Naïve Bayes Classifier-Based Intelligent System for Student Academic Performance Assessment
Bibliographic record
Abstract
This study proposes the design and implementation of an intelligent academic performance assessment system based on the Na ve Bayes Classifier algorithm.The system is developed using PHP and MySQL and is architected with a lightweight and modular structure tailored for school environments with limited technological resources.It integrates a classification engine capable of processing diverse academic indicators, including test scores, attendance records, and behavioral data, to classify students into performance categories (low, medium, high).Compared to conventional assessment methods that often rely on manual judgment and are prone to inconsistency, this system offers a data-driven and objective alternative that supports evidence-based educational decision-making.Across ten testing iterations, the system achieved an average classification accuracy of 96.67%, demonstrating its predictive reliability.Moreover, user evaluations involving 230 respondents (teachers and students) reported an overall satisfaction rate of 86.8%, indicating strong acceptance in terms of usability and effectiveness.The study highlights the advantages of Na ve Bayes over more complex algorithms such as XGBoost and neural networks, emphasizing its ease of interpretation, computational efficiency, and practical deployability in real-world educational contexts.The system's predictive outputs enable early identification of students requiring academic intervention and support differentiated instruction, ultimately contributing to the enhancement of personalized learning pathways.These findings reinforce the role of machine learning, particularly interpretable and resource-efficient models, in transforming traditional assessments into intelligent and scalable educational solutions.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
