Ages 15 – 18 Years

Our mission is to foster the development of well-adjusted individuals through International Baccalaureate principles thereby promoting the physical, intellectual, emotional, and spiritual needs of the children, staff, and parents who meet, work, and learn here. Our students are inspired to be active, responsible global citizens and well-prepared to work towards achieving a better world. 

The high school curriculum is designed to foster the students’ curiosity and eagerness to learn, and help them find a sense of belonging in the increasingly complex and interconnected world around them. The curriculum is based on an integration of the current research in human development and the skills needed for a productive life in the twenty-first century.

The goal of the program is to empower adolescents by providing opportunities to be academically challenged and competent, gain self-confidence and self-knowledge, learn to be adaptable, and to create a vision for their personal future.

With a strong focus on academics, social development, effective communication, and acclaimed International Baccalaureate Diploma Programme (for ages 16 to 19),  students will be well-prepared for success in college or the workplace depending on their aspirations. Students will regularly collaborate with local community members and experts, ranging from local business leaders and community officials to organic farmers. Starting in 7th grade, students begin to gain experiences in the work environment. These experiences gradually grow into full-fledged internships or apprenticeships once they reach high school.

What Is the International Baccalaureate® (IB) Diploma Programme (DP)?

The IBDP is an academically challenging and balanced programme of education, with final examinations, which has proven to prepare students aged 16 to 19 for success at a university and in life beyond. This unique program is internationally recognized as representing one of the highest standards in university preparatory education. More than 1,000 colleges and universities in North America have recognition policies on how they weigh it in admissions, advanced standing, college credit and scholarships.

The International Baccalaureate® 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 organization works with schools, governments and international organizations to develop challenging programmes of 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.

IBDP students must:

  • Choose one course from each of five subject groups delivering a breadth of knowledge and understanding in language and literature, individuals and societies, the sciences and mathematics. DP courses can be taken at higher level (HL) or standard level (SL).
  • Choose either an arts course from the arts group, or a second course from one of the other subject groups.
  • Earn a minimum score of 24 points (out of 45) to earn the Diploma.

In addition, the DP core is comprised of theory of knowledge (TOK), creativity, activity, service (CAS) and the extended essay (EE).

  • The EE requires students to engage in independent research through an in-depth study of a question relating to one of the DP subjects being studied.
  • TOK develops a coherent approach to learning that unifies the academic disciplines. In this course on critical thinking, students inquire into the nature of knowing and deepen their understanding of knowledge as a human construction.
  • CAS complements a challenging academic programme in a holistic way, providing opportunities for self-determination, collaboration, accomplishment and enjoyment. It involves students in a range of activities alongside their academic studies throughout the DP.

Montessori at Sharon Springs is a candidate school* for the Diploma Programme. This school is pursuing authorization as an IB World School.

IB World Schools share a common philosophy- a commitment to high-quality, challenging, international education- that we believe is important for our students.

*Only schools authorized by the IB Organization can offer any of its four academic programmes: the Primary Years Programme (PYP), the Middle Years Programme (MYP), the Diploma Programme (DP), or the Career-related Programme (CP). Candidate status gives no guarantee that authorization will be granted.
