Ramaswami and Bhaskaran [11] have constructed a predictive
model called CHAID with 7-class response variable by using
highly influencing predictive variables obtained through feature
selection so as to evaluate the academic achievement of
students at higher secondary schools in India. Data were
collected from different schools of Tamilnada, 772 students’
records were used for CHAID prediction model construction.
As a result, set of rules were extracted from the CHAID
prediction model and the efficiency was found. The accuracy of
the present model was compared with other models and it has
been found to be satisfactory
