Gen. T. de Leon National High School

Seven classrooms were built through the cooperation and support of the Parents-Teachers Association headed by its president Rodrigo Dimagiba.

Under his administration, a three storey-building with 12 classrooms was donated by the national government through the effort of former second district representative Antonio M. Serapio.

The present administration of David initiated significant changes in physical development, staff improvement, and pursuit of quality education.

[2] The acquisition of the new site is a joint effort of David, former barangay captain Alfredo Caiña, and the members of the Local School Board, which includes mayor Sherwin T. Gatchalian, former schools division superintendent Dr. Alma Bella O. Bautista, and second district councilors Lorena Natividad-Borja and Kate Galang.

The campus is located at the east end part of the Gen. T. de Leon Rd., and near the Torres Bugallion Bridge at Barangay Ugong, Valenzuela.

The main building contains the school library, computer laboratory, garden, audio-visual lecture rooms, and cafeteria.

In September 2024, San Miguel Corporation donated seven 4,305 square meters lots to the Valenzuela LGU for GTDNHS expansion and its 6,169 students.

The development includes the constructions of four-story 16-classroom buildings for 2,880 students and an amphitheater, as a multipurpose event center.
