The first part briefly outlines the theory on rater effect. Mainly the measurement aspect is presented, the psychological bases of the scoring process are not discussed. In the second part selected models of rater effect analysis are described. Amongst them, the hierarchical rater model with signal detection theory is considered as covering the broadest range of different types of rater effect. This model was used in simulations to check its usefulness for data analysis of upper secondary school leaving examination in Poland."]
