Academic Programs

While all schools in the Five Star District follow a common and comprehensive curriculum, our school also offers some unique academic programs:

IBO (International Baccalaureate Organization) Mission Statement:

The International Baccalaureate Organization 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 school, governments and international organizations to develop challenging programs of international education and rigorous assessment. These programs encourage students across the world to become active, compassionate and lifelong learners who understand that other people, with their differences, can also be right.

Thornton High School will welcome its first class of “whole school” IB/MYP students in the 2015-2016 school year.  Essentially all 9th graders will enter as IB students and be given a choice to continue (via the Diploma program) in their junior year or choose an alternative pathway to graduation.  It is important to note that the International Baccalaureate is a world renowned approach to learning that aims to develop internationally minded people who, recognize our common humanity and shared guardianship for the planet.  IB learners strive to be:  Inquirers, knowledgeable, thinkers, communicators, principled, open-minded, caring, risk-takers, balanced, and reflective.  Students graduating with an IB Diploma can potentially earn up to 24 college credits.
