The Education High School (EHS) is a separate institution from the UST High School. EHS was established to give quality Catholic education to those deserving students who cannot afford to pay the fees required by other schools. It also serves as the training ground for fourth-year BSE students at the College of Education. This laboratory school was established during the time of Rector Magnificus, Rev. Fr. Angel De Blas, O.P. with the help of the Dean of the College of Education, Rev. Fr. Aurelio Valbuena and Mrs. Caridad Z. Sevilla, the EHS principal and the different critic teachers of the College of Education. Classes commenced on August 1, 1950.

A number of faculty members from the College comprised the first set of critic teachers for the different subject areas in the EHS. They were: Dr. Mercedes G. Santamaria, Dr. Clemencia J. Colayco, Dr. Rosario D. Bondoc, Miss Concepcion Leonor, Mrs. Antonia P. Villanueva, Miss Consuel Perdices and Miss Nina Custodio.

The first regular teachers were Miss Concepcion Alba, Mrs. Salud P. Belmonte, Mrs. Salome Castillo, Miss Rosario Mauricio, Miss Lourdes Z. Sevilla and Miss Teresita R. Villamil.

There were 361 students in the first enrolment of the EHS. There were ten (10) sections in the first year, two (2) sections for the second year and two (2) sections for the second year and two (2) for the third year. Half of those sections were attended in the morning by girls, half in the afternoon by boys.

In order to give authentic religious and practical leadership training and to strengthen unity and cooperation among the students, religious and secular organizations were founded. Among them were Student Catholic Action Units for the boys and girls and the Knights of Jesus for the Boys. Mr. Arturo De Leon served as their Adviser. The Boy Scouts were adopted to give some training to male students.

Through the years, the EHS has been in the forefront of championing the cause of Catholic education in the Secondary School level. As the University of Santo Tomas enters its 405th Year, the EHS will continue to put premium on developing competence, commitment, and community involvement coupled with the core values of patriotism, respect, piety, responsibility, simplicity, honesty, integrity and justice among its students.

The Education High School seeks to evolve into one of the leading Catholic secondary institutions of learning in the country by strengthening and revitalizing the curriculum, faculty updating, and networking with other institutions in the educational community.

Education High School commits itself to the task of participating in the evangelizing work of the Church by providing students with quality Catholic Education and by imbuing with the virtues of truth and love as espoused by the Angelic Doctor, St. Thomas Aquinas.

Dignity, Honesty, Justice, Piety, Respect, Responsibility, and Simplicity 

The seal of the UST Education High School represents the eight core values of the school. These core values are also the name of the sections for Grade 7-10.
