The study explored the relationship between work-life balance practices and teaching performance of teachers in public elementary schools of Davao Del Norte Division. Also, it investigated the association of the involved variables and the domains of work-life balance practices that significantly influence teaching performance of teachers. With the use of probability sampling, 209 public elementary teachers were selected as the respondents. Utilizing the descriptive correlational survey method, the data collated were analyzed through the use of Mean, Product-Moment correlation and Regression Analysis. Results revealed that there was a high work-life balance practices of teachers and a high teaching performance of teachers among the respondents. Furthermore, there was a significant relationship between work-life balance practices of teachers and teaching performance of teachers. Moreover, all domains of work-life balance practices were found to have significantly influence the teaching performance of teachers. Among the two predictors, individual work-life balance practices demonstrate a slightly stronger influence on teaching performance compared to institutional practices. Based on the findings, it was further suggested that higher officials in the Department of Education and school heads may identify means on how to help teachers reinforce their work-life balance practices which would pave a way in increasing their teaching performance of teachers. More so, future researchers may further explore the involved variables considering other factors and research methods.
