Student development evaluation at Harapan Hamparan Perak Senior High School has been conducted manually without systematic pattern analysis. This study analyzes the relationship patterns between extracurricular participation, attendance levels, and academic achievement using the Apriori algorithm. Data from 545 students in grades X, XI, and XII were processed using WEKA 3.8.6 with a minimum support of 0.2 and minimum confidence of 0.6.
