Visit, Apply, & Key Dates

Key Dates, One Click

Applying to high school comes with a lot to keep track of, and the important dates do not always fall neatly in the same month. We do not want a missed deadline or a buried email to stand between your son and St. Thomas.

This page brings the full admissions calendar together in one place. Add the dates that matter to your family, and each reminder will include the registration, application, or RSVP link.

No digging through old emails. No wondering what comes next. Just helpful reminders when your family needs them.
