The main purpose of the study on which this paper is based was to assess the effectiveness of the Teachers’ Service Commission in ensuring quality services to public secondary school teachers in Ruangwa District. Using a mixed research technique, the study collected both qualitative and quantitative data. The targeted population of the study was 126; the sample size of 88 drawn from the targeted population. The data collection tools involved the questionnaire, in-depth interview, and documentary review. Qualitative data were analysed thematically, while quantitative data were analysed through descriptive statistics with the help of the Statistical Package for Social Science (SPSS) version 21. The study was guided by Transformation Leadership Theory founded by James MacGregor Burns in 1978. The findings revealed that the Teachers’ Service Commission had been ineffective as it failed to promote teachers timely and to administer in-service training programmes for secondary school teachers who qualified. This is because the employer (the government) has the upper hand in deciding whether to pay for promotions and in-service training programmes or not. The study recommends that TSC should be empowered by making it have a say or being in control of the salary system
