Project-based Learning

High school students discover new capacities for critical thinking and forming independent judgments. Students become financially literate in the Canadian system, learn to open their own business, use technology to their best advantage, read classics and explore scientific concepts. Classes debate ethical issues in science, history, economics and literature. Students write poetry, engage in a variety of mathematical reasoning, inquire, hypothesize and conduct hands-on lab experiments. Our teachers present demanding, open-ended topics that encourage students to observe, compare, analyze, create, question and imagine alternatives. They then help students understand why those concepts are important and how they can be applied in the real world. By combining theory and practice through our co-op and regular day program, students gain a true understanding of the world around them.

English Enrichment

There are five ESL courses that are based on levels of proficiency in English. Depending on learners' previous experience with English, students may be placed in ESL Level 1, 2, 3, 4, or 5. Students of Grade 9 age whose initial assessment indicates that they are beyond ESL Level 4 (ESLDO) will be placed directly in Grade 9 Applied English (ENG1P) or Grade 9 Academic English (ENG1D). 

Students' level of English is assessed during an interview and when necessary, supplemented with an English Assessment Test. Based on the results, students will be placed in the appropriate level of English class.

Flexibility & Focus

Keystone International Schools have a two-semester system offering a more flexible academic schedule. 

Typically, students take 4 credits during the first semester and 4 credits during the second semester. If needed or desired, students can also take up to 2 credits during the Summer semester. 

Classes are ninety minute blocks. By studying courses in ninety minute blocks, and only having to take maximum of  four subjects per semester, students are able to concentrate on fewer courses at a time, resulting in less stress and more time to focus on their courses. Students get individual help and support from teachers.  

This type of academic schedule, which is more aligned with college and university system prepares students for higher education.
