Before, there were only two existing public high schools in the municipality namely Imus National High School and Gen. Emilio Aguinaldo National High School which initially served 11, 776 students with a ratio of 1:98 for every class. The Gen. Emilio Aguinaldo National High School, the mother school of Gen. Emilio Aguinaldo National High School – Annex is 5 – 6 kilometers away that catered to enrolees coming from Bacoor, Las Piñas, Dasmariñas, and Kawit.

In the year 2007, the rapid increase in the population of General Emilio Aguinaldo National High School – Imus signalled the rise of an annex school situated in Pasong Buaya II, Imus, Cavite. The local government of Imus through the initiative of former Mayor Homer T. Saquilayan and later was carried on by Mayor Emmanuel L. Maliksi, fully recognized the crucial need and the importance of education towards people empowerment, economic progress, advancement, and awareness of the scarcity of 3 academic resources, thus, the General Emilio Aguinaldo National High School – Annex was established.

The access to free education had materialized when former Secretary of the Department of Education, Jesli A. Lapuz approved the request for the opening of Gen. Emilio Aguinaldo National High School – Annex. It started with the Saquilayan building that housed 6 classrooms in a one thousand five hundred sixty five (1,565) square meter property at block 8 lot 21 Hugo Vidal St. Bahayang Pag-asa Phase 10 Pasong Buaya II, Imus, Cavite. GEANHS-ANNEX started with only 247 students and 6 teachers under the supervision of Mr. Jose E. Samson, Head Teacher VI of English.

A special budget for the teachers was obtained from the local government until they were promoted to national items and budget was subsidized by the national government. Since then, supports from different sectors became steady and several improvements were made. More classrooms were built to accommodate the fast increase in the number of students. School supplies, textbooks, and equipment were provided.

Then Mrs. Glenda DS. Catadman, Head Teacher VI of Filipino department of Gen. Emilio Aguinaldo National High School - Imus, came as the new officer-in-charge as Mr. Jose E. Samson, Jr. rose to the position of Principal I at Taywanak National High School.

Through the diligent leadership of Mrs. Catadman, additional teachers were hired. There were active involvement in different division/regional/national seminars, trainings, and workshops. Outstanding students also participated in many competitions and won different awards. This paved way as the school started to be recognized in the academics, as well as in sports. More activities and school events were conducted which also helped in the development of new projects for the welfare of the students and of the whole community.

4 Today, GEANHS-ANNEX has become a school that is continuously expanding and improving not only in physical structures but also in the quality of education being offered to more than a thousand students. The school will continue to prosper as it reaches its full autonomy.

The General Emilio Aguinaldo National High School-Annex envisions high educational standards, quality instruction and an academically stimulating atmosphere wherein each student’s learning potential is maximized and Filipino values are instilled that would make them globally-competitive.
