Item Selection and Ability Estimation in Adaptive Testing

Abstract

The last century saw a tremendous progression in the refinement and use of standardized linear tests. The first administered College Board exam occurred in 1901 and the first Scholastic Assessment Test (SAT) was given in 1926. Since then, progressively more sophisticated standardized linear tests have been developed for a multitude of assessment purposes, such as college placement, professional licensure, higher-education admissions, and tracking educational standing or progress. Standardized linear tests are now administered around the world. For example, the Test of English as a Foreign Language (TOEFL) has been delivered in approximately 88 countries.
