The purpose of this study is to develop the Tendency to Tolerance Scale and to analyze the tendencies of primary school students to tolerance through certain variables. The population of the study was comprised of 899 students who studied at five different primary schools located in Sakarya. The exploratory factor analysis yielded an 18-item measurement tool with 3 sub-factors, which accounted for 47.97% of the total variance. The sub-dimensions were "value", "acceptance" and "empathy". It was discovered that the internal consistency coefficient for the whole scale, the first factor, the second factor and the third factor are 0.89, 0.86, 0.70 and 0.63 respectively. The test-retest coefficient for the whole scale, the first factor, the second factor and the third factor are 0.84, 0.83, 0.73 and 0.82 respectively. The study found that the item-total correlation varied between 0.43 and 0.63 and all the differences between the 27% upper group and 27% tower group were significant. Furthermore, it was discovered that primary school students have a high tendency to tolerance, that female students are relatively more tolerant, that the tendency to tolerance is lowered as students proceed to higher grades, that the tendency to tolerance gets higher as mothers have a higher educational status, and that educational status of fathers has no influence on the tendency to tolerance.
