Most faculty inherently believe that students who frequently miss class significantly increase their likelihood of poor grades by doing so. The purpose of this research was to develop a Probabilistic Neural Net (PNN) based Genetic Algorithm to assess the relationship between absenteeism and student grade performance in a structural systems course taught by the author. The model was trained to classify the outcomes (pass/fail) of 130 students using records of class attendance and end-of-course

It was found that course attendance and grade performance were positively correlated. The model was then used to accurately predict the success rate of a new group of 80 students based on provided attendance records. Overall, this research shows that the developed PNN based GA model can be used to predict the outcome of student performance in the structural systems class based on anticipated class absence patterns.
