Independent Schools of St. Louis

Secondary School Standard Application Online

Eleven ISSL Secondary Schools participate in the ISSL Secondary School Standard Application Online. Applying online is the easiest and most convenient manner to apply to one or more of these participating ISSL schools.  By applying online using the ISSL Secondary School Standard Application Online (SAO), families can apply to multiple schools simultaneously, enter demographic information and responses to questions only once, submit application fees electronically, have a digital record of their application, and register for the SSAT Admission Test. The online application also gives parents and students the opportunity to review and make changes to the application before its submission.  All information is electronically saved and delivered to schools via a secure portal.
