Knox County Teachers' DB Plan
Transparent derived index from public pension-plan filings, not an official rating. A 4-dimension composite (funded ratio, contribution discipline, 5-year investment return, unfunded burden), each scored against this dataset's own percentile distribution across 197 reporting plans. Not the same as the plan's headline funded-ratio grade above. See the exact dimensions, weights, and formula.

How this score is calculated (benchmark table)
| Dimension | P10 | P25 | P50 | P75 | P90 | Weight |
|---|---|---|---|---|---|---|
| Funded ratio (higher = better) | 57.6% | 67.2% | 75.0% | 87.0% | 97.6% | 0.35 |
| Contribution discipline (ARC) (higher = better) | 88.4% | 100.0% | 100.0% | 104.1% | 122.1% | 0.25 |
| 5yr investment return (higher = better) | 6.4% | 7.5% | 8.3% | 9.1% | 9.9% | 0.20 |
| Unfunded burden (lower = better) | 2.0% | 12.7% | 25.0% | 33.1% | 42.4% | 0.20 |
Percentiles computed across all 197 plans in this database with a reported value for that metric (2026-09-09). A dimension a plan does not report drops out of its composite, and that weight redistributes across the dimensions it does report, so thin reporting never silently lowers a score relative to a fully-reported peer.

Funded ratio, 2001 to 2024
Assets as a share of the benefits already promised, one point per reported year. Down 25.7 points across the series. This is the multi-year table's series, so its last point can be a later year than the plan card above, which reports the plan's own latest valuation.
What changed, FY2023 to FY2024
6.2 pts funded ratioKnox County Teachers' DB Plan's funded ratio fell 6.2 points from FY2023 to FY2024, with assets contributing -3.2 points and the accrued liability contributing -3.0.

Where the 6.2-point move came from
- Assets
- -3.2 pts
- Accrued liability
- -3.0 pts
Accrued liability is the source-reported value for benefits already promised. The two contributions are the move the ratio would have made on the prior year’s liability (assets) and the remainder (liability); they sum to the total by construction. Both years shown provide source-reconciled actuarial assets and liability, so neither figure rests on a ratio published on its own.

Where this data comes from + how funding gaps get resolved
These figures come from the Public Plans Database, a collaboration between the Boston College Center for Retirement Research and NASRA that compiles them from each plan's Comprehensive Annual Financial Reports (CAFRs) and actuarial valuations. The relationship between contribution adequacy and investment performance determines whether an unfunded liability narrows or expands year over year, and the gap itself is typically closed through some combination of higher contributions, investment returns, or benefit modifications. See our methodology for how public-pension funding differs from ERISA-backed private plans, and our disclaimer below before acting on this data.
