Tuition Assistance
We are committed to building a community of learners, and that means making a Principia education affordable for all qualified students preschool–grade 12.
Tuition assistance is based on demonstrated need and comes in the form of grants, not loans. Applications are completed online via the School & Student Services (SSS) website. There is a $55 application fee. Tuition assistance applications follow the same admission application deadlines. Admittance and tuition assistance decisions are communicated at the same time.
