Special Education Category Multiples

Six multiples, 0.2435 to 3.9554, one per disability category — a sixteen-fold range that is most of what special education funding is. The only FSFP parameter the Revised Code states with no end date, and the only one enacted by an act other than the current budget.

Six numbers, written out in R.C. 3317.013 in the same order as the categories they price: 0.2435, 0.6179, 1.4845, 1.9812, 2.6830, 3.9554. Each multiplies the statewide average base cost per pupil, the district’s ADM in that category, and its state share percentage. verified the section, in crates/project/fixtures/revised-code.txt

The range is the policy. A Category 6 pupil generates sixteen times what a Category 1 pupil does, so which category a child is assigned to is not an administrative detail — it is most of the money. Statewide, Category 6 is 15% of the pupils and 48% of the aid; Category 2 is 65% of the pupils and 34%. verified crates/project

What they multiply is not obvious from the numbers. The multiplicand is the general statewide average base cost per pupil, $8,241.61, and not the career-technical figure 20% above it that career-technical multiples use. Two schedules, two multiplicands, and no published table says so; a reader comparing a special education weight against a career-technical one as though they sat on one scale is out by a fifth before any pupil is counted. verified

This is the one that does not expire Contents

Of the nine Revised Code sections that carry the Fair School Funding Plan’s parameters, this is the only one stated flatly. Three — R.C. 3317.011, 3317.017 and 3317.0217 — open with “This section shall apply only for fiscal years 2026 and 2027”. Five more hand their values back clause by clause: forty divisions across six sections read “For fiscal year 2028 and each fiscal year thereafter, an amount calculated in a manner determined by the general assembly”. R.C. 3317.013 does neither. verified counted over the committed extract

It is also the only one of the nine not amended by the current budget act. Its effective date is 6 April 2023 and its source is H.B. 554 of the 134th General Assembly; every other section here carries H.B. 96 of the 136th and 30 September 2025. verified the extract’s own date: and source: fields

Whether the durability is deliberate or an artifact of the section not having needed amendment is not established, and the two are not distinguishable from the text. open

The six ratios are the General Assembly’s of 2001, carried and never repriced Contents

Every one of the plan’s six is 0.8379 times the corresponding weight in the Evidence-Based Model of 2009 — the same constant on all six, agreeing to a part in eight thousand. The plan did not re-derive this schedule; it rescaled it. In dollars that is a rise of 11.1% on the FY2017 amounts, identical for every category, which is what a single scalar means and a different act from repricing. verified crates/project

Those 2009 weights are in turn the FY2002 schedule with one change: category two roughly doubled, from 0.3691 to 0.7374, and the other five moved by less than 3 per cent. So the ratios Ohio prices disability with in FY2027 are the ratios the 124th General Assembly set, carried through four regimes and re-expressed twice. verified

And for eight years the schedule was dollars, not multiples Contents

FY2014 through FY2021 each category carried a per-pupil amount instead of a weight: $1,503 to $24,407 in FY2014, rising 2 per cent a year to FY2017 and then frozen — H.B. 49 holds them at the FY2017 figures and the Bridge formula computed no categoricals at all. Those amounts are the 2009 weights times a single per-pupil figure, $5,171 in FY2014 and $5,431 in FY2017, so even the regime that paid in dollars was paying the same six ratios. verified

That is why “the multiples before FY2022” had no answer in the form it was asked: for eight years there were none. The ratios, which is what the question was after, never went away.

What moved was which children are in which category Contents

H.B. 1 reassigned vision-impaired and orthopedically disabled pupils to categories with a higher weight, and LSC records it in a sentence rather than a number: in FY2002 category three read “hearing impaired, vision impaired, severe behavior handicapped” and category four “orthopedically handicapped, other health – major”; by FY2010 vision impaired had moved into category four, where it still is. No weight in any of the four schedules records that, and for a child it is the larger change of the two. verified

And the range has never been priced Contents

Naming the categories settles what is being ordered; it does not say what any of it costs. No source this corpus holds prices a category, so whether a sixteen-fold funding range tracks a sixteen-fold difference in the cost of educating a child is unanswered. open

The history above narrows where an answer could be. Four regimes have applied these six ratios and none of them derived them: 2009 rescaled 2001 by category, 2013 converted them to dollars, 2021 converted them back to weights. Whatever costing sits under the schedule, if one does, is older than every source in this corpus. inference

KindLegislated, and the only one of the plan's schedules that stays legislated past FY2027.

R.C. 3317.013 states the six multiples as a bare list with no fiscal-year condition attached to any of them, so nothing has to happen for them to hold and an act has to pass for them to move. That is what the taxonomy's legislated means, and it is the ordinary case a reader would assume for all of these. It is in fact the exception — see findings.

All six verified against the Revised Code to the last digit, not only against the department's calculator — crates/project/tests/the_statute_behind_the_weights.rs. That distinction is the point of the check: every earlier verification confirmed the department agreed with itself, and a spreadsheet can be internally perfect and still not be the law. verified

Unchanged across FY2026 and FY2027, the two years this corpus holds. The section has been in force in this form since 6 April 2023. verified
Statutory basisR.C. 3317.013, read. The categories are defined by cross-reference to Chapter 3323 rather than in this section; the multiples are here. The preschool halving of the same six multiples is R.C. 3317.0213 and is a separate parameter — preschool special education amounts. verified
Simulation keyproject::panel::categoricals::SPECIAL_EDUCATION_WEIGHTS.

A constant, not a lever. Policy exposes four fields — the guarantee rule, a base cost scale, the minimum state share and two phase-in percentages — and none of them is this. A counterfactual that moved a category weight cannot currently be run.
Written in formulas as
  • the school-age weights
SensitivityMoves $722m, the second-largest categorical, and moves it unevenly. Because the caseload is concentrated in Category 2 and the money in Category 6, a proportional change to all six weights and a change to Category 6 alone have very different distributional shapes: the first follows the pupils, the second follows the money. inference

The multiplicand matters as much as the multiple. Every one of these is priced in the statewide average base cost per pupil, so Base Cost Per Pupil moves all six at once — which is why the scenario runner's base_cost_scale carries about $812m of categorical exposure on top of what base cost alone does. verified crates/project

A program dominated by a category that is a sixth of its caseload is sensitive to identification practice in a way a per-pupil program is not. A small change in how many children are placed in Category 6 moves more money than a large change in Category 2. inference

What this node does not hold Contents

what set the 0.8379 rescaling — The committed analyses establish that the plan multiplied the 2009 schedule by one constant; none of them says why that constant. The Fair School Funding Plan workgroup's own materials, which this corpus does not hold, are where a rationale would be.

the schedule before FY2002 — The earliest committed LSC analysis is the 124th General Assembly's, and it states the six as already settled rather than as new. Whether the 124th set them or inherited them is a question for the analyses of the 123rd and earlier, which the extract does not reach.

what a category costs — No source this corpus holds prices a disability category. A costing study, or the department's own build-up if one exists, is what would settle whether the range tracks cost.
