What if Indiana used
Iowa’s classification method?

An enrollment-based look at competitive equity: account for free and reduced-price lunch eligibility, then compare two ways to place schools into six classes.

Iowa method · Smaller 6A and 1A · The class sizes, movement lists and school alignment below reflect the selected projection.

Independent scenario · Prepared October 12, 2026 · Not an official IHSAA proposal

01 / The method

Enrollment, adjusted for FRL eligibility

Adjusted enrollment =
Grades 9–11 enrollment × (1 − 0.40 × FRL rate)

For a school with 1,000 students in grades 9–11 and a 37% FRL rate, the adjusted enrollment is 852. Schools are ranked by this number from largest to smallest, without a success-factor adjustment.

Two choices for class balance

The Iowa formula supplies the adjustment. Class sizes are a separate choice. This projection places 30 schools each in 6A and 1A, and 64 each in 2A–5A. Changes reflect both adjusted enrollment and class sizes.

“Current class” means the official class in the supplied Indiana classification document, including success factor. This analysis uses its full 316-school field, not just the tournament draw. Actual official class counts can differ from the projection’s target sizes.

Data assumptions and missing FRL information

Public and charter schools use their corporation’s 2025–26 FRL rate as a proxy. Matched private schools use the IDOE FY2026 school nutrition report. Corporation-wide rates and NSLP/CEP eligibility are imperfect substitutes for school-specific income-based FRL data.

Culver Academies, Park Tudor and Evansville Reitz Memorial have no matched FRL entry. Their grades 9–11 enrollments are left unadjusted. This is a missing-data assumption, not a finding that their FRL rate is zero; different rates could change their placement and the cutoffs for other schools.

Assignments use unrounded adjusted enrollment; ties are ordered alphabetically. Displayed values are rounded to two decimals.

02 / Enrollment distribution

Most schools sit toward the smaller end

The curves trace the actual, skewed distribution rather than a symmetrical bell curve. Each dot represents one school. Both graphs use the same scale, but the current graph counts grades 9–12 while the Iowa graph adjusts grades 9–11. The Iowa graph depicts the original smaller-6A-and-1A projection; the school tables and movement lists reflect your selected projection.
