This study aimed to determine the level of instructional capability of the public elementary school teachers in Calasiao District I during the school year 2019-2020. The teachers’ level of instructional capability as perceived by the Master Teachers is “Capable”. Likewise, the teachers themselves perceived that their level of instructional capability is “Capable” along the domains of Content Knowledge and Pedagogy, Learning Environment, Curriculum and Planning, and Assessment and Reporting. However, the teachers rated themselves as “Moderately Capable” in terms of Diversity of Learners. Teachers encounter “Serious” classroom management – related problems which need to be addressed by the teachers themselves and school administrators. Teachers’ level of instructional capability is not associated with the extent of seriousness of classroom management related problems they encounter.
