Can You Still Get an OSSD as an Adult or Mature Student?
/Many adults find themselves at a crossroads, wondering if it’s too late to finish high school. Whether you left school early, moved to Ontario from another country, or simply want to open new doors for your career or education, the Ontario Secondary School Diploma (OSSD) is still within reach — and more accessible than ever before.
At Aubrey Academy, we specialize in helping adult learners achieve their educational goals through flexible, online learning. Our programs are built to meet you where you are, regardless of your age or background.
Understanding the OSSD for Adults
The Ontario Secondary School Diploma is one of the most widely recognized high school credentials in the world. While it’s commonly associated with teenage students in grades 9 through 12, the truth is that adults are just as eligible to complete this diploma — and the Ministry of Education provides specific pathways to support mature students.
If you’re over the age of 18 and have been out of school for some time, you may qualify for what’s known as the "mature student" stream. This designation opens the door to earning credits for your prior experience, education, and training — a process called Prior Learning Assessment and Recognition (PLAR). PLAR can reduce the number of courses you need to complete and help you move toward graduation more efficiently.
At Aubrey Academy, our team walks you through every step of the PLAR process. We help you identify which past work experience, training, or education might count toward your diploma, and we support you with a learning plan tailored to your unique history and future goals.
A Learning Model That Fits Real Life
One of the most common reasons adults hesitate to return to school is time. Between work, family, and other commitments, many feel like there’s just no way to fit high school courses into their busy lives. That’s where our fully online, asynchronous learning model changes everything.
With Aubrey Academy, there are no rigid schedules. You can log in at any time, from anywhere, and complete your coursework at your own pace. This flexibility makes it possible to earn your OSSD without having to sacrifice work hours or family responsibilities. Many of our students complete courses while working full-time or caring for children — and they do so successfully because they’re supported every step of the way.
All courses are taught by certified Ontario teachers who understand the needs of mature learners. Our instructors are patient, responsive, and trained to guide you through course content even if it’s been years since you’ve been in a classroom.
Careers in Canada That Require an OSSD
Completing your OSSD isn’t just about personal fulfillment — it’s a necessary step toward many in-demand jobs and careers in Ontario and across Canada. In fact, a wide range of professions list the OSSD as a minimum requirement for entry or further training.
If you're aiming for any of the following careers, completing your high school diploma is a crucial first step:
Police Officer: Most police services in Ontario require an OSSD before you can apply, along with further post-secondary education or training at the Ontario Police College.
Licensed Tradesperson: Whether you're pursuing a career in HVAC, plumbing, electrical, or other skilled trades, your OSSD is often required to enter apprenticeship programs or apply for certification.
Early Childhood Educator (ECE): Colleges offering ECE programs typically require applicants to have an OSSD before they can enroll.
Nurse or PSW (Personal Support Worker): Admission to nursing and PSW programs almost always requires a completed OSSD, especially for public college programs.
Firefighter: Many firefighting programs require an OSSD as a baseline requirement before additional certifications and physical testing.
Corrections or Border Services Officer: These roles often require a combination of an OSSD and a post-secondary diploma or relevant experience.
Armed Forces or Military Services: While some roles may allow entry with partial high school, an OSSD increases your eligibility, rank potential, and access to specialized training programs.
College or University Admissions: Whether it’s for a diploma or degree, having your OSSD opens the door to applying to public and private post-secondary institutions across Canada.
The bottom line is this: the OSSD is more than a piece of paper — it’s a passport to opportunity in Canada.
Real People, Real Results
We’ve had the honour of working with many adults who once thought graduation was out of reach.
Marissa, a 34-year-old mother of two, came to Aubrey Academy after immigrating to Canada. She had completed high school in the Philippines but didn’t have a recognized diploma here. Through PLAR and online courses in English and Math, she was able to earn her OSSD and later apply to nursing programs in Ontario. “I never thought I’d have a second chance. Aubrey Academy made it possible. The support I got was amazing, even though I was nervous at first as there was many courses to complete, they made it manageable,” she said.
Kevin, who left high school in Grade 11 to work and support his family, decided as an adult that he wanted to pursue a career in law enforcement. “When I started looking into applying to the police force, I realized that I needed my Ontario Secondary School Diploma before I could even begin the application process. I thought it was too late, but Aubrey Academy helped me figure it out. I could complete the courses online in the evenings, and I never felt judged or behind. It felt like I was finally getting the chance to start something I’d put on hold for too long.”
These stories are just two examples of what’s possible when adult learners are given the tools, support, and flexibility they need.
Your Diploma, Your Future
Earning your OSSD as an adult can unlock more than just post-secondary opportunities. It can lead to better job prospects, access to training programs, and the personal satisfaction of achieving a goal that once felt out of reach. Employers and colleges alike recognize the OSSD as a symbol of readiness and commitment.
The good news is: the path forward is clearer than ever. You don’t need to return to a traditional classroom or attend night school in person. With Aubrey Academy, your learning is customized to your schedule, your background, and your goals.
