Transfer of Credits

40 hours of Community Service

Every student who begins secondary school must complete a minimum of 40 hours of community involvement activities as part of the requirements for an Ontario Secondary School Diploma (OSSD). The purpose of the community involvement requirement is to encourage students to develop awareness and understanding of civic responsibility and of the role they can play and the contributions they can make in supporting and strengthening their communities.

Keystone International Schools partner with various local community organization and ensures that every student gets a placement that is in line with his/her interests when available.

Provincial Literacy Requirement

The Ontario Secondary School Literacy Test (OSSLT) is a compulsory standardized test for secondary school students in Ontario who wish to obtain the Ontario Secondary School Diploma. The OSSLT is written every year in March in all public, private and Catholic secondary schools in the province of Ontario.

University Placement

Our Mentoring Program

The post-high school planning process, lead by the career counselor, empowers each student to assess their own interests and capabilities, and to think independently about the direction of their life after high school.  


Upon arrival at Keystone, the student is given a career assessment and an education plan is made and this plan is re-visited on an ongoing basis. Administration, teachers and guidance counselors, along with family and faculty, provide resources and a supportive environment, which encourages each student to make the best possible choice for their lives after graduation. The guidance counselor provides resources and support for students and their parents through the university search process with a goal of helping each student find a “best match” university.  

The same level of support is also provided for students who choose to work, travel, or participate in a specialized educational program, gap year, or trade school after graduation. We understand that these are important and personal decisions which take time and attention.
