Competency Discovery System: Integrating the Enhanced ID3 Decision Tree Algorithm to Predict the Assessment Competency of Senior High School Students

Jestoni Vasquez, Benilda Eleonor Comendador


The study presents the development of Competency Discovery System, which integrates enhanced Iterative Dichometer 3 (ID3) decision tree algorithm, to predict assessment competency of senior high school students. It was also successful in integrating the feature selection to select the data attributes that have impact on the performance of students. Pre-processing of data collected from school database and available spreadsheets was performed to determine the attributes that may possibly influenced the students’ competency assessment. It provides a decision tool for teachers to enhance students’ performance, particularly in the academic and technical aspect, based on factors that might affect their learning process. The academic and technical performance is often used for predicting the learning behaviour of the students and can be a crucial factor in building their better future. Moreover, the system identifies students that were likely to fail, and that may need assistance in view of the National Certificate programming-related assessment. The National Certificate assessment aim to regulate the students can perform to the standards expected in the workplace based on the defined competency standards. Passing the competency assessment shows that the students is ready to join the labour workforce. Predicting the future outcomes based on the historical records can help the teacher guide the students’ assessment performance. This is also beneficial to students as they have the opportunity to prepare for taking the assessment. Majority of the participants assessed the software as 'highly acceptable’ with support on its implied functions in terms of reliability, efficiency, usability, security, and user-friendliness.
