Effect of Total Quality Management Through Continuous Improvement Practices on Students’ Academic Achievement

Abstract

Quality education remains central to national development, prompting educational institutions to adopt corporate management frameworks. TQM emphasizes continuous improvement, customer satisfaction, and stakeholder involvement. Applied to education, it positions students as the primary “customers” and academic success as the “product.” Despite substantial investment in education, many developing countries still experience poor academic performance and weak quality assurance systems. This study examined the influence of continuous improvement practices, specifically continuous assessment, feedback mechanisms, and student involvement on students’ academic achievement in private secondary schools in Delta State, Nigeria. A descriptive survey research design with a quantitative approach was employed. From a population of 2000 final-year secondary school students, 322 were selected using stratified random sampling. Data were collected with a validated questionnaire (Cronbach Alpha = 0.87) and analyzed using SPSS 25 through descriptive statistics and multiple regression. Findings revealed that continuous assessment (β = 0.380, p < 0.001), feedback mechanisms (β = 0.320, p < 0.001), and student involvement (β = 0.260, p = 0.001) have significant positive effects on students’ academic achievement. Collectively, these practices explained 50.3% of the variance in achievement (Adjusted R² = 0.503), while ANOVA confirmed the model’s fitness (F (3, 296) = 58.230, p < 0.0005). The study concludes that embedding continuous improvement practices within the TQM framework enhances student outcomes. It recommends institutionalizing continuous assessment, providing timely feedback, and actively involving students in academic decision-making to foster sustained achievement.
