Led by Preschool Co-ordinator Vivian Qian, our preschool teachers are an exceptional team of highly qualified and experienced early childhood educators. All our teachers are native speakers of either English or Mandarin. They meet high standards for education with degrees, permits and/or more than the state-required Early Childhood Education (ECE) units of study. Our preschool teachers average nine years of teaching experience. More than half of all preschool teachers have been with YCIS Silicon Valley for over six years.
