivalent form test-retest reliability.

  • Evidence-Centered Design: The TOEIC® Speaking and Writing Tests

    Evidence-Centered Design (ECD) is an assessment development methodology which explicitly clarifies what an assessment measures and supports skills interpretations based on test scores. This paper describes the ECD processes used to develop the TOEIC Speaking and Writing tests. Evidence collected through the test design process produced foundational support for the validity of TOEIC Speaking and Writing test score interpretations.

  • Constructed-Response (CR) Differential Item Functioning (DIF) Evaluations for TOEIC® Speaking and Writing Tests

    Differential item functioning (DIF) is a statistical procedure used to identify items or tasks that are unexpectedly biased in some way, inappropriately favoring one group of test takers over another. One of the challenges for speaking and writing tests is the lack of proven, practical DIF techniques that can be used to analyze performance-based or "constructed-response" tests. This paper investigates several such techniques and illustrates how research is being conducted to ensure the fairness of score interpretations.
