CEIS, Inc. in Malolos is a subsidiary of Centro Escolar University with Main Campus in Mendiola, San Miguel, Manila and Campuses in the City of Malolos, Bulacan, Makati City and Las Piñas City in Metropolitan Manila.

CEIS, Inc. is a private non-sectarian educational institution with Government Recognition and Government Permit to Operate under the supervision of DepEd District 4 of the City Schools Division of Malolos, Bulacan, Region III, Philippines and an active member school of the Malolos City Private Schools Association (MACIPRISA) and People Management Association of the Philippines (PMAP) Bulacan Chapter.

In 2004, the University’s Integrated School called CEU I.S. was phased out. But in July 24, 2013 CEIS was incorporated to Centro Escolar University as Centro Escolar Integrated School, Inc. located at Km. 44 McArthur Hi-way, Centro Escolar University-Malolos Campus Compound, Brgy. Longos, City of Malolos, Bulacan.

It started to operate in Academic Year 2014-2015. It offers complete K-12 Program or the Enhanced Basic Education of the Department of Education (DepEd) from Preschool (Nursery, Pre-Kindergarten & Kindergarten), Grade School (Grades 1 to 6), Junior High (Grades 7 to 10) and Senior High School (Grades 11 to 12: ABM, HUMSS, & STEM Academic Strands).

With the emerging development in the Philippine Education System, the Department of Education calls for the new scheme, the K-12 program. Thus, the CEU Administration fully supported this program.

In 2016, another milestone was added to the history of Centro Escolar University under the leadership of Dr. Ma. Cristina D. Padolina when the Department of Education approved CEU’s application to offer Senior High School Program. Although CEIS Malolos has been offering Basic Education since 2014, it also offered SHS in 2016.

However, in 2019, the Department of Education granted CEIS Manila and Makati Campus the permit to operate and is now considered as a separate entity. Senior High School offers the three tracks in the following strands: Accountancy, Business and Management (ABM), Humanities and Social Sciences (HUMMS) and Science, Technology, Engineering and Mathematics. (STEM)

CEIS is manned by highly qualified and effective administrators and teaching staff. Its curriculum responds to the 21^st century learning skills and centers on value formation. Likewise, its students are competitive because of its concrete knowledge in Singapore Math and Science and with the adaptation of state-of-the-art technology in both teaching and learning. The SHS students of Centro Escolar Integrated School (CEIS) are equipped with skills for TESDA certification and meet college admission standards.
