In 2002 the government of Mike Harris introduced a controversial program to partially fund all private schools, but this was criticized for undermining the public education system and the program was eliminated after the Liberals won the 2003 provincial election. In other provinces, privately operated religious schools are funded. In British Columbia the government pays independent schools that meet rigorous provincial standards up to 50% of the per-student operating cost of public schools. The province has a number of Sikh, Hindu, Christian, and Islamic schools. Alberta also has a network of charter schools, which are fully funded schools offering distinct approaches to education within the public school system. Alberta charter schools are not private and the province does not grant charters to religious schools. These schools have to follow the provincial curriculum and meet all standards but are given considerable freedom in other areas. In all other provinces, private religious schools receive some funding, but not as much as the public system. As the education system in Canada is managed by the varying provincial governments in Canada, the way the educational stages are grouped and named may differ from each region, or even between districts and individual schools. The ages are the age of the students when they end the school year in June. English schools in Quebec have the same grade system as French schools, but with English names. For example, "elementary school" is not called "école primaire" in an English school, but has the same grading system. The following table shows how grades are organized in various provinces. Often, there will be exceptions within each province, both with terminology for groups, and which grades apply to each group. Notes:
