In his working paper, Herczeg is seeking the answer for the question, how the size of a school influences the quality of the education. This question has relevancy, because according to international research results, the smaller school – especially in case of the disadvataged pupils – contributes more to the process of catching up.
In his research, he analised the quality of the education with the help of the mathematics and reading comprehension results of the National Competency Assessment, then he approximated the size of the school with two indicators: number of pupils in school and number of pupils per teacher. As his findings show, in itself, none of these factors have an impact on the performance of the students (provided that the pupils and schools are not different in their other significant features) and the results is valid among the disadvantaged pupils, too.
