This research focussed on how organizational climate and pedagogical competency affect learning effectiveness of government teachers within primary school in the area of the Tanah Sereal sub-district. In this area, it seems that government teachers have yet to make use the two variables in improving their learning effectiveness. The research employed 107 sampled teachers using proportional random sampling and is analysed using correlation. Hypothetical testing using parametric statistical analysis in the form of simple and multiple linear regression analysis, simple and multiple correlation analysis, and partial analysis with significant levels α=0.01 and α=0.05. Three conclusions are as the result of the research. Firstly, there is a significant positive correlation between organizational climate and learning effectiveness with the correlation coefficient Ry1=0.841, and the determinant coefficient of Ry1 2 =0.7068. Secondly, there is a significant positive correlation between pedagogical competency with learning effectiveness with correlation coefficient of Ry2=0.77, and determinant coefficient of Ry2 2 =0.5997. Thirdly, there is a highly significant positive correlation between organizational climate and pedagogical competency along with learning effectiveness with correlation coefficient of Ry.12=0.886 and determinant coefficient of Ry 122 =0.785. The research is considered as one of the applied examples for the current policy the so-called "Merdeka Belajar" which gives freedom for empowering the school environment including the competency of teachers.
