WIS offers financial aid based on need. Grants based on financial need are awarded to students whose families cannot afford tuition; about 14–15 percent of current students receive some financial aid, and aid is available to approximately 15 newly admitted students each year. Financial aid applications are processed through School and Student Services (SSS). Step One: Complete the Parent Financial Statement due January 15; Step Two: Submit supporting documentation due February 1 for new applicants and March 1 for returning; Step Three: Submit 2025 tax documentation due April 20. Newly admitted students receive grant notifications with offers in late February; returning students receive grant notifications mid-March to mid-April. The school intends to offer aid to every accepted student who demonstrates need, but funding may be limited; therefore families should apply for aid in parallel with their WIS application. See the Financial Aid brochure and guide for details.
