Every spring, Connecticut taxpayers encounter the same school-budget ritual. School spending goes up. Officials cite fixed costs. When towns look for savings, the public conversation turns quickly to larger classes, fewer electives or staff reductions — while the contracts and work rules driving long-term costs receive far less scrutiny. The debate reliably focuses on the most painful cuts, while the structure producing them remains largely protected.
A new report from the Fordham Institute helps explain why.
A Crowded Table: Teacher Union Strength in 2026 ranks Connecticut 12th in the country overall, up from 17th in Fordham’s 2012 report. More strikingly, Connecticut now has the highest K–12 teacher-union membership rate in the nation, at nearly 98 percent. Nationally, the study finds teacher unions appear to be weakening. In Connecticut, they are deeply entrenched.
Connecticut ranks near the top in the categories that translate into real political power: 13th in resources and membership, 10th in political involvement, 10th in labor and bargaining policies. This is not simply a story about dues payments. It is a story about a politically organized institution with sustained influence over elections, collective bargaining and the rules that shape school spending.
Fordham’s most useful finding may also be its simplest: membership matters. Teacher-union membership rates, union voter share and union revenues are the strongest predictors of overall teacher-union strength. The percentage of teachers who belong to unions is the single strongest predictor of overall union power across states. Connecticut’s near-98 percent rate is not a footnote, it is the engine.
The mechanics follow from there. Near-universal membership creates durable organizational capacity. That capacity funds lobbying and campaign activity, which shapes political relationships. Those relationships help preserve the bargaining systems and labor rules that reinforce union leverage. Then the cycle repeats.
Nationally, that cycle has been disrupted. Teacher-union membership declined in 45 states and Washington, D.C. Union contributions to political parties fell in 34 states. Parent organizations, education reform groups and school-choice advocates have crowded what Fordham describes as a more contested policy landscape. Connecticut, along with much of the Northeast, has been largely insulated from that shift.
More than 56 percent of Connecticut public-school funding, roughly $7.9 billion, comes from local property taxes. State aid covers about 36 percent; federal funds account for roughly 8 percent. Local homeowners and businesses are therefore heavily exposed when education costs rise.
Fordham stops short of claiming unions cause higher spending. But it does find that stronger-union states tend to spend more per pupil and pay teachers more, even after adjusting for regional labor costs. In a state where local taxpayers already carry most of the burden, that correlation deserves more than a shrug.
Student outcomes are not a scandal. Connecticut performs respectably, and above the national average in several measures. But solid outcomes are not an argument against accountability. A state that combines high spending, heavy property-tax reliance and one of the strongest union environments in the country should be able to ask honestly whether the system is performing as well as it could, and that question rarely survives budget season intact.
Connecticut prohibits teacher strikes but substitutes binding arbitration, which can reduce local leverage over contract outcomes. The elected officials who approve town budgets often have less influence over compensation decisions than arbitrators who are never accountable to voters for the resulting tax increases.
This is the part that gets lost when education debates collapse into shorthand about being “pro-teacher” or “anti-teacher.” No serious argument holds that teachers should be underpaid or disrespected. The argument is about structure: who controls decisions, who bears costs and who is insulated from accountability when spending rises faster than taxpayers can absorb.
The path forward does not require hostility toward teachers. It requires more leverage for the people paying the bills. Start with transparency: contracts, side agreements and long-term cost projections should be published in plain language before approval. Arbitration should give greater weight to municipal capacity to pay, enrollment trends and property-tax pressure. And elected officials and school leaders, not collective bargaining, should control more operational decisions, so that accountability runs to voters rather than away from them.
None of those changes demonizes teachers. All of them modestly rebalance who holds power over decisions that cost taxpayers billions each year.
That Connecticut climbed from 17th to 12th in Fordham’s rankings while most of the country moved in the opposite direction is not an accident. The system is not failing the people it was built to protect. It is working exactly as designed, just not for everyone writing the check.
