Abstract

The 2025 Vietnamese National High School Graduation Exam introduces a new three-format structure (multiple choice, True/False, short answer), while still relying on traditional OMR answer sheets that often lead to mechanical errors. This study proposes an AI-assisted grading system combining a direct-answer sheet format with Mathpix OCR handwriting recognition to address these limitations. Using a five-stage simplified Borg & Gall model—regulatory analysis, system development, expert validation, dual-phase trials, and pilot testing on 93 student papers—the system achieved 98.5% character recognition accuracy and high user satisfaction (Likert ≥ 4.0/5) in reducing errors and supporting all question types. Findings show that AI-enhanced direct-answer formats maintain OMR-level reliability while improving test validity. A proposed implementation roadmap includes expanding handwriting datasets, standardizing 300 dpi devices, province-wide teacher training, and integration into the official grading process.
