Abstract:
The estimation of the cognitive ability of an individual is an important part of the
educational process. The main goal of every test theory is to create tests that are objective
along the entire range of abilities of the tested audience. Or in other words – the final ability
estimate of every individual needs to reflect his/her knowledge, regardless of the amount of
knowledge he/she possesses. Two theories are widespread nowadays – the Classical Test
Theory (CTT) and the Item Response Theory (IRT). This paper reviews some of the
disadvantages of CTT for creation of objective and balanced tests and demonstrates how
these disadvantages can be overcome when the more modern IRT is applied.
