Tuguegarao City Science High School Was founded by The former mayor of Tuguegarao City, Mayor Delfin Telan Ting. TCSHS separates its students by sections based on the scores obtained at the entrance examination taken before a student is admitted at the first year level in accordance with the country's standard. In 2008-2009, there was no entrance examination for its pioneering batch.
