California Prep International School (California Prep or CA Prep or CPIS) was co-founded by Dr. Phakdee Mangmiwatthana (Ph.D.) and Dr. Adelino Libato (Ph.D.) on November 14, 2010.

California Prep is committed to the harmonious development of the whole person for student excellence in academics, character/personality, useful service, and global citizenship. Moreover, it intends to continue its tradition of being among the first two complete e-learning international schools in Thailand which were pioneered by the California Prep Team. California Prep stresses the Core-subjects (Math, Science & English plus Business) with e-Learning plus Talent Development and Self-discipline/Values. The ultimate target is character development with positive attitude and love to mankind and the Most Powerful Spirit or Creator God.

It would have been impossible for California Prep to survive without God's blessings and unimaginable synergy through the family of the late Mr. Bhai Khan Mariam Pongswang. The unwavering support and generosity of the said family through Khun Malinee (Khun Chit), Dr. Hataishanok (Dr. Nok), and Khun Manuschanok (Khun Nat) made the new strategically located campus at Kaeng Khoi (Saraburi) possible. This 17-rai campus and its renovated buildings just perfectly match the vision and dreams of the founders.

Among the first School Board members were Dr. Hataishanok Pongswang, one of the directors at Mitrapap Memorial Hospital; Khun Pom Polcharoen, shareholder of Thongsomboon Club; and Dr. Gideon Samson, Investor representative from CA, USA. Among the first leading personnel of California Prep were Nuengnalin Tawinno, M.A. ongoing (Deputy Director for Operations & PR); James Barrett, M.A. (Deputy Director for Curriculum); Nuttida Intasong, M.A. (Registrar); Jongrak Phenglia, M.A. (Librarian); Russell Rollan, M.A. ongoing (Middle School/High School Head); Ajarn Jidapha Tawinno (Cafeteria Head); Michael Alcaide (IT Administrator); Alex de Guzman, M.A. (IT/elearning consultant).

Other Pre-Construction Pioneers: Michelle Alcaide; Daniela Assimiti; Charity Libato, M.A.; Mervin Gallo; Wichuda Jongjit; Del Libato; and Janet de Guzman, M.A. (Elementary Level Consultant); Meenawan Kadeerak, Anuwat Kadeerak, Celedonio del Rosario, Charidel Libato, Olga Sorokina del Rosario, & Bhahanan Jongjit.

Post-construction pioneer teachers/staff of California Prep were: Juby Arceo, & Pichit Thanthra. Moreover, some personnel were also granted honorary pioneer status such as: Bernie Bugaay (part-timer), Roland Ladrido, Daniel Ramos, Ganee Escondo, Arlene Gabida, and Aysha Abdur Rahman.

At the pioneering years, Dr. Phakdee Mangmiwatthana served as the School Director and Licensee while Dr. Adelino Libato served as the Board Chair and Vice-Director for Academic Administration.

Our school uses the California Department of Education (CDE) curriculum. The reason is obvious. California appears to have similar contexts to Asia in the sense that there are many non-native English speakers living there. The mixture of cultures and people from various nationalities in California provide a setting that’s closer to Asia. In fact, the CDE curriculum has a Language Development component which may be equated with the ESL program in many international schools.

Moreover, many parents in Asia and/or Thailand still look up to America as a model for excellence and prestige. This perception will continue to prevail even in the next few years. Undeniably, when it comes to great inventors, America has produced a lot of them. This may be due to the emphasis on creative imagination and problem solving skill. In addition, USA is still considered as the leading economy of the world with its unbeatable military power which may be attributed to the superiority in technology and scientific leaps.

It should be noted that the written CDE curriculum is delivered with the contextual considerations. The school does not just uproot the CDE curriculum and transplant it here in our contexts. Our qualified and experienced teachers, most of them are MA degree holders, have been trained professionally to ensure that the environment is supportive and caring to boost the student learning. This environment is enriched with various student activities such as field trips, retreats, camping, cultural celebrations, and others. Our curriculum delivery is normally supported with e-learning modality and mastery learning approach with student-centered paradigm.

Our academic model underscores our three-pronged emphasis such as: Core subjects with IT; Self-discipline or Self-control; and Talent development. These are our niches and we want to be known as the best on these three dimensions plus a BIG NO to smoking, alcohol, and drugs. Our high school streams include the following: Business/English; Business/Computer; and Math/Science. However, those seniors whose GPAs don’t qualify may be granted the General Diploma. It may take years and years to fully deliver and fulfill the mission statement. But we will get there!

Our broad curriculum (beyond the written one) may be squeezed and the delicious juice that will come out is balanced education. It implies something more beautiful that the traditional emphasis of head, heart, and hands. To our level best, we dream that our students may develop mentally, physically, socially, and spiritually/morally. This will be done from standpoint of multiculturalism where everybody is accepted, respected, tolerated, and loved regardless of religious affiliations, nationalities, and colors. In brief, we want our graduates to be among the best or better than the rest!


California Prep is committed to the harmonious development of the whole person for student excellence in academics, character/personality, useful service, and global citizenship. Moreover, it intends to continue its tradition of being the 1st complete e-learning international school in Thailand. California Prep stresses the core subjects (English, Math, Science, & Business) with e-Learning plus the Talent Development and Self-discipline/Values.


With highly qualified and loving mentors, California Prep has positioned itself to deliver its American-based curriculum which has recognizably well-crafted content standards. California Prep curriculum demands the best practices, high involvement, and serious engagement of the stakeholders. Through the collaborative efforts of the teachers, parents and the community, California Prep cannot fail in professionally delivering its mission, standards and objectives. High expectations are set upon teachers and students with respect to continuous improvement in communication skills, creative imagination, contagious positive mental attitude, and contribution to society.

Hence, high student learning is the bottom line with emphases in the practical realities of life and problem solving skills so that the best in the students will be honed. Proper choices and creative imagination that links with the spiritual realm may lead them to happiness and success. This finds expression in the burning desire to cherish and pursue the divine mission to serve even the disadvantaged. This contextualized Western curriculum will bring value-added twists and flavor that impacts society in general through the transformation of the head, heart, and hands for the new generation with a new spirit!
