One of the major tasks of elementary school teachers in line with K-12 basic education curriculum is to keep academic records of pupils, which encompasses computing grades, generating reports like Form 137, encoding, storing, retrieving, and editing. These activities are considered in designing the features of the software. This study focused on the development, validation, and testing of an online grading system for Agoo West District, Division of La Union, Philippines. Descriptive and applied methods were utilized. Rapid Application Development (RAD) model was used in the development of the software. Usability questionnaires were used for gathering data. One sample t-test was applied to test the degree of significance of usability. Findings reveal that the software was highly valid in terms of functionality and automation. Furthermore, the software was highly usable as to content, organization, readability, navigation, user interface design, and performance and effectiveness. Moreover, the usability of the software was significant. Hence, the developed software is valid and usable.
