In South Korea, the International Baccalaureate (IB) Middle Years Programme (MYP) has been implemented in public education for several years. This article explores the IB MYP's characteristics and educational effects by adopting the grounded theory research approach of Corbin and Strauss (1990, 2015). A total of 27 students from three public…

This study explores classification consistency and accuracy for mixed-format tests using real and simulated data. In particular, the current study compares six methods of estimating classification consistency and accuracy for seven mixed-format tests. The relative performance of the estimation methods is evaluated using simulated data. Study…

The main purposes of this study were to develop bi-factor multidimensional item response theory (BF-MIRT) observed-score equating procedures for mixed-format tests and to investigate relative appropriateness of the proposed procedures. Using data from a large-scale testing program, three types of pseudo data sets were formulated: matched samples,…

Preparing lifelong, world-ready German learners means German language instructors must intentionally incorporate globalized themes and tasks into the high school German curriculum. In 2010, the College Board redesigned the AP German Language and Culture Exam to meet these needs. The new exam encompasses six course themes and requires students to…

The psychometric considerations and challenges associated with including constructed response items on tests are discussed along with how these issues affect the form assembly specifications for mixed-format exams. Reliability and validity, security and fairness, pretesting, content and skills coverage, test length and timing, weights, statistical…

This catalog lists research reports, research notes, and other publications available from the College Board's website. The catalog briefly describes research publications available free of charge. Introduced in 1981, the Research Report series includes studies and reviews in areas such as college admission, special populations, subgroup…

Dorans and Holland (2000) and von Davier, Holland, and Thayer (2003) introduced measures of the degree to which an observed-score equating function is sensitive to the population on which it is computed. This article extends the findings of Dorans and Holland and of von Davier et al. to item response theory (IRT) true-score equating methods that…

Presented at the Annual National Council on Measurement in Education (NCME) in New York in March 2008. This presentation explores how different item weighting can affect the effective weights, validity coefficents and test reliability of composite scores among test takers.
