Becoming a Trinity High School student is more than merely submitting an application. It is a process for you to come to know our school and to decide if Trinity offers the kind of experience that you and your family will want to be a part of. We love our school, and we want every Trinity family to feel as we do.

Students come to us from 45 different schools and 39 cities and towns. Some travel great distances to be here. Others make great financial sacrifices to afford a Trinity education. They obviously feel Trinity is worth such efforts. They are committed to providing their daughters and sons with a high school experience based on faith, scholarship, and character. We know our school is not for everyone. We know some students are not ready to commit to the high expectations for achievement that separates Trinity from many high schools. We want you to get to know our school better and make a deliberate choice to apply to Trinity.

How to Apply

The Trinity application process involves three steps: completing the application form PDF, having your current guidance counselor complete the recommendation form (freshman or transfer), and taking the admissions exam. Scheduling a tour or shadowing for a day is a great way to begin the process of getting to know Trinity. We ask that your application materials be returned to us by December 1st in order to allow time for a proper review before our February 1st acceptance date.
