Its programs emphasize in the English, Filipino, and Mandarin Chinese languages, Mathematics, Science, and Information Technology.

For 15 years, Mr. Chow Cing Chian, Mr. Tsai Xiang Chang, Mr. Tiu See Eng, Mr. King She Hiong, Mr. Shu Seng Shan, and Mr. Huang Meng Kuei served as school principal one after another.

Huang and Sy Eng, the president of the Educational Association and at the same time the chairman of the board of trustees, efforts were exerted and donations from various sectors of the Chinese community were gathered.

But with the changing of times, both the Manila and the Caloocan campuses started offering pre-school and elementary education during the 70s.

In 1978, the Alumni Association successfully assisted the board of trustees in the fund raising campaign for the expansion project of the Caloocan campus.

In the 1980s, the Board of Trustees, the Alumni Association, and the school authorities realized the imperative need for further development in order to meet the demands of the changing times.

Taking the suggestion of the principal, Mr. Go Seng Guan, the reconstruction of the school building in the Manila campus started under the leadership of Mr. Chung Tiong Tay, the chairman of the board of trustees.

After five years of patience and hardwork, a towering new school building proudly stood along Jose Abad Santos Street.

On January 11, 1986, while the construction of the main school building was on its peak, Mr. Go Seng Guan died.

After the completion of the new school building, the president of the Alumni Association, Mr. John Tan, spearheaded the fund-raising campaign for the “PCHS Faculty and Staff Mutual Aid Fund”.

In 1989, the Board of Trustees organized the PCHS Educational Foundation to ensure the effective management of these endowments.

In 1990, realizing that the quality of Chinese education had deteriorated, and that the instructional materials had become old and obsolete, Mr. Chung Tiong Tay, the chairman of the board, used his personal money to hire experts to revise and prepare instructional materials that would suit the needs of the local students.

With this, Mr. Gan introduced “Teaching / Learning Chinese as a Secondary Language”, the latest pedagogy developed specifically for non-native speakers.

In 1991, spearheaded by the several members of the board of trustees and directors of the Alumni Association, the Philippine Chinese Education Research Center was established.

After Dr. Chuang Chong Chian, the Alumni Association went under the leadership of Mr. Ang Cheng Tionsu, Ms. Bee Keng Elena Cu Uy Gam, Mr. John Tan, Ms. Mary Lim, Mr. Eduardo Chua, Ms. Pilar Ongking, Dr. Tan King King, Ms. Janet Kopio, Mr. Alfredo Lu, Mr. Peter Gaisano, Mr. Sy Uliong, Mr. Angel Tan and the incumbent Ms. Diana To.

The Board of Trustees passed a resolution to construct a modern 4-story Kindergarten Building on the Caloocan campus.

After more than 30 years of selfless dedication to his beloved alma mater, Mr. Chung retired as the chairman of the board of trustees in May 2000.

Both parties have established a long term relation, interacting regularly, helping each other towards the continuous improvement of their educational standards.

In 2006, Ms. Bee Keng Elena Cu Uy Gam succeeded Mr. Eduardo Chua, and became the first female chairman of the board of trustees.

In 2008, Ms. Pilar Ongking succeeded Ms. Bee Keng Elena Cu Uy Gam as the chairman of the board of trustees.

On the same year, Mr. Angel Tan succeeded Ms. Pilar Ongking as the chairman of the board of trustees.
