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.
