The CHAID prediction model was useful to analyze the interrelation between variables that are used to predict the outcome on the performance at higher secondary school education. The features like medium of instruction, marks obtained in secondary education, location of school, living area and type of secondary education were the strongest indicators for the student performance in higher secondary education. This CHAID prediction model of student performance was constructed with seven class predictor variable, whereas the earlier models in reviews were constructed with limited class predictor variables.
