This study investigates the quality of higher education institutes’ (HEIs’) administrative services by assessing student satisfaction in the context of Total Quality Management (TQM). Differences between students’ perceptions and expectations of administrative service quality are examined and discussed. A questionnaire survey was developed employing the SERVQUAL service quality model, the results of which were further enhanced by the application of importance-performance analysis (IPA). All five dimensions of the model were explored (reliability, assurance, tangibles, empathy, and responsiveness) with data from the 104 students from five Greek HEIs who participated in the survey. The results of the IPA complemented the survey research by enabling recommendations for importance and performance. The study’s findings indicate that students’ expectations are not met by the administrative services provided at the time of examination. A gap is observed between perceptions and expectations on all dimensions, indicating the necessity to make improvements to enhance service quality.

The research's aim is to assess the services offered by Greek public secondary education schools, with the intention of identifying any discrepancies between students' expectations and their perceptions of the final services provided. The gaps discovered indicate that the school's educational services are not meeting student expectations in the five quality dimensions of the SERVQUAL model. To be specific, the average expectations are 4.44, perceptions are 3.11, and gaps are -1.33. The schools examined had a greater discrepancy in the dimensions measuring safety and emotional understanding, which was observed. The fact that the 5 factors are correlated with each other indicates the model's reliability. However, in relation to the independent variables of gender, age, and class, there appears to be a positive correlation across all factors, which is very weak and not statistically significant. In contrast, a low negative correlation appears to be present between only the demographics being considered. Therefore, demographic characteristics do not affect the quality of education in secondary schools. Our findings benefit decision-makers by assisting them in taking corrective actions necessary to enhance the quality of services provided by schools as part of a continuous improvement process in order to achieve a higher level of excellence.
