The aim of this study was to evaluate students' perceptions of the quality of mathematics education and to develop a reliable and valid measurement tool. The research was conducted with 638 (first study) and 407 (second study) secondary school students in Eskisehir, Turkey. Item discrimination, structural validity (exploratory factor analysis and confirmatory factor analysis) and internal consistency were examined. The findings showed that the Mathematics Education Quality Scale (MEQS) was formed by five factors, namely: (i) quality of instruction; (ii) quality of school environment; (iii) quality of teacher; (iv) quality of family cooperation; and (v) quality of school guidance, and it was valid and reliable. As a result, it could be argued that the MEQS can be used to measure secondary school students' perceptions of the quality of mathematics education.
