Multistage testing (MST), a variant of computerized adaptive testing (CAT), differs from conventional CAT in that it is adapted at the module level rather than at the individual item level. Typically, all examinees begin the MST with a linear test form in the first stage, commonly known as the routing stage. In 2020, Han introduced an innovative…

To solve the attenuation paradox in computerized adaptive testing (CAT), this study proposes an item selection method, the integer programming approach based on real-time test data (IPRD), to improve test efficiency. The IPRD method turns information regarding the ability distribution of the population from real-time test data into feasible test…

Multistage adaptive testing (MST) has become popular in the testing industry because the research has shown that it combines the advantages of both linear tests and item-level computer adaptive testing (CAT). The previous research efforts primarily focused on MST design issues such as panel design, module length, test length, distribution of test…

Many international large-scale assessments (ILSAs) have switched to multistage adaptive testing (MST) designs to improve measurement efficiency in measuring the skills of the heterogeneous populations around the world. In this context, previous literature has reported the acceptable level of model parameter recovery under the MST designs when the…

Inclusive large-scale assessments have become the norm in states across the U.S. Participation rates of students with disabilities in these assessments have increased dramatically since the mid-1990s. As consortia of states move toward the development and implementation of assessment systems that include both non-summative assessments and…

This report summarizes the design and development of an adaptive e-learning prototype for middle school mathematics for use with both sighted and visually disabled students. Adaptation refers to the system's ability to adjust itself to suit particular characteristics of the learner. The main parts of the report describe the system's theoretical…
