Computer Site Institute is an institution accredited by TESDA that offers Technical and Vocational Education and Training Programs (TVET) to its residents who wish to learn skills but cannot afford formal education. These TESDA Training Courses offered in Laguna are mostly skills training courses with NCI to NCIV qualifications giving its graduates with additional qualifications when applying for jobs not only in the country but internationally.
Before it became Computer Site Institute, it was an idea conceived by REA Realty and Development Corporation in 1987 headed by Mr. Ricardo Aguilar and Mrs. Ana Aguilar to put up a computer school in their town, San Pedro, Laguna. They franchised Metrodata Computer School which offered short-courses that were in-demand at that time; this was under the management of Mr. Edilberto Aguilar. In 1992, Mr. Eliseo Aguilar took place as School Director, at a time when computer schools began to grow in number in San Pedro as well as in other municipalities nearby. As the pioneer computer school, they remained competitive and still managed to become one of the outstanding schools.
In the year 2000, under the management of Mr. Eliseo Aguilar, the board met to establish a new school name, and cut the franchise from Metrodata Computer School, and then the Computer Site Institute Inc. was born. They offer 5 computer courses namely Computer Management, Computer Information Technology Secretarial, and other in-demand and up-to-date short courses for Computer Programming, Computer Technology, and Computer better services. It started to extend its generosity to give education to low and middle-income families by offering free tuition fees.
