Abstract
This study aims to determine the different auxiliary functions affecting the productivity rate of public elementary school teachers in Buluan District, Division of Maguindanao-1, BARMM, Philippines. Using a descriptive-correlational research design, data from 102 teachers from nine schools were collected through a validated survey questionnaire. The study focused on the teachers' auxiliary roles, classified as curricular (i.e. lesson planning, coordination with community and research) and extra-curricular (i.e. coaching in sports, feeding programs and school canteen management), and their influence on the dimensions of work performance (instructional planning; involvement in professional growth and interaction with the community). The results of the study revealed that teachers have prominent functions, with a grand mean of 4.33 indicating their wide involvement in curricular and extra-curricular activities. Although the workload increased, teachers excelled in stated measures, explicitly instructional planning and community organizing. It was further established that for teachers, ancillary functions showed a significantly positive relationship with their work performance which means that the two variables are interlinked. The findings underscore the tensions between ancillary functions, which have been viewed as enhancing the professional skills of teachers and their involvement in their communities, and balancing the workload against instructional efficiency. Recommendations also advocated for the equitable sharing of ancillary functions, improved technical support from school heads, and recognition programs to motivate teachers and sustain high performance levels.
