Thank you for your interest in Mater Dei School!

Mater Dei School provides an accelerated yet basic Catholic education in which character development is emphasized and appreciated as much as academic accomplishments. In a traditionally structured yet relaxed atmosphere, the students are encouraged to work and play hard; accordingly, a strong athletic program complements the scholastic curriculum.  

Below, please find general school and admissions information.



William G. McMurtrie

Head of School

Please check back in early September for the link to submit

an application for the 2025-2026 school year



9:30am to 11:30am

OCTOBER 22, 2025

Mater Dei follows an open application policy and practices a policy of nondiscrimination on the basis of race, color, and national origin with respect to the admission and treatment of students, faculty, and administrative staff.  Admissions decisions are based on standardized testing (administered by Mater Dei) in conjunction with records and recommendations provided by the applicant's current school.  

Please note that most new students are admitted to Mater Dei in the first, fifth and sixth grades and that openings in other grades depend upon current student attrition. Accordingly, if you apply for a grade other than first, fifth or sixth grade, the general admissions timeline occurs later should a spot become available. 


General admissions timeline for first, fifth and sixth grades:

  • Sept-Oct-Nov-Dec:  Complete online application by early December

  • Parent Interview/Tour:  Applicant parents will receive an application acknowledgement via email with instructions for scheduling an Admissions Interview

  • December/January:  First grade applicants take readiness tests in small groups

  • Late December:  Recommendation forms and transcript requests are sent to the applicants’ current schools from Mater Dei

  • Saturday, January 11, 2025:  Fifth and sixth grade admissions testing

  • Financial Aid:  Financial Aid applications for families new to Mater Dei must be completed by January 15, 2025. (Due date for current families is December 15, 2024)

  • Late February:  Mater Dei mails acceptance letters to applicants’ homes
