Our preschool programme strives to facilitate the transition of 2 to 3 year olds into the IB Primary Years Programme. At this age, our prime focus is to build confidence in every child so they can express themselves freely. Once a child can express herself or himself, it opens the gateways to the path of understanding, knowledge and learning.

Mark Twain International School has been my educational haven since the tender age of 6. Now, navigating the second year of the diploma programme, my academic journey spans from delving into computer science to embracing the world of arts, particularly music. Being an active member of the musical theatre club has allowed me to showcase my talents on stage, thanks to the school's commitment to providing opportunities for students. The experience at Mark Twain goes beyond the curriculum. Engaging classes led by passionate teachers have made learning a joy. Mark Twain is more than a school; it's a second home where the warmth of belonging lingers. The plethora of opportunities the school offers has been instrumental in shaping my growth, leaving me with a reservoir of memories and skills that will stay with me throughout life

Andreea, DP2

Mark Twain International School was my home for 12 years and continues to be a place I hold very dear to my heart. It is a community that nurtures excellence, self-empowerment and growth on both academic and personal levels, where the individual is viewed and appreciated as a whole. However, for me, Mark Twain is about the people - teachers and directors whom I daresay have become my family, my friends, people who I know will always welcome me with open arms and sincere smiles, people I look up to, who have guided me and shaped me into who I am today. Thank you, Mark Twain
