 During the 2010–2011 academic year, 73 per cent of students in Grade 12 managed to complete their secondary studies in four years, with over 20,000 Grade 12 students, or 14 per cent of Ontario's Grade 12 student population returning for a "victory lap," in the following year.In September 2013, the Government of Ontario introduced a 34-credit threshold (30 credits is necessary to receive the Ontario Secondary School Diploma), in an effort to limit the length of study for its secondary school students.The Government of Ontario estimates the credit cap would save the province C$22 million each year.
