What is left to pay after the state award
PCTC pays up to $5,000 per student. Up to $7,500 for a student with a qualifying disability. It follows the tax year, so 2026 expenses are claimed in early 2027.
| Grades | Median published tuition | Award | Left to pay at the median |
|---|---|---|---|
| Kindergarten to grade 5 | $7,930 | Up to $5,000 | $2,930 |
| Grades 6 to 8 | $8,250 | Up to $5,000 | $3,250 |
| Grades 9 to 12 | $10,720 | Up to $5,000 | $5,720 |
"Left to pay" is the median price minus the award, for a student who gets the award. It leaves out fees, books, uniforms and any aid the school gives. "Up to" means the award can be lower. A tax credit comes back through the family's state tax return, so the family pays the school first.

Compared with public school spending
Idaho's public schools spent $11,060 per student in fiscal year 2024 (U.S. Census Bureau). The median published private tuition above ($8,375) is 76% of that figure.
- Public spending is not a price. It is total current spending on public schools (teachers, staff, upkeep, transport, meals and more) divided by enrolled students. No family pays it, and it leaves out building construction and debt.
- The years differ. Public spending is for the 2023-24 school year, the latest the Census Bureau has published; tuition is mostly for 2026-27. Neither is adjusted for inflation.

Read this before you quote it
- This is not a random sample. We started with the largest schools and the schools families already search for, so large, established schools are over-represented. Treat the medians as "what these schools publish", not as the average for every private school in Idaho.
- These are published prices before financial aid. Required fees, books, uniforms and transport are extra, and many schools lower the price through aid.
- Many schools do not publish a price, and those are missing here. School years: 12 for 2026-27.
- Each figure was read on the school's own website or tuition sheet, and a script re-opened that page and kept the figure only if the same dollar amount appears on it. Most recent check: .
