Top 10 Private High Schools in Kansas City
Direct Answer
The Best Overall private high school in the Kansas City metro is Pembroke Hill School in Kansas City, Missouri, an independent college-prep school whose 100% college matriculation, deep AP and honors catalog, and small classes make it the metro's clearest academic leader.
The Best Value pick is St. Thomas Aquinas High School in Overland Park, Kansas, a Catholic school that delivers strong college outcomes, broad activities, and a faith-based community at tuition well below the independent schools. This list is built for families and students weighing where to enroll across the Kansas City metro, spanning both the Kansas and Missouri sides, with a focus on academics, college outcomes, and fit.
Every pick uses real, publicly reported data from school profiles, Niche, the National Association of Independent Schools, and diocesan sources.
How We Ranked the Top 10
We weighted each school against the priorities families tell admissions offices and survey firms they actually care about, drawing on published figures from Niche, U.S. News, school profiles, the National Association of Independent Schools (NAIS), and the College Board. The weighting:
- Academic performance (test scores, AP/IB) - 25%
- College and post-grad outcomes - 20%
- Value and cost - 15%
- Teachers and resources - 15%
- Environment and safety - 15%
- Extracurriculars and fit - 10%
A school that posts elite test scores but graduates few students, or wins on reputation but offers thin programs, drops fast. The winners balance all six.

Which One's Right for You?
What to Look For When Choosing a Private High School
- College matriculation and outcomes - A school that sends nearly all graduates to four-year colleges, with a strong share at selective universities, signals consistent academic strength.
- Tuition and financial aid - Independent schools like Pembroke Hill cost roughly double the Catholic schools; check published aid budgets before ruling a school out.
- AP/honors depth and class size - Look at how many rigorous courses are offered and how small classes actually are, which reflects real attention per student.
- Mission and environment - Catholic, Christian, independent, single-sex, and coed schools offer very different cultures; match the mission to your family.
- Signature programs - A Jesuit service tradition at Rockhurst or a global program at Barstow may serve a specific student far better than a higher overall ranking.
- Athletics and activities - Larger schools like St. Thomas Aquinas offer deeper sports and activities than the smallest independents.
What matters less than marketing implies: a school's reputation alone, its newest building, or a single ranking number. Fit, program access, affordability, and a supportive teacher relationship affect a student's outcome far more than a headline figure.
