Implementation of the Six Sigma Methodology to Improve Learning Outcomes in Public Schools in the Kingdom of Saudi Arabia Using the National Qualifications Standard

Abstract

The study aimed to assess the extent to which the Six Sigma methodology is applied to improve learning outcomes in public schools in the Kingdom of Saudi Arabia, based on the National Qualifications Framework, from the perspective of school principals. Using a descriptive-analytical approach, the researcher developed a questionnaire and conducted interviews to collect data. The study sample included 248 male and female principals randomly selected from public schools in Jeddah during the academic year 1446 AH. Findings revealed that the overall application of the Six Sigma methodology in improving learning outcomes was high, with an average score of 3.58 (SD = 0.68). Among the dimensions studied, strategic development ranked highest with a mean score of 3.71 (SD = 0.67), followed by problem-solving at 3.64 (SD = 0.89), both reflecting a high level of implementation. The dimension of radical transformation scored the lowest with a mean of 3.10 (SD = 0.60), indicating a moderate level of application. Additionally, statistically significant differences were observed based on academic qualifications, years of administrative experience, and the number of training courses attended. Principals holding a master’s degree, those with less than five or more than ten years of experience, and those who had completed more training courses demonstrated higher application levels of the Six Sigma methodology. Based on these findings, it is recommended to strengthen professional development by providing targeted Six Sigma training programs for school principals, especially focusing on enhancing radical transformation practices. Further emphasis should be placed on encouraging advanced academic qualifications among school leaders and supporting continuous learning to sustain high-quality implementation. Additionally, fostering strategic leadership and problem-solving skills will further enhance the methodology’s effectiveness in improving learning outcomes across public schools.
