The present investigation was undertaken to study the perceptions and expectations of secondary school students regarding the quality of services in schools on the basis of board affiliation. The researcher had selected 1281 secondary school students from schools of Greater Mumbai as sample for this study. Service quality rating scale by Parasuraman and Zeithaml(1985) was used as tool for the study. In order to describe the data collected, numerical determinants like mean, median, mode, standard deviation, skewness and kurtosis were worked out. ANOVA and t-test was done to find out the significance difference between the groups. The study found that there is no significant difference in the perceptions of secondary school students on service quality dimensions i.e. reliability, responsiveness, and assurance, whereas a significant difference was found in the perceptions on tangibles and empathy dimensions of service quality on the basis of board affiliation. However there is a significant difference in the expectations of secondary school students on service quality dimensions i.e. tangibles, reliability, responsiveness, assurance and empathy on the basis of board affiliation.
