Achieving educational goals is based on the skills and competence of teachers; therefore, professional development of teachers is important to policy and decision-makers. Worldwide, the percentage of teachers who leave the profession within their first years of teaching is high therefore, professional support is essential to ease on their integration. Previous research indicates a positive and significant correlation between teachers' self-efficacy and their attitudes toward the teaching profession. Our study included three hypotheses: 1) teachers' pedagogical applications serve as mediators for the relationship between teachers' self-efficacy and their attitudes toward the profession; 2) participating in a professional development school (PDS) training program interacts with teachers' self-efficacy in predicting their attitudes toward the profession; and, 3) participation in a PDS training program will positively affect the two variables. A close and open-ended questionnaire was replied by 300 novice teachers, some of whom participated in the PDS program and others who did not. Findings indicate that the relationship between teachers' sense of self-efficacy and their attitudes towards the teaching profession was partially mediated by: applying constructivist pedagogical practices; matching to differences between learners; collaboration between fellow teachers; accountability; planning and teaching management; and academy-community relationships. Participation in a PDS program was not found as a moderator variable for this relationship, but novice teachers who participated in this program had a significant higher sense of self-efficacy and more positive attitudes towards the teaching profession. Findings are important for designing novice teacher training programs with an emphasis on the implementation of specific pedagogical practices.
