There is enough evidence that, assessment of students’ performance is one of the challenges that face assessors in secondary schools. Despite the mitigations agreed to solve the challenges on evaluation of students’ performance in the country. Studies about evaluation of students’ performance that have been conducted in Tanzania have mainly focused on fixed grading method. To fill this gap, this quantitative study investigated students’ performance by comparing their performance using statistical quality control charts grade and fixed grading method. The study is guided by three specific objectives which were: to assess students’ performance of a subject by using individual control chart over fixed grading method, between subjects by using mean and S control chart over fixed grading method and within a school by using group control charts over fixed grading method. The study was conducted in ordinary secondary schools in Mbulu District. It employed secondary data which were collected from240 students’ sampled documents obtained from academic students’ progressive report from six ordinary secondary schools in Mbulu District. The students’ performance was analyzed as per specific objectives by using Minitab Statistical Software with the help of statistical quality control charts grade and fixed grading method. After the analysis of the collected data, the quality control charts grade revealed that more students were performing well as compared with the analysis done by fixed grading method. The findings implied that statistical quality control charts grade was a tool that caused a large number of students to pass their examinations as opposed to the fixed grading method in evaluation of students’ performance. This is because the statistical quality control charts grade lower the cut-off points of the students’ performance. These findings have an implication in evaluating students’ performance since secondary school teachers may use statistical quality control charts grade to increase individual students’ performance in each subject.enStudents performanceSecondary schoolMbuluStatistical quality control gradeFixed gradingStatistical ouality controlAcademic performanceSecondary educationDissertation
