Tuition & Aid

Saint Mary’s Catholic High School bases its tuition policy on the premise that tuition payments are an investment in your child’s education and Christian formation. It is the duty of the school administration, in the spirit of Christian stewardship, to ensure that adequate financial resources are available for the school and that enrollment is as affordable as possible to all families.

Financial Aid - Tuition Assistance Opportunities

We want to be sure that tuition is affordable for all students who want to attend St. Mary’s. We work with Student Tuition Organizations (STOs), Foundations, private donors and other organizations to provide tuition assistance to all who request assistance. Student’s eligibility for tuition assistance is determined by household size and household income and needs to be documented by 2023 tax returns. Completing all applications recommended by due dates result in the maximum assistance.

Financial Aid assistance will be available in the Business Office. Contact Michelle Hernandez at mhernandez@smknights.org, Veronica Acosta at vacosta@smknights.org (bilingual) or Briana Valdez bvaldez@smknights.org (bilingual) to schedule an appointment.

Scholarship Information List

Merit Scholarship

Saint Mary’s Catholic High School is proud to award incoming freshmen the Saint Mary’s Merit Scholarship. Students are selected for this distinct honor based on multiple factors from their high school applications, including but not limited to, their HSPT scores, grades, teacher recommendations, online application, and student-parent interviews.  Upon a critical review of all of these items, Saint Mary’s selects a limited number of students whom we believe will continue to excel academically and greatly benefit from a Saint Mary’s education. The scholarship applies all four years.
