The study utilized the descriptive-correlational research design and used a questionnaire as the main instrument to gather the necessary data to answer the specific questions of the study. Stratified sampling was employed to determine the respondents of the study using the universal sampling. Mean and standard deviation were used to determine the extent of ancillary function, extent of self-efficacy, and the extent of resilience of the teachers. The study revealed the following significant findings: The teachers were almost always involved in ancillary functions with extra-curricular ancillary functions having the highest mean rating. They had a high extent of self-efficacy and resilience with interaction having the highest mean rating and problem-solving had the lowest mean rating. Moreover, coping self-efficacy and task self-efficacy were statistically correlated with the extent of resilience of the teachers. The higher is their self-efficacy the higher is their resiliency to adversities in their workplace. The extent of co-curricular and extra-curricular ancillary functions had no significant relationship to teachers resilience level.
