The SLI The Sidney Ledson School 220 Duncan Mill campus (near the intersection of DVP and 401) is an ideal exam-proctorship setting for students that are best able to demonstrate their academic abilities in a smaller group (no more than 18 students) or that require developmental-condition-based testing accommodations on Flex dates.  To find out if there is an available sitting scheduled at the SLI  campus, you must first create an account and register for an exam by visiting ssat.org.  To request scheduling in a private or semi-private administration setting on closed Flex dates, please email sidneyledsonschool@gmail.com.
