Tess Baguio is the Principal of Small World Christian Kindergarten. Initially a chemist by training, Tess was inspired to change career directions to the field of education when her daughter entered Small World Christian Kindergarten in 1998. Having found her calling to teach and serve young children, Tess studied the Montessori Method from Montessori Teacher Preparation of Washington (MTPWA), and then qualified as a Kindergarten teacher with Hong Kong Institute of Education. She has completed two Post Graduate Diplomas in Education, specialising in Special Education (2010) and Early Childhood Education (2014) and subsequently completed her Certificate Course for Kindergarten Principals at HKBU (2015). She received her Masters Degree in Education (Early Childhood Education) from the University of Hong Kong in 2019.

Attracted to Small World by its biblical foundations and Montessori philosophy, Tess joined the school as a teacher in August 2001. She led the kindergarten as Vice-Principal in 2010 and as Principal in 2011. Tess believes that all children deserve equal opportunities to access the education offered by the school and to reach their true potential. Tess has lived in Hong Kong for over 20 years with her husband and their four daughters.
