The Admissions Interview

The admissions interview is a vital part of our admissions process. It provides an opportunity for our admissions and administrative teams to meet prospective students and their families, learn more about them personally, and begin forming meaningful connections. This first conversation marks the beginning of the strong partnerships we value between students, families, and our school community.

Student Acceptance:

This is the exciting moment our prospective students have been waiting for—our official acceptance letter. It represents the culmination of each student’s hard work and dedication to character, faith, and scholarship. Acceptance letters are issued on a rolling basis throughout the application process, allowing families to receive timely decisions without lengthy wait periods. New students are admitted on a conditional basis, with the expectation of continued academic growth and positive behavior both at their current school and upon arrival at Trinity.

Enrollment: 

Beginning in early January, accepted students and their families will receive the Trinity Enrollment Packet to finalize the enrollment process. Accepted families will receive a direct notification when the Enrollment Packet is available.

Accepting Enrollment: 

As part of accepting enrollment, families are required to submit a non-refundable enrollment fee of $125, which increases to $250 after January 31.

Families will work with our Tuition Manager, Mrs. Garand, to review tuition agreements, payment plan options, and financial aid eligibility. Mrs. Garand will also guide families through the grants and scholarships available to Trinity families.

Catholic education is often more affordable than many families expect. Enrollment is secured once the tuition agreement is signed and a payment plan is established.
