In 1976, the school has decided to move to Barangay Kanluran Bukal for the danger of its closure. A petition from a near private school was filed because of its nearness to the said school. It must be located six kilometers away from the private school (the Lilio Academy). Bukal Barangay High School celebrated its first Foundation Day in 1977. Under the term of Mrs. Brul many changes happened such as the inclusion of Math – Science Curriculum for the cream section. There were sixteen (16) pioneer members who exerted their best to be able to live up the expectation of the Division that time.
