According to Cardus, Quebec has the highest proportion of students going to private high schools in North America (17%). Most of these are Catholic. The Quebec government subsidizes the schools on a per student basis, so that a student's tuition is about one-third of the cost. About half of the total sample of 500 Quebec students survey identified themselves as coming from a Catholic independent school. The number of graduates of independent non-religious schools was too small to draw any conclusions. What the Cardus study was therefore able to do is compare the Quebec graduates who attended fully funded government schools with those who attended partially funded Catholic independent schools.
