Mentoring and coaching are effective ways to affect the workers' growth positively with a purpose to assist them to deal productively with the overwhelming duties and the uncertain environment. This paper aims to share findings from a master's study investigating the impact of a combined mentoring and coaching technique on teacher pedagogic growth. Combining these two techniques is a vigorous technique to approach teachers and encourage them to grow their potential competencies. The method used was action research with a small-scale investigation examining the principal's interaction with two teachers from SMP Immanuel Pontianak. The data needed in this study were collected using an observation rubric and Glickman's quadrant to record the teaching performance, based on two categories (Abstraction and Commitment), and measure teacher pedagogic competence growth. Success indicators from this research were the shifting position in the Glickman's quadrant and/or the increasing scores of each category. The results showed that one of the teachers moved to the higher quadrant and significantly increased the overall score, while the other teacher only experienced a score increment without shifting quadrant. The primary implications to underline were the importance of applying the chosen approaches consistently and considering the teachers' motivation as another determinant success key factor.
