The study looked into the level of competencies of classroom teacher- counselor divided into behavioral competencies and work-related competencies and the level of student’s self-esteem as indicated by identity, appreciation, acceptance, self-confidence, pride, humility and selfishness. The study used descriptive correlational design. For the academic year of 2021-2022, 147 Grade 11 and Grade 12 Humanities and Social Sciences students of Tanauan Institute Inc. took part in the survey. The findings revealed that the classroom teacher- counselor competencies and students’ self-esteem had a substantial association. Based on the findings students may directly share their concerns with their teacher-counselor dealing with personal issues affecting their general well-being and academic progress. They may learn to participate and feel more connected to the adults in their lives. Furthermore, teachers may foster and create a supportive environment that can strengthen students' emotional and social learning capability, focusing on solving problems and making decisions, building relationships and understanding social situations, and understanding oneself and one's emotions. Finally, continue to support the needs of teachers and learners when it comes to the self-esteem of students, which leads to academic success. Strengthening the competencies of teachers–counselors reassure the students' mental health.
