The second was to validate two final exams with several shared items. The exams were given to two groups of students with slightly differing English…

Despite calls for engaging assessments targeting young language learners (YLLs) between 8 and 13 years old, what makes assessment tasks engaging and how such task characteristics affect measurement quality have not been well studied empirically.

The "TOEFL"® family of assessments includes the "TOEFL"® Primary"™, "TOEFL Junior"®, and "TOEFL iBT"® tests. The linguistic complexity of stimulus passages in the reading sections of the TOEFL family of assessments is expected to differ across the test levels. This study evaluates the linguistic…

Previous research on differences in the reliability, validity, and difficulty of essay tests given under different timing conditions has indicated that giving examinees more time to complete an essay may raise their scores to a certain extent, but does not change the meaning of those scores, or the rank ordering of students. There is no evidence…

Methods of computerized adaptive testing using conventional scoring methods in order to develop a computerized placement test for the Test of English as a Foreign Language (TOEFL) were studied. As a consequence of simulation studies during the first phase of the study, the multilevel testing paradigm was adopted to produce three test levels…

This paper traces developments in educational psychology and measurement that led to the Test of English as a Foreign Language (TOEFL) and the test of English for International Communication (TOEIC) and the application of educational measurement terms such as validity and reliability to testing.
