The aim of this study is to investigate the standard validity of the PISA 2003 and 2012 mathematical literature scores with the help of expectation tables and conformity analysis. For this purpose, the PISA 2003 and 2012 problem-solving skills scores have been used. The points are categorized in 3 different ways. In the first place, the scores used by the PISA were used. The PISA score is 357 and the gold is 7 categories. Furthermore, the scores are divided into 10% and 20% scores, with expectation tables created, visually interpreted with drop-down graphics, and an analysis of conformity was made to study the conformity between categories. The study found that when mathematical scores were categorized into 20% scores, more compatible results were obtained than 10% scores, and the rates in the forecast tables increased. It can be said that the problem-solving score categories are similar to the mathematical score categories in the PISA score category.
