This study identified the four critical qualifications necessary for the understanding of the integral subject for math and science teachers candidates and the chances of candidates to have these qualifications were studied using the log-lineer cognitive diagnostic model from cognitive diagnostics models. In this context, the "Integral Achievement Qualification Test" was prepared, which measured these four critical qualifications and consisted of 25 already selectively asked questions, and was applied to a total of 190 Mathematics and Science Knowledge teachers candidates in the 2018-2019 educational year. This test, which has a high substance-capacity differentiability index, has been determined that each capacity is measured with .99, .98, .99, and .95, respectively. Specialist opinions on the sufficiency measureed by the test substances were taken and determined by Lawshe technique which sufficiency or sufficiency of each substance was measured. For the distribution of these four critical qualifications, the Q-matris was created and the possibilities of each candidate to have the relevant qualifications individually were calculated using the log-lineer cognitive diagnostic model using the MPlus 6.12 program. The results of the analysis found that the candidates for mathematics teachers were very likely to explain the concept of integral (99%) and know the methods of integral acceptance (88%); the level of conceptual knowledge was higher than the level of processional knowledge. The knowledge of the teachers is likely to have an uncertain comprehensive account. 76), it was found that it was very likely to be able to make applications using certain integrals (87%); it was found that the processing knowledge levels were higher than the conceptual knowledge levels.
