Many different arguments have been offered in order to explain how social economic, student attitude and school size might affect mathematics achievement. This study focuses on explaining the importance of school size and student teacher ratio in affecting students' mathematics scores in Indonesia using data from PISA 2018. Total observations used in this study were 9,090 students from 308 schools. The multilevel analysis results showed that the higher the school size the higher the student's mathematics achievement, while in contrast with the student teacher ratio. In addition, the index of economic, social and cultural status and attitude towards school were found to be significant variables affecting the students' mathematics achievement. © 2022 Author(s).
