This study aimed to develop a guidance support system software application that can secure and automatically store files and students’ record in the guidance center and to improve the manual process of gathering, segregating, and organizing forms administered by the Guidance Counselor. It also aimed to evaluate the system using the ISO 9126 Criteria for Software Quality to test its performance and efficiency. The software development process using the evolutionary prototyping method was used in the development of the system following several stages of system development. The descriptive method was used to interpret the result of the evaluation. The system was evaluated by IT Experts who are in line with database development and programming. Mean and standard deviation was used to interpret the result of the evaluation. The overall result of the evaluation was 4.06 which implies that the system has a very good performance and it met the criteria for software quality. Recommendation for the full implementation of the system and active involvement in the effectiveness of delivery and further mainstreaming of these services were also given.
