The High School Department of Colegio de San Juan de Letran, which has existed for almost four hundred years now, has established its name as one of the most well-known secondary schools for boys in Manila. 

Through all these years, it has produced a number of graduates who have made a name in the different fields- business, sciences, medicine, politics, entertainment, sports, arts, and many others.  This is just an indication of the school’s ability to prepare and mold their high school graduates in the Dominican way of becoming integral persons who are ready to face the challenges of tertiary education in any field and eventually emerging into world class professionals.

At present, the Letran High School continues to put premium on the quality delivery of its educational services as it continuously works for the improvement and upgrading of its material and human resources. Now one of the pillars of the Basic Education Department of the Colegio, the other being the Elementary Level, the Letran High School has extended the offering of quality education to high school girls when it opened its doors to Lady Squires during the school year 2005-2006 in the First Year and during this school year 2006-2007 in the First and Second Year Levels.
