Bulusan High School started in 2000 in a rice field at Dancalan, Bulusan, Sorsogon with only one temporary building made of wood and nipa for freshmen. It was nicknamed 'Laboy' by the locals because it is in a very muddy paddy and it exemplifies its humble beginning. The lot was donated by Albertini Montenegro Jr. who headed the school for five years. It was followed by a three-room semi-permanent building donated by the local government through the town's mayor, Hon. Juan G. Guysayko to accommodate the surging enrollment. The school was recognized by the national government through House of Representative Bill No. 3361 authored by Jose Solis through committee report 245 co-authored by Lagman and De Guzman. Due to absence of public secondary school in Bulusan town proper other than that offered by Bulusan National Vocational and Technical School which could only accommodate a few qualified students, young Buluseños enrolled at San Roque and Dr. Espeña High School and even to neighboring towns. In the vicinity of Bulusan Poblacion there was only Jose S. Reyes Memorial Foundation School, a private institution, which offers secondary course. Later, the Immaculate Heart of Mary School offered the same. Albertini Montenegro Jr. was replaced briefly by Veronica Gallanosa as teacher-in-charge, followed by Mirando Fajardo. In 2006, Ave E. Mendizabal took over as the first school principal. The first commencement was held March 2003.
Bulusan National Vocational and Technical School integration
In 2002, the Department of Education ordered the TESDA-sponsored Bulusan National Vocational and Technical School to turn over its high school department to Bulusan High School. A group of students, mostly juniors and seniors, and five secondary school teachers added to the enrollment and staff — making a steep increase of its population.
Extension
In 2006 Bulusan High School made another extension at Barangay Poctol, Bulusan, Sorsogon, at the back of Bulusan Central School, to accommodate a very high volume of enrollees: mostly freshmen.
Publication
The school paper at the start was named The Dawn by advisers, Sheila Marie Dino and Anita Fulo. In 2006 when Joel France and Circe Gegajo managed the school publication and news conferences the name was changed to Bulos Aguingay due to the similarity of The Dawn from other school paper in Region V. Aguingay was a very popular name in Bulusan, a legendary mistress of a hero named Bulusan himself. A vast rainy day lake in the middle of Bulusan Volcano National Park is called Lake Aguingay. Bulos is taken from the name of the town Bulusan which means "to pour water." Bulos means "water surge." From these names the school approved Bulos Aguingay as its official publication in English and in Filipino. Student-staff of the publication have garnered awards from local, division, and regional press competitions and conferences.
Curriculum
Pursuant to its recognition, Bulusan High School offers general secondary education of Basic Education Curriculum as mandated by the Department of Education of the Philippines.
