In this research report, we describe a study to map the scores of the "TOEFL® Essentials"™ test to the Canadian Language Benchmarks (CLB). The TOEFL Essentials test is a four-skills assessment of foundational English language skills and communication abilities in academic and general (daily life) contexts. At the time of writing this…

The past decade has seen an emerging interest in mapping (aligning or linking) test scores to language proficiency levels of external performance scales or frameworks, such as the Common European Framework of Reference (CEFR), as well as locally developed frameworks, such as China's Standards of English Language Ability (CSE). Such alignment is…

Federal accountability requirements after the No Child Left Behind (NCLB) Act of 2001 and the need to report progress for various disaggregated subgroups of students meant that the methods used to set and articulate performance standards across the grades must be revisited. Several solutions that involve either "a priori" deliberations…

Logistic regression (LR)-based methods have become increasingly popular for predicting and articulating cut scores. However, the precision of predictive relationships is largely dependent on the underlying correlations between the predictor and the criterion. In two simulation studies, we evaluated the impact of varying the underlying grade-level…

For standard- or criterion-based assessments, the use of cut scores to indicate mastery, nonmastery, or different levels of skill mastery is very common. As part of performance summary, it is of interest to examine the percentage of examinees at or above the cut scores (PAC) and how PAC evolves across administrations. This paper shows that…

The purpose of this study was to collect recommendations for minimum score requirements (cut scores) on the "TOEFL Junior"® English language proficiency test in order to guide decisions on the placement of learners into English as a second language (ESL) support classes. The TOEFL Junior test, intended primarily for students ages 11 and…

In line with expanded conceptualizations of validity that encompass the interpretations and uses of test scores in particular policy contexts, this report presents results of a comparative analysis of institutional understandings and uses of 3 international English proficiency tests widely used for tertiary selection--the "TOEFL iBT"®…

We examined the appropriateness of the anchor composition in a mixed-format test, which includes both multiple-choice (MC) and constructed-response (CR) items, using subpopulation invariance indices. We derived linking functions in the nonequivalent groups with anchor test (NEAT) design using two types of anchor sets: (a) MC only and (b) a mix of…

The purpose of this study is to determine the extent of scale drift on a test that employs cut scores. It is essential to examine scale drift in a testing program using new forms that are often put on scale through a series of intermediate equatings (known as equating chains). This may cause equating error to accumulate to a point where scale…

Equating under the external anchor design is frequently conducted using scaled scores on the anchor test. However, scaled scores often lead to the unique problem of creating zero frequencies in the score distribution because there may not always be a one-to-one correspondence between raw and scaled scores. For example, raw scores of 17 and 18 may…

Some probabilistic illustrations of the reliability coefficient are provided to assist in interpretation of this measure. All explanations are derived under the assumption that the joint distribution of examinee scores from two parallel tests is well approximated by a bivariate normal distribution.

The Common European Framework of Reference (CEFR) describes language proficiency in reading, writing, speaking, and listening on a 6-level scale. In this study, English-language experts from across Europe linked CEFR levels to scores on three tests: the TOEFL® iBT test, the TOEIC® assessment, and the TOEIC "Bridge"™ test.…

Although the primary use of the speaking section of the Test of English as a Foreign Language™ Internet-based test (TOEFL® iBT Speaking test) is to inform admissions decisions at English medium universities, it may also be useful as an initial screening measure for international teaching assistants (ITAs). This study provides criterion-related…
