Some schools in Ontario offer a third method of FSL education: the Extended French program. Students enter into this program as early as Grade 4—the starting grade is set by each region's school board—and may continue the program through to graduation. The program can also be entered when beginning secondary school; however, as there is a prerequisite number of previous instruction hours, usually only students previously enrolled in the Extended French or French Immersion programs can enter. In this program, at least 25% of all instruction must be in French. From Grades 4 through 8, this means that at least one course per year other than "French as a Second Language" must be taught solely in French. From Grades 9 through 12, along with taking the Extended French language course every year, students must complete their mandatory Grade 9 Geography and Grade 10 Canadian History credits in French. Students who complete these required courses and take one extra credit taught in French receive a upon graduation in addition to their diploma.
