HIS recognizes the fundamental importance of The United Nations Convention on the Rights of the Child and fully subscribes to the principles expressed in the declaration. As an educational institution it gives particular importance to Article 29:
1. States Parties agree that the education of the child shall be directed to:
a. The development of the child’s personality, talents and mental and physical abilities to their fullest potential;
b. The development of respect for human rights and fundamental freedoms, and for the principles enshrined in the Charter of the United Nations;
c. The development of respect for the child’s parents, his or her own cultural identity, language and values, for the national values of the country in which the child is living, the country from which he or she may originate, and for civilizations different from his or her own;
d. The preparation of the child for responsible life in a free society, in the spirit of understanding, peace, tolerance, equality of sexes, and friendship among all peoples, ethnic, national and religious groups and persons of indigenous origin;
e. The development of respect for the natural environment.’

The Mission Statement aligns with the mission statement of the International Baccalaureate Organisation, which is:
"The IBO aims to develop inquiring, knowledgeable and caring young people who help to create a better and more peaceful world through intercultural understanding and respect. To this end the IBO works with governments and international organizations to develop challenging programmes and international education and rigorous assessment. These programmes encourage students across the world to become active, compassionate and lifelong learners who understand that other people, with their differences, can also be right."
The School aims subsume the IB Learner Profile.
