This study sought to determine the relationships between the used learning management system and the instructional proficiencies of teachers in private schools. A researcher-made survey questionnaire was administered to extract data from the one hundred eight (108) respondents in eight (8) private schools in the Municipality of Calauan. The study shows that the assessed use of a learning management system was significantly and positively correlated with the level of instructional proficiencies and their level of technical competence. Therefore, the hypothesis stating that there is no significant relationship between the instructional proficiencies of the teacher-respondents and the use of LMS features and their level of technical competence is not sustained.
