Even though the adopted teaching-learning approaches and the curricula that are based on them are subject to change in an educational institution, teaching competencies and attitudes determine the basic quality of the educational system. The study mainly intends to determine the relationship between levels of teacher candidates' attitude to teaching and levels of their teaching-learning competencies. This study has a survey design as it identifies teacher candidates' attitudes toward the profession and teaching-learning process competencies, and a relational survey design as it explores whether attitudes toward the profession and teaching-learning competencies correlate or not. As the study aims to make a comparison between social sciences and science-math fields, the data was collected from 387 teacher candidates, whose subject fields can be grouped within these two areas. The data was collected through "Attitude to Teaching Profession Scale" and "Teaching Learning Process Competencies Scale". The results revealed that teacher candidates have a positive attitude towards the teaching profession and teaching competencies at high levels. In addition, it was found that teacher candidates' positive attitude correlates significantly with their teaching-learning competencies.
