Services Administration In Education. Utilizing Control Charts In Educational Management: An Approach For Assessing The Mathematics Scores In Panhellenic Examinations

Background: The choices offered to students and their parents complicate the process of finding an optimal solution that meets their needs, as competition increases1 . The management of each educational organization is responsible for providing services information and curricula offered by the tutorials, as well as for designing innovative, cost-effective, and efficacious solutions2 . A learning organization with a student-oriented marketing approach is considered by many researchers as an effective mix to mixture that meets the needs of customers, students, and parents3,4. An organization with the above-mentioned features which apprehends its position, predicts the behavior of its customers, meets their needs and preferences, and enables marketing to be much more targeted and successful. As a result, it provides highvalue services, which are its comparative advantage in the market5 . The evaluation and intervention of education service providers and curriculum designers ensures the correction of errors and the adaptation to student and societal needs in all educational system processes. One of the most reliable statistical control tools of quality services and processes is the mean and standard deviation control charts6 . Both respond to the requirements of in educational processes as they are described by the normal distribution. Materials and Methods In this work, the statistical tools have been utilized to analyze the mathematics scores in the economic and scientific studies orientation of the Panhellenic exams from 2003 to 20227 . The objective of this analysis is to investigate the application of control charts as statistical methods and identify the factors responsible for any out-of-control processes. Conclusion: The study findings revealed that the modification of the curricula (all chapters of Algebra topics were removed, and only mathematical analysis topics remained) negatively affected the mean students' scores from 2015 to 2017, with a simultaneous reduction of variance. Distance education which was mandated due to the pandemic crisis did not negatively affect the mean values of the mathematics scores and increased the variance. A decrease in the number of the Panhellenic exams candidates is expected due to the demographic problem of Greece8,9. Moreover, extensive learning gaps for students who were in high school and elementary school during distance education are evident10. Finally, the service administration authorities in educational organizations and those who are responsible for the development of educational strategies should monitor student performance with the use of appropriate tools. This will help them to adapt their policies, educational tools, and curricula to the current conditions if it would be necessary
