Calgary families choosing a secondary school are navigating four distinct systems at once: public, Catholic, charter, and independent (private). Each has different admission processes, different academic approaches, and different costs. The Fraser Institute publishes an annual ranking that compares all of them on the same scale — which is useful, but it answers a narrower question than most parents think. This guide covers Calgary secondary schools: how the landscape works, what the rankings actually measure, and how to figure out whether a highly ranked school is genuinely the right fit for your child.
The four types of secondary schools in Calgary
Public schools (Calgary Board of Education)
The Calgary Board of Education (CBE) operates the largest network of secondary schools in the city, serving students across all quadrants. Public schools are free, non-denominational, and follow the Alberta Program of Studies. Most offer a range of programming including Advanced Placement (AP), International Baccalaureate (IB) at select schools, and various specialized academic tracks.
Catholic schools (Calgary Catholic School District)
The Calgary Catholic School District (CCSD) operates a parallel, publicly funded system with a faith-based foundation. Catholic schools follow the same Alberta curriculum as public schools but integrate Catholic values and religious education. They are free to attend for students within the district.
Charter schools
Charter schools in Calgary are independently operated but publicly funded, meaning they are free to attend while offering a distinct pedagogical focus. Calgary has several well-established charter schools, each built around a specific approach — some focus on classical education, others on gifted programming, and others on STEM-intensive curricula. Charter schools generally have application processes and limited enrolment, so early research matters.
Independent (private) schools
Independent schools in Calgary are privately funded through tuition and typically offer smaller class sizes, specialized programming, and in some cases entrance requirements or assessments. Tuition varies significantly depending on the school’s focus and reputation, generally ranging from several thousand to over $20,000 per year for day students.
Some of Calgary’s independent schools use standardized testing as part of admissions, and the SSAT (Secondary School Admission Test) is one of the most widely accepted across Canadian independent schools generally. Even where a specific Calgary school does not require it, families applying to multiple independent schools — in Calgary or elsewhere in Canada — often find the SSAT comes up as part of a broader application strategy. For a full breakdown of the test and how to prepare, see our SSAT guide for Canadian parents.
| School type | Funding | Religious affiliation | Admission |
|---|---|---|---|
| Public (CBE) | Public | None | Catchment-based, open enrolment for specialty programs |
| Catholic (CCSD) | Public | Catholic | Catchment-based, open to families across faiths in practice |
| Charter | Public | Varies (most secular) | Application-based, often with waitlists |
| Independent/private | Tuition | Varies | Application, sometimes entrance assessment |
How Calgary secondary schools are ranked
The most widely cited ranking is the Fraser Institute’s annual Report Card on Alberta’s High Schools. The 2025 edition ranks 292 public, Catholic, independent, and charter secondary schools across the province using eight academic indicators generated from Grade 12 provincewide testing, grade-to-grade transition and graduation rates.
This is the most comprehensive single source comparing Calgary secondary schools across all four systems on a common scale. A few things are worth understanding about how to use it.
What the ranking actually measures
The Fraser Institute’s indicators are built from standardized academic outcomes — exam results, how reliably students progress from one grade to the next, and graduation rates. It is a measure of average outcomes for the student population at that school, not a measure of teaching quality in isolation, and not a prediction of how any individual student will do.
The 2025 edition also notes that contrary to common misconceptions, the data suggests every school can improve regardless of type, location, and student characteristics — meaning the ranking reflects current performance, not a fixed ceiling for what a school (or a student within it) can achieve.
A ranking does not predict fit
One striking example from the 2025 rankings: Webber Academy, a private school in Calgary, and Old Scona, an Edmonton public school, both scored a perfect 10 out of 10. A perfect score from a private, tuition-funded independent school and a perfect score from a free public school sit on exactly the same scale — because the ranking measures outcomes, not the type of school producing them.
This matters for Calgary parents specifically: a highly ranked school is not automatically the right choice for your child, and a school with a more modest ranking is not automatically the wrong one. The ranking tells you about the school’s historical average. It says nothing about whether your child is ready for that school’s pace, whether they’d thrive in a large school or a small one, or whether their specific academic gaps would be addressed there.
Calgary secondary schools by area
Calgary’s secondary schools are spread across the city’s quadrants, with concentration patterns that often track new community development.
Northwest Calgary has a strong concentration of established public and Catholic high schools, alongside several charter school campuses.
Southeast Calgary has seen significant growth in newer communities, with Catholic schools historically posting strong Fraser Institute results in this quadrant.
Northeast Calgary includes a mix of public and Catholic schools serving some of the city’s most diverse communities.
Southwest Calgary includes several of the city’s most established independent schools alongside public and Catholic options.
For families house-hunting with school catchments in mind, it is worth confirming current catchment boundaries directly with CBE or CCSD, since boundaries are periodically redrawn as Calgary’s population grows.
Charter schools in Calgary: what makes them different
Charter schools deserve particular attention because they occupy a unique position: free like public schools, but with a distinct academic identity like an independent school.
Calgary’s charter schools each have a defined pedagogical focus — examples include schools built around explicit, structured academic instruction, schools focused on gifted and high-ability programming, and schools with a STEM-intensive curriculum. Because they are publicly funded but capped in enrolment, most have an application process and many maintain waitlists, particularly for popular grade-entry points.
If a charter school’s specific academic approach matches how your child learns best, it can offer some of the benefits associated with independent schools — smaller class sizes, a defined academic culture — without tuition costs. The trade-off is uncertainty around enrolment and the need to apply well in advance.
What actually matters when choosing a secondary school in Calgary
Beyond the ranking, the following factors are worth weighing for any Calgary family choosing between public, Catholic, charter, and independent options:
Academic pace and rigour. Some schools — across all four systems — offer AP or IB programming for students who want a more demanding academic track. Whether your child is ready for that pace, or would benefit more from a standard track with room to build confidence, matters more than the school’s overall ranking.
Class size and individual attention. Independent and charter schools generally offer smaller class sizes than large public high schools. For a student who needs more individual attention to stay on pace, this can matter more than a school’s headline reputation.
Transition readiness. A school’s grade-to-grade transition rate (one of the Fraser Institute’s core indicators) reflects how well, on average, students at that school progress without falling behind. A student entering with solid foundational skills is statistically more likely to keep pace at any school; a student with existing gaps benefits from knowing exactly what those gaps are before the transition, regardless of which school they attend.
Application requirements. Charter and independent schools often require an application, and some independent schools use an entrance assessment. Knowing where your child’s academic skills currently stand — not just their report card grades, which can vary in rigour between schools — gives you a much clearer picture of how they’re likely to perform on an entrance assessment.
How Think Academy Canada supports Calgary families
Think Academy Canada works with high-performing students across Canada from Grade 1 through Grade 12, fully online — which means Calgary families have access to the same instructors and programmes as families anywhere else in the country.
For Calgary parents weighing secondary school options — whether that’s preparing for a charter school’s entrance process, strengthening academic foundations before a competitive independent school application, or simply understanding where a child stands before a major transition — our approach starts with a diagnostic.
Every new student completes a free assessment and receives a personalised feedback report showing exactly where their academic skills sit. This gives you something a province-wide ranking cannot: a clear, individual picture of your own child’s readiness, rather than an average drawn from an entire school’s student population.
FAQ
What are the types of secondary schools in Calgary?
Calgary has four types of secondary schools: public schools (Calgary Board of Education), Catholic schools (Calgary Catholic School District), charter schools (publicly funded but independently operated with a specific academic focus), and independent schools (privately funded through tuition).
How are Calgary secondary schools ranked?
The most widely used ranking is the Fraser Institute’s annual Report Card on Alberta’s High Schools, which compares public, Catholic, charter, and independent schools using academic indicators from provincewide testing, grade transition rates, and graduation rates.
Do private schools rank higher than public schools in Calgary?
Not necessarily. The Fraser Institute’s rankings include schools of all types, and top scores appear across public, Catholic, charter, and independent schools. A school’s funding model does not determine its ranking — academic outcomes do.
What is a charter school in Calgary?
A charter school is publicly funded and free to attend, like a public school, but operates independently with a specific pedagogical focus — such as classical education, gifted programming, or STEM-intensive curriculum. Charter schools typically require an application and have limited enrolment.
How much does private secondary school cost in Calgary?
Tuition at Calgary’s independent secondary schools varies significantly, generally ranging from several thousand dollars to over $20,000 per year depending on the school. Contact individual schools for current tuition figures, as these change annually.
Should I choose a secondary school in Calgary based on its Fraser Institute ranking alone?
No. The ranking reflects average academic outcomes for a school’s student population over time. It does not predict how an individual student will perform, and does not account for fit factors like class size, teaching style, or whether a school’s pace matches a specific student’s current academic level.
How do I know if my child is ready for a more academically rigorous school in Calgary?
The clearest way is a diagnostic assessment that shows exactly where a student’s current skills stand relative to grade-level expectations, rather than relying on report card grades alone, which can vary in rigour between schools and grading systems.
What is the difference between Calgary’s public and Catholic school systems?
Both the Calgary Board of Education (public) and Calgary Catholic School District are publicly funded and free to attend, following the same Alberta curriculum. The Catholic system integrates Catholic values and religious education; the public system does not have a religious affiliation.
Do charter schools in Calgary have entrance requirements?
Many charter schools have an application process, and some — particularly those focused on gifted programming — may include an assessment component. Requirements vary by school, so checking directly with each school’s admissions process is recommended.
How can Think Academy Canada help Calgary families choosing a secondary school?
Think Academy Canada offers a free diagnostic assessment for students in Grades 1 to 12 anywhere in Canada, including Calgary. The assessment identifies exactly where a student’s academic skills stand, giving families a clear, individual basis for choosing between school options — rather than relying on rankings or report cards alone.
