Equating test forms relies on anchor items to establish cross-form comparability, ensuring that scores from different versions of the same test can be interpreted on a common scale. Test form equating allows fair comparisons of examinees who take different test versions, compensating for minor variations in difficulty across forms. Anchor items function as a bridge between forms, … Baca Selengkapnya

Computer adaptive testing (CAT) is an assessment method that selects questions based on a test-taker’s ability level, and item exposure control is a critical mechanism to prevent overuse of certain questions, thereby maintaining test security and validity. Item exposure control test security is vital for preserving the integrity of high-stakes exams by limiting how often specific items … Baca Selengkapnya

Question answer calibration using the Rasch model represents the gold standard for creating fair, accurate, and truly adaptive testing systems. By mathematically decoupling the difficulty of a question from the ability of the examinee, the Rasch model for adaptive testing ensures that assessments remain precise across a broad spectrum of skill levels. This model is … Baca Selengkapnya
