For 40 years now, the Adult Night High School of La Salle Green Hills has been transforming lives through Christian and relevant education.
Guided by the vision of St. John Baptist De La Salle, the De La Salle Brothers founded ANHS in June 1978 to help the marginalized in our society. It started with an enrolment of sixteen students who were mostly the household helpers and drivers of the day school students. On May 13, 1983, the five-year high school program of the night school was given recognition by the Department of Education, Culture and Sports.
In 1989, the Non-Formal Education (NFE) Program, now known as Technical Vocational Education and Training or TVET, was formally established and had seventeen (17) graduates in March 1990.

ANHS underwent Preliminary Visit from the Philippine Accrediting Association of Schools, Colleges and Universities (PAASCU) on January 1997. The purpose of the visit was to evaluate and improve the educational, skills-training and community programs of the ANHS.

In February 1999, after the Consultancy Visit, PAASCU recommended that ANHS was ready for the first Formal Survey. The first formal accreditation was conducted in February, 2000. ANHS was given a 3-year accreditation status, making it the first and only night school in the Philippines to be granted such accreditation. On November 24, 2003, a 5-year accreditation status was given by PAASCU. The second 5-year accreditation was granted on May 25, 2009 which qualified ANHS for Level II accreditation, as certified by the Federation of Accrediting Agencies of the Philippines on June 2009.

In school year 2003-2004, ANHS offered a mainstreaming program for deaf learners in coordination with the city government of Mandaluyong.

ANHS was certified by the Fund for Assistance to Private Education (FAPE) office as Educational Service Contract (ESC) School in school year 2008-2009. It was granted TESDA accreditation as assessment center for its TVET laboratories on February 21, 2013.

Today, ANHS continues to offer two major programs: The Five-Year High School program which prepares students for both college and employment, and the One-Year TVET program, composed of 10 industry-given courses. This Lasallian education can be availed of by the financially challenged for only P325 for an entire school year.

As before, ANHS still brings to the fore two important concerns: the total formation of true Lasallians in the areas of religious and values formation, academics, cultural appreciation and social responsibility; and the continuing provision for employment to help alleviate poverty among the adult learners and their families.

Stories of struggles and success now fill the walls of the school; life stories of its graduates who, from their humble beginnings, have risen to the ranks of professionals and entrepreneurs or those who have successfully joined the workforce.

As it celebrates its 40th year, La Salle Green Hills’ Adult Night High School remains unwavering in its ministry of teaching minds, touching hearts and transforming lives.
