Tuition and Financial Aid at St. John XXIII College Preparatory (SJ23)

St. John XXIII College Preparatory (SJ23) is a private, coed Catholic high school in Katy, Texas, serving grades 9–12, and it maintains a dedicated Tuition & Financial Aid section under Admissions. That page is the authoritative source for current tuition figures and aid application instructions — the school does not publish specific dollar amounts in the general site content available here, so families should treat the Tuition & Financial Aid page as the starting point rather than relying on secondhand numbers.

What the school does confirm

The site's "At A Glance" section gives one concrete financial data point:

The $11M+ figure refers to scholarships awarded to the graduating class — typically merit and institutional awards from colleges and universities, not a statement of SJ23's own tuition or aid budget. It signals that graduates receive significant outside scholarship support, but it does not tell you what a family pays to attend SJ23.

Where to find tuition and aid details

The Admissions menu contains the relevant pages:

• Tuition & Financial Aid — the primary page for cost and aid information
• How to Apply — the admissions process, which typically runs alongside aid applications
• Important Dates — deadlines that matter for both admission and aid
• International Student Program — separate considerations for international applicants

Because pricing signals are not published on the pages captured here, the practical step is to open the Tuition & Financial Aid page directly and, if figures are gated or require a login, contact the admissions office for the current schedule.

What to check when you get there

When reviewing the Tuition & Financial Aid page, look for these specific items:

1. Tuition schedule — whether it is listed per year, and whether it differs by grade level.
2. Additional fees — registration, technology, retreats, athletics, fine arts, or graduation fees that sit outside base tuition.
3. Aid types — need-based grants, merit scholarships, or payment plans, and whether they are described separately.
4. Application requirements — forms, tax documentation, and whether a third-party service is used.
5. Deadlines — aid deadlines often precede or match admission deadlines, so confirm both.
6. International students — whether aid is available to international applicants or whether a different fee structure applies.

A realistic way to plan

Treat the published tuition as the base and budget for fees and incidental costs on top. If aid is a factor, apply early and in parallel with admission rather than waiting for an acceptance letter — many schools tie aid decisions to the admission timeline. If the Tuition & Financial Aid page does not state amounts, that is a signal to call or email admissions rather than assume a figure.

For a school with a 100% college acceptance rate and a stated mission of academic excellence, virtue, and service, the cost question is best answered by the school's own current materials — the Tuition & Financial Aid page and the admissions office — since tuition changes year to year and this site does not publish the numbers in its general content.
