Tallgrass is committed to making the school accessible to as many families as possible, regardless of ability to pay. Here’s one parent’s take on the value of a Sudbury education for her son.

Tallgrass tuition for 2026-2027 is a sliding scale depending on income, ranging from $2,335 to $13,600 for the year. We offer sibling discounts of at least 30% per sibling, with the details determined on a case by case basis.

*After October 1, 2026, all mid-year enrollees pay the prorated amount of the full tuition. Below is our standard tiered system for a full school year.

FINANCIAL AID INFORMATION
Tallgrass Sudbury School is committed to maintaining and supporting an economically diverse student body. We are proud to offer one of the lowest tuitions and most generous financial assistance packages among any Sudbury school in the country. 

Tallgrass determines Financial Aid based on the aggregate Adjusted Gross Income of all parents/guardians of a student and, therefore, requires financial information from all parties.
