How HSPT registration usually works
Registration runs through the high schools themselves, not the diocese: families typically register for the exam at their first-choice school, and many schools share scores with the other schools a student applies to (confirm each school’s policy). The exam is taken once, usually between late November and January — see the full application timeline, and start with a free 25-question practice testto find your student’s baseline.
