Please note that a complete business day is usually the minimum time required to schedule your testing date. Seating is given on a first come first serve basis. We recommend ordering at least a week ahead. You will receive an e-mail confirming the testing start date and time. Testing will normally take 2 consecutive days for the Stanford. The Olsat is usually done at the start of the last day of testing for High School (9-12) students and the next day for the lower grades. Estimated time is 3 hours per day for the Stanford and 1 hour for the OLSAT. Testing is available year round.
