Charter School Students Outperform Public School Students

New research from think tank SecondStreet.org shows that, across 22 provincial tests, charter school students in Alberta earned higher scores than their peers attending government-run public schools.
The Provincial Achievement Tests results [PATs] examined in the report covered English, mathematics, science, and social studies for Grade 6 and 9 students. On average, charter school students’ scores were 9.3 percentage points higher than government-run public schools and 7.7 percentage points higher than government-run Catholic (separate) schools based on PATs written between 2022-24.
“It’s interesting that charter schools are funded by the government, run by non-profits and yet their test scores were so much higher,” said SecondStreet.org Research Director Bacchus Barua. “Ask any parent if they want their child to go to a school where students tend to score nearly ten points higher on average and the answer is obvious. The provincial government will want to think about how it can help more kids access these high-performing schools.”
Some highlights from the research include:
- SecondStreet.org examined provincial test score data for over 1,400 government-run public schools, government-run Catholic schools and charter schools in the province between 2022-24. For the last 22 provincial tests where comparisons could be made, charter school students earned higher grades on average in every subject compared to their peers in government run-schools.
- Looking strictly at results from 2024 (the most recent year available), students at Alberta’s charter schools achieved, on average, test results that were 9.5 percentage points higher than students at government-run traditional public schools and 8.1 percentage points higher than government-run Catholic schools across six subjects (not including Grade 6 English and Mathematics, which were not administered).
- The largest difference in performance was for Grade 9 Mathematics in 2024 – 14.1 percentage points higher in charter schools compared to government-run public schools, whereas the smallest was for Grade 6 Science in the same year – 6.2 percentage points higher in charter schools compared to government-run Catholic schools.
“It’s interesting that when you talk with charter school staff they’ll tell you that, like government-run public schools, their students also come from all walks of life – lower income families, higher income, those from new Canadian homes, students that were born here and everything in between,” added Colin Craig, President of SecondStreet.org. “Maybe the government could facilitate some sessions for charter schools to share advice with government schools.”
