The growth of academic data size in higher
education institutions increases rapidly. This huge volume of
data collection from many years contains hidden knowledge,
which can assist the improvement of education quality and
students performance. Students’ performance is affected by
many factors. In this study, the data used for data mining were
students’ personal data, education data, admission data, and
academic data. NBTree classification technique, one of data
mining methods, was adopted to predict the performance of
students. Several experiments were performed to discover a
prediction model for students’ performance. The class labels of
students’ performance were students’ status in study, graduates
predicates, and length of study. The experiments were conducted
with two-level classification, the university level and faculty level.
The resulted model indicated that some attributes had significant
influence over students’ performance.
