Six ways to size the reserve run from $90,554 to $412,397; the law caps it at $541,717.
| Value | |
|---|---|
| The most the law allows | $541,717 |
| Worst year, at today’s budget | $412,397 |
| Worst two years running | $368,596 |
| Worst year | $223,774 |
| Median bad year, at today’s budget | $121,615 |
| Median bad year, last five | $116,811 |
| Median bad year, all 17 | $90,554 |
Overruns beyond the three special education lines’ budget, FY2010 to FY2026. At today’s budget is our arithmetic.

A mark: that year’s overrun, as spent, fit inside the reserve, assuming it was full when the year began.
What it means: Every option meets the small years; they differ only on the biggest few, and the 3 largest meet every year on record.

Each year’s overrun as a share of its own budget, times $6,209,427. Older years grow most, because the budget was smaller then.

2 · What it shows
- 1
A median bad year ran $90,554 over; scaled to today’s budget, $121,615; in the last five years, $116,811.
What it means: The three medians differ mostly by how old years are counted; recent years and scaled years agree more closely.
- 2
The worst year was $223,774 as spent; FY2013 ran 6.6% over, which is $412,397 at today’s budget.
What it means: Whether old overruns count at today’s size nearly doubles the worst case; nothing in the data settles it.
- 3
At today’s budget the worst two years running come to $643,417, past the $541,717 cap.
What it means: If overruns grow with the budget, no reserve the law allows covers a repeat of the worst stretch.

Covered means the year’s overrun, beyond the three lines’ budget as first voted, fit inside the reserve, assuming the reserve was full at the start of the year. At today’s budget, each year’s overrun as a share of its own budget times $6,209,427, the three lines in FY2026: our arithmetic, which assumes overruns grow with the budget.
