In general, depending on the school, an entrance exam or other testing may be required. Grades from previous years may also be considered but are not the overall factor in acceptance. Each school varies on their specifications, so it's a good idea to ask the individual school regarding ICES evaluation and credits. We have some additional information on the admissions process here: http://www.ourkids.net/school/applying-to-schools.php. In this case the best advice would be to contact the schools you’re most interested in to inquire about this specific criteria.
