Which One's Right for You?
What to Look For When Choosing a Private High School
- College matriculation and graduation rates, A school that sends most graduates to four-year colleges signals consistent outcomes, not just selective admission.
- Tuition and financial aid, Compare sticker tuition against each school's aid budget; the elite independents often discount heavily for qualifying families.
- AP/honors depth and class size, Look at how many advanced courses are offered and the student-faculty ratio, which shape real classroom rigor and attention.
- Mission fit, Catholic, Christian, and nonsectarian schools differ sharply in culture; choose one whose values match your family.
- Specialized programs, A learning-differences focus at Denver Academy or an all-girls model at St. Mary's may serve a specific student far better than a higher overall ranking.
- Environment and support, Visit to gauge community, counseling, and student support rather than relying on reputation alone.
What matters less than marketing implies: a single ranking number, the newest building, or sticker tuition alone. Fit, real aid, and program access shape a student's outcome far more than a headline figure.
