Test information and it using by Beatričė Andziulienė, Arūnas Andziulis, Sonata Bakanauskaitė

“… The questions of quality of test and test information by using Items Response Theory (IRT) are discussed in this work. Using the IRT gives many chances to make an effective test: to measure not only difficult of everyone test's item, but what number of information it brings in test; to get an even distribution of items by its difficulty which is harmonize with abilities of testing person; if it's known how many item gets information in test, it's possible to make a test which will evaluate the abilities of testing person group best. …”
