Choosing a high school in Calgary means weighing dozens of options across public, Catholic, and private systems—each with different programs, cultures, and costs. The decision shapes not just academics but your child's entire high school experience, from friendships to future opportunities.
This guide breaks down Calgary's top-performing schools, explains how rankings work, and walks you through finding the right fit beyond the numbers.
Calgary high school rankings at-a-glance
Calgary's top high schools include Western Canada High School, Sir Winston Churchill High School, and Dr. E.P. Scarlett High School from the public system, alongside private options like Webber Academy and Strathcona-Tweedsmuir School. All of them score well on provincial diploma exams and offer specialized programs like International Baccalaureate (IB) and Advanced Placement (AP)—both are university-prep programs that go beyond regular high school courses.
Rankings give you a starting point when you're comparing schools. They don't tell the whole story, though, because they can't measure things like school culture or how supported your child might feel.

Average Fraser score table
The Fraser Institute rates schools on a 10-point scale based on provincial exam results. Here's where Calgary's top schools land:
The scores shift a bit each year as student performance changes.
How these Calgary rankings are calculated
The Fraser Institute publishes the most widely used rankings in Alberta. They look at several factors to create an overall picture of how well a school prepares students for what comes next.
Knowing what goes into the numbers helps you see what they reveal and what they miss.
Fraser Institute indicators
The Fraser Institute evaluates schools based on Grade 12 diploma exam results, which count for 30% of a student's final grade in core subjects. Schools get points for the percentage of students who write exams, average scores across all subjects, and how many students fail or excel.
The system also tracks whether schools are improving or declining over time. A school that's moving up in rankings might be worth a closer look, even if it's not at the very top yet.
Diploma exam averages
Alberta students write standardized provincial exams in subjects like English, math, biology, chemistry, physics, and social studies, which count for 30% of a student's final grade in core subjects.
Schools with higher average scores typically have strong teaching and engaged students. A school with slightly lower averages might offer other strengths—like exceptional arts programs or inclusive learning environments—that don't show up in the numbers when achieving high academic performance.
University entrance rates
Many top Calgary high schools track how many graduates get accepted into post-secondary programs. Schools with strong university entrance rates often have dedicated counselors who help students navigate applications and scholarships.
This metric matters if your goal is university. Not every student takes that path, though, and some excellent schools also support students heading into trades or apprenticeships.
Top public high schools in Calgary Alberta Canada
Calgary Board of Education schools offer tuition-free education with access to specialized programs that rival many private institutions, serving 142,403 students as of 2025-26. The schools draw students from designated catchment areas, though some accept out-of-boundary applications when space permits.
Public schools in Calgary have earned recognition for academic excellence and innovative programming.
Western Canada High School
Western Canada High School sits in the Killarney neighborhood near downtown and has offered the International Baccalaureate program since 1980. The IB diploma program challenges students with university-level coursework across six subject areas, plus extended essays and community service requirements.
Beyond academics, Western has championship-level music programs and competitive athletics. The school's diverse student body reflects Calgary's multicultural character.
Sir Winston Churchill High School
Churchill, in northwest Calgary, consistently ranks among the city's top performers for both IB and Advanced Placement programs. Students can choose between the two pathways depending on their learning style and university goals.
The school maintains a diploma completion rate above 90%. Churchill's large campus includes modern science labs, a performing arts center, and extensive athletic facilities.
Ernest Manning High School
Ernest Manning serves communities in Calgary's southwest, including Signal Hill and West Springs. The school stands out for innovative electives like broadcasting, yoga, and entrepreneurship alongside traditional academic subjects.
Manning's teachers integrate technology throughout the curriculum. Students describe feeling known by their teachers despite the school's size.
William Aberhart High School
Aberhart offers Calgary's largest French Immersion high school program, drawing students from across the city who've been in immersion since elementary school. The school also runs English-stream courses and offers both IB and honors classes.
Students at Aberhart consistently perform well in sciences and mathematics. The school's clubs and sports teams create tight-knit communities within the larger student population.
Top Catholic high schools in Calgary
Calgary Catholic School District schools combine faith-based values with academic rigor. The schools welcome students from Catholic families and others who want a values-centered education.
Catholic schools in Calgary often emphasize community service and character development alongside traditional academics.
St. Francis High School
St. Francis, located in northwest Calgary, serves one of the city's largest Catholic high school populations. The school balances strong academic results with active athletics programs and student leadership opportunities.
Students participate in regular faith formation activities and service projects that connect classroom learning to real-world impact. Graduates frequently mention the school's welcoming environment.
Bishop Carroll High School
Bishop Carroll uses a self-directed learning model where students work at their own pace through course material with teacher guidance. This approach works well for motivated learners who thrive with independence and flexibility.
The school's structure allows students to accelerate in subjects where they excel or take extra time where they struggle. Bishop Carroll consistently ranks as one of Calgary's top Catholic schools for university preparation.
All Saints High School
All Saints, a newer school in the deep south, features modern facilities and forward-thinking teaching approaches. The school's smaller size means students often develop close relationships with teachers and staff.
All Saints emphasizes technology integration and project-based learning alongside traditional instruction. Community involvement programs connect students with local organizations and service opportunities.
Top private high schools in Calgary
Private schools charge tuition but often provide smaller class sizes and specialized programs. Calgary's independent schools range from academically intensive to those focused on specific educational philosophies.
Tuition at Calgary private high schools typically ranges from $15,000 to $25,000 per year.
Webber Academy
Webber Academy, in Aspen Woods, maintains Calgary's highest Fraser Institute ranking year after year. The school's rigorous curriculum starts in junior kindergarten and builds through Grade 12.
Class sizes average 18 students, allowing for individualized attention. Webber students regularly win provincial and national awards in science fairs, debate competitions, and mathematics contests.
Strathcona-Tweedsmuir School
Strathcona-Tweedsmuir School sits on a rural campus south of Calgary, where outdoor education is woven into the curriculum. The school offers the complete IB continuum from elementary through high school.
Students spend significant time learning outside, whether on the school's trails, at the outdoor education center, or on extended wilderness trips. This approach develops both academic skills and personal resilience.
Calgary French and International School
Calgary French & International School provides full French immersion education from preschool through Grade 12. Located in Cougar Ridge, the school is a UNESCO Associated School and accredited IB World School.
Students graduate fluently bilingual in French and English, with many also studying Spanish. Families come from diverse backgrounds, creating an international community within Calgary.
Master's Academy and College
Master's Academy, located near Crowchild Trail, emphasizes classical education with a focus on humanities, sciences, and arts. The school's small class sizes and individualized approach help students develop critical thinking and communication skills.
The academy's curriculum includes daily character education and leadership development. Graduates often describe the school's close-knit community as a defining feature of their experience.
Special programs that set these schools apart
Beyond standard Alberta curriculum, Calgary's top schools offer specialized programs that challenge students and prepare them for specific post-secondary pathways. The programs often require applications, prerequisite grades, or entrance assessments.
Knowing your options helps you match your child's interests and abilities with the right school environment.
International Baccalaureate
The IB Diploma Programme is a two-year curriculum for Grades 11 and 12 that's recognized by over 4,500 universities worldwide. Students take six subjects at higher or standard levels, write an extended essay, complete community service hours, and study theory of knowledge—a philosophy-style course about how we learn and know things.
IB is more challenging than regular Alberta diploma courses. Universities often grant advanced credit or admission advantages to IB graduates. Calgary schools offering IB include Western Canada, Churchill, Aberhart, and Dr. E.P. Scarlett.
Advanced Placement
AP courses allow high school students to take college-level classes and earn university credits through end-of-year exams, with most U.S. colleges offering credit or advanced placement for qualifying scores. Unlike IB, which is a complete program, students can take individual AP courses in subjects that interest them.
AP works well for students who want to accelerate in specific areas without committing to a full alternative program. Many Calgary public schools offer AP options alongside regular courses.
STEM and robotics academies
Several Calgary schools have developed specialized science, technology, engineering, and math programs. The hands-on programs include robotics competitions, coding courses, and partnerships with local tech companies.
STEM programs prepare students for careers in engineering, computer science, and emerging technology fields. Schools with strong STEM offerings include Ernest Manning, Dr. E.P. Scarlett, and Sir Winston Churchill.
Arts-centered learning
Some Calgary high schools emphasize music, drama, and visual arts alongside academics. Western Canada High School's music program, for example, has produced award-winning bands and choirs for decades.
Arts programs develop creativity, collaboration, and discipline. Students serious about arts often choose schools where programs receive significant resources and attention.
Choosing the right school beyond the numbers
Rankings provide useful data, but they can't tell you whether a school will be the right fit for your family. The best school for your child depends on their learning style, interests, commute, and what matters most to you.
Taking time to look beyond the numbers helps you find a school where your child will thrive.
Campus culture and values
Every school has its own personality. Some are competitive and fast-paced, while others emphasize collaboration and community. Visiting schools during open houses gives you a sense of whether the environment matches your child's needs.
Pay attention to how students and teachers interact in hallways and classrooms. A school where students seem engaged and teachers appear approachable often indicates a positive culture.
Extracurricular depth
High school is about more than academics. It's where students discover interests, build friendships, and develop leadership skills that prepare them for the transition to university. Schools with robust clubs, sports teams, and volunteer programs create opportunities for well-rounded development.
Ask about participation rates in extracurriculars, not just what's offered. A long list of clubs doesn't matter if only a handful of students participate.
Commute and catchment zones
Calgary's size means some students travel significant distances to attend specific schools. Public schools have designated catchment areas, though families can apply for out-of-boundary transfers if space permits.
Consider how commute time affects your child's schedule, especially if they want to participate in after-school activities. A school closer to home might offer better work-life balance than a higher-ranked school across the city.
Cost and fees
Public and Catholic schools are tuition-free, though families pay for course materials, field trips, and optional activities. Private schools charge annual tuition ranging from $15,000 to $25,000, plus additional fees for technology, athletics, and trips.
Some families find private school tuition worthwhile for smaller classes and specialized programs. Others prefer investing resources in tutoring, enrichment activities, or saving for post-secondary education.
Step-by-step guide to using rankings in your decision
Rankings work best as one tool among many in your school selection process. Here's how to use them without letting numbers make the decision for you.
This approach balances objective data with your family's unique priorities.
1. Identify academic goals
Start by clarifying what you want from high school—strong preparation for university, specific program options like IB or French Immersion, or a supportive environment for students with learning differences. Your goals narrow the field considerably.
Students aiming for competitive university programs might prioritize schools with high diploma exam averages. Those interested in trades or creative fields might look for different strengths.
2. Short-list by program fit
Once you know your priorities, create a list of schools offering relevant programs within a reasonable commute. Check whether schools require applications, have entrance requirements, or accept out-of-boundary students.
This step eliminates schools that don't match your needs, even if they rank highly overall. A top-ranked school without your desired program won't serve you as well as a mid-ranked school with exactly what you need.
3. Visit open houses
Most Calgary high schools host open houses in fall and early spring where families can tour facilities, meet teachers, and ask questions. The visits reveal aspects of school life that rankings can't capture.
Bring your child along and pay attention to their reactions. Sometimes a school that looks perfect on paper doesn't feel right in person, or a less obvious choice surprises you positively.
4. Confirm boundary or application requirements
For public schools, verify whether you live within the catchment area or need to apply for an out-of-boundary transfer. Catholic schools require proof of Catholic baptism or a pastor's letter for priority admission.
Private schools have their own application timelines, often requiring applications by January or February for the following September. Missing deadlines can mean waiting another year.
How tutoring can boost admission and success
Getting into competitive programs or succeeding once you're there often requires additional academic support. Tutoring helps students strengthen prerequisite grades, prepare for entrance assessments, and keep up with rigorous coursework.
Many Calgary families use tutoring strategically at key transition points.
Strengthening Grade 9-10 prerequisite marks
Competitive high school programs often consider Grade 9 and 10 marks when accepting students into IB, AP, or specialized streams. Strong performance in the early years opens doors later.
A tutor who knows Alberta curriculum can help students build solid foundations in core subjects like math, science, and English. This preparation pays off when students apply for advanced programs or scholarships.
Entrance exam and interview prep
Some private schools and specialized programs require entrance exams or interviews as part of admission. The assessments test academic readiness and sometimes critical thinking or problem-solving skills.
Working with a tutor familiar with the processes helps students approach assessments confidently. Practice with exam formats and interview questions reduces anxiety and improves performance.
Ongoing subject support for IB or AP rigor
IB and AP courses move faster and go deeper than regular high school classes. Students sometimes struggle to keep up with the pace or grasp complex concepts before high-stakes exams.
Tutoring provides targeted support in specific subjects without requiring students to drop down to easier courses. Many students find that a few tutoring sessions before major exams make a significant difference in their final grades.
Find a tutor who knows Alberta curriculum and can support your child's specific academic goals.
