Our Mission

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. 

Our Philosophy

California Prep education encompasses the whole spectrum of a person’s experiences and practical realities in this life and even in the hereafter. It embraces the mental, physical, social, and spiritual dimensions to the maximum development possible. In its broadest sense, it even attempts to merge and connect the ordinary minds to the loving Infinite Designer/Spirit to become extra-ordinary young visionaries. Thus, its curriculum integrates natural laws, spiritual values, dignity of man, and success principles. The impact to society will be immeasurable and tremendously irresistible.
