Twelve of Ontario's 15 highest-ranking secondary schools and nine of Ontario's fastest-improving secondary schools are in the Greater Toronto Area, according to the Fraser Institute's annual rankings.
St. Michael's Choir (Sr) of Toronto and Bayview High School of Richmond Hill topped the list at one and two, respectively.
The report, rating more than 700 public, Catholic and francophone secondary schools, rank academic performance based on provincewide literacy and mathematics tests administered by the Education Quality and Accountability Office.
The worst-ranking school in the GTA was Sir Robert L. Borden, which ranked 710 out of 718.
Of the 20 fastest-improving secondary schools in the province, nine are in Toronto. Monarch Park ranked number one in that category, followed by Sir Sandford Fleming Academy.
Six schools in the GTA also resided in the bottom 15 of the list.
In general, public high schools in Toronto did not do very well, with Toronto schools scoring 5.3 points out of 10 — below the provincial average of six.
Although more than 26.6 per cent of secondary school exams written in 2011 scored below the provincial standard, the report shows this is an improvement compared to 30.1 per cent in 2007.
The report, which shows whether schools have improved or not over time, includes information about the makeup of each school, including demographics such as the parents' average income, percentage of students with English as a second language, and the percentage of special needs students.
