Quizplus · Accepted Answer

IRT (Item Response Theory) and CTT (Classical Test Theory) are both routinely used in the development of contemporary tests. IRT is often preferred for its ability to handle different test lengths and its adaptability in computerized adaptive testing. CTT, being simpler and more traditional, is still widely used, especially in educational settings and for tests where IRT's advantages are not as critical.
