Why Families Choose O’Connell
Competence. Conscience. Compassion.
O’Connell College Preparatory School seeks to develop competence, conscience and compassion in our students through a challenging program of spiritual, academic, social, and extra-curricular activities.
We are a family
Students here are known personally, not counted. Smaller classes mean teachers notice when something clicks — and when it doesn’t.
Faith at the center
Campus Ministry, theology, School Mass, morning prayer and community service are part of ordinary life here, not an add‑on.
Real college preparation
Honors and AP coursework, dual‑credit classes that earn college credit in high school, hands‑on college counseling, SAT/ACT prep and scholarship guidance.
Room for every student
Here a student can be an athlete, an artist, a leader and a scholar in the same year. At O’Connell Prep, nobody has to pick one identity.
Leadership and service
Student Council, National Honor Society, Campus Ministry leadership, and community service are woven into the student experience.
Galveston roots, Buccaneer pride
Generations of island families, a strong alumni community, and traditions like the Treasure Ball that connect today’s students to the ones who came before.
What Students Can Do Here
Every program, open to every grade
Academics, arts, athletics and ministry are offered across the entire high school — so students can start exploring in ninth grade and keep going.

Questions Parents Ask
Good questions, straight answers
Do we have to be Catholic to enroll?
No. O’Connell is a Catholic school and faith is part of daily life here — theology class, Mass, service — and families of every background are welcome and part of our community.
Can my student earn college credit in high school?
Yes. Dual credit and college credit opportunities, AP Mathematics and advanced or honors coursework are available, along with college counseling, SAT and ACT resources, and help with applications and scholarships.
Is tuition assistance available?
Yes. Families may qualify for Texas Education Freedom Accounts (TEFA), Guardian Angel Scholarships or ACE Scholarships, and we help with college scholarship assistance later on. Ask us and we will walk you through the options.
We live on the mainland. Is the commute realistic?
It is. Student transportation from the mainland to Galveston Island is available, and a number of our families make the trip every day.
Can my student try a day before we decide?
Absolutely. Shadow Days let prospective students spend a school day with us — classes, teachers, lunch, the whole thing. Request information and we will set one up.
