Fuzzy clustering has been widely utilised to handle various types of data. This method is particularly effective for grouping large datasets due to its ability to manage complex structures. This study aimed to classify and correctly utilise school accreditation data. The data was obtained from 230 schools that had scores below the national average standard in education in 2021. The results of the study indicated that the fuzzy clustering analysis achieved satisfactory accuracy, demonstrating its effectiveness in correctly data grouping. Furthermore, fuzzy clustering showed highly significant performance in categorising datasets. This study can be beneficial to accreditation institutions and policymakers for making informed decisions to improve the quality of education by effectively utilising datasets. Although analysing large datasets can be time-consuming, the features of the fuzzy clustering algorithm greatly assist in making high-quality decisions. © 2025 Eko Wahyunanto Prihono, Haryanto Haryanto & Sudji Munadi; published by UIKTEN.
