The aim of this study is to examine the knowledge levels of the teacher candidates registered in the pedagogical formation education certificate program in terms of "technological pedagogical field information (TPAB)" which professionally combine these three components according to various variables. The research was a descriptive study conducted using a survey model. The study's study group consisted of 272 students (n = 272) who continued to attend the pedagogical formation education certificate program of a university in the Eastern Anatolia Region and voluntarily participated in the research. The data were collected using the personal information form developed by the researchers and the Technological Pedagogical and Content Information (TPAB) Scale developed by ġahin (2011). As a result of the study, TPAB levels of participant students were found to be generally low and there is not a statistically significant difference between TPAB levels according to the gender and branches of the students, but there is a meaningful difference according to whether they have their own computers, whether they have easy access to the internete, their computer usage and high school graduation they graduated.
