An investment in a St. Thomas Aquinas High School education will yield positive dividends for years to come.

We remain faithful to maintaining an outstanding educational program while keeping the St. Thomas Aquinas experience as affordable as possible. Providing the best education possible requires a highly qualified faculty and staff, diverse academic and co-curricular programs and a strong adherence to our mission. It is important to note that one in three families receive financial assistance from St. Thomas Aquinas High School.

We are committed to being the best stewards of every dollar we receive. Determined annually, tuition represents a portion of the total cost to educate each student. With no financial support from the Diocese, the remaining piece comes from our annual Aquinas Fund campaign. We are grateful to the many donors who help keep tuition affordable through their generous gifts to the school.  

What sets St. Thomas Aquinas High School apart from other schools is its sense of community or, in essence, its sense of family. As family, your son or daughter will be cherished, guided, respected and transformed.

And that's an investment not just for school, but for life.



2023-2024 Tuition: $17,926

Fees: $400


Tuition Assistance

St. Thomas Aquinas High School recognizes the challenge for parents in providing a quality education for their children. We understand the difficulty and sacrifice necessary to meet the financial weight of tuition. It is our endeavor to keep tuition as low as possible while operating the school in a fiscally responsible fashion. St. Thomas Aquinas allocates a portion of its annual budget to provide St. Thomas Aquinas Grant Aid for qualifying families.

Although STA tuition is set much lower than its private school counterparts, we are able to offer the highest quality education that lands our graduates into top colleges. Additionally, last year our graduating class (the Class of 2022) earned a total of $4,397,469 in merit awards/scholarships and financial aid.  STA-Graduation-2022-168.jpg

All families are eligible to apply. A demonstrated financial need is the first criteria. Financial need is determined by FACTS Grant and Aid Assessment and reported to the school following an application to FACTS. The Financial Aid/Tuition Assistance Committee will make an evaluation and award aid by matching the ability to pay tuition with resources available. 

There are many opportunities for financial assistance, for scholarships, and even opportunities to host an international student, which many families find is enough to bridge the gap between a tight budget and affordability.  If you are interested in applying for financial aid, please reach out to our Financial Aid Coordinator, Mrs. Lisa Puffer, as your very first step in the process.  Mrs. Puffer will walk you through the steps and carefully explain the process so that it will be as smooth a journey as possible.  You may call her at 603-609-1423 or email her at

Payment Options

St. Thomas Aquinas families have four options for paying tuition: Single Payment, Semi-Annual Payment, 10-Month Payment Plan, and a 12-month Payment Plan. For information about each, please contact our Chief Financial Officer, Lisa Durken, at
