The purpose of this research paper is to obtain access to the teacher effectiveness of secondary school teachers in relation to their gender, location and type of school. For the conduct of the research, the survey approach was used. The Teacher Effectiveness Scale (2010) was created by Dr. Shallu Puri and Prof. S.C. Ghakhar to gather data from teachers in secondary schools. Samples of 130 secondary school teachers from the Jalandhar district of Punjab were randomly chosen for this research. To analyze the results, statistical techniques such as Mean, SD, and t-test were used. The result showed that at both stages of importance, there is no significant difference between female and male high school teachers. There is a significant difference between the effectiveness of urban and rural secondary school teachers at both levels, and there is a significant difference between the effectiveness of teachers among secondary school teachers with regard to the form of institution.
