Financial aid is available for students in kindergarten through eighth grade. Grants are made on the basis of demonstrated need within the limits of the School’s financial aid budget. Aid is granted for one year only. A new application must be submitted each year.

St. Mark's Episcopal School has chosen to use the FAST system by Independent School Management (ISM) to process financial aid applications. ISM provides standardized and impartial processing using a confidential, secure web site.

The financial aid process is overseen by the Financial Aid Committee, which includes the Rector, Head of School, Chair of the School Advisory Board and the Business Manager.
