Comparison of IRT and MIRT theory models in graduate competences estimation

Dyadkin Yuriy Alekseevich

The article is dedicated to Item Response Theory (IRT) that is supposed to be an approach to graduate competences estimation. Graduate competences are treated as latent parameters that bring information of what professional skill level a graduate is on. Data of academic achievements are suggested to base on to get this task solved. The author describes pros and cons of different models used within IRT which allows to make conclusions of rational application of MIRT (Multidimensional Item Response Theory) models in represented sphere. Particularly Multidimensional Within-Item Partial Credit Model is suggested to use to implement author approach.
