The people in front of the classroom
Teacher experience shapes everything else in a school. These maps track how the experience of Missouri’s teaching workforce has shifted by district since 1991. For salaries, see the Teacher Pay page; for every view at once, the full explorer.
What this page shows
- The median Missouri teacher earns 7.5% less in real terms than the median teacher did in 1991. Adjusted for inflation, pay has gone backwards.
- 45.7% of teachers in the median district hold a master’s degree, and its teachers average 12.6 years of experience.
- Experience is not spread evenly across the state. These maps show where the workforce has aged, where it has turned over, and where it has thinned.
Experience change from any starting year
Choose a baseline year and the map recalculates how the average experience of each district’s teachers changed by 2025. It opens on 2024 to make the latest one-year shift easy to see; move the baseline farther back for a longer view.

Where teachers hold a master’s degree
The share of each district’s teachers holding a master’s degree or higher. This is partly about who a district can attract — and partly about what it can afford, since nearly every Missouri salary schedule pays more for an advanced degree. The statewide median district sits at 45.9%.
What workforce capacity does — and does not — predict
Districts with higher teacher salaries, more advanced-degree teachers and more experienced teachers tended to have higher achievement levels in a matched 2009–2019 comparison. They did not tend to have faster learning rates. That distinction is a useful finding, not a verdict on whether teachers or money matter.

Experience follows the paycheck
The two maps on this page look like they are about years of service and degrees earned. Underneath, they are about the same thing every other page on this site keeps finding: what a district can afford to pay is what a district can attract and keep.
Your child’s teacher’s years of experience and letters after their name are not a measure of how much your school district values good teaching — they are, to a real degree, a measure of what your district can afford to offer. The median suburban district’s staff averages 14.3 years of experience and 69% hold an advanced degree; the median rural district sits at 12.4 years and 42%.
At the extremes it is stark: Clayton reaches 97% of teachers holding a master’s degree, while a handful of small rural districts report none at all. That gap is not a verdict on how much those communities’ teachers care — it is what a thinner tax base can buy.
Certification deserves the same care as salary and experience, but the counting unit matters. A report may describe teachers, courses or assignments, and those are not interchangeable. This site is holding the district comparison until DESE provides the assignment-level Screen 20 file and its denominator rather than turning a grouped statewide summary into a district claim it cannot support.
The Pick Your Baseline tool above is worth running against your own district’s recent history, not just 1991: slide it back five or ten years and you will see whether your staff has gotten more veteran or greener lately — and whether that lines up with a round of retirements, a pay change, or a nearby district hiring your teachers away.
These maps are downstream of the funding maps elsewhere on this site. Nearly every Missouri salary schedule pays more for a master’s degree, so a district’s ability to attract and retain advanced-degree teachers is, in practice, a test of its tax base. The 55-point gap between Clayton’s 97% and the districts reporting none at all is a property-wealth gap wearing a credentials costume.
The steepest experience shortfall by community type sits in cities (11.9 years, the lowest of any group) — a reminder that this is not simply a rural-versus-everyone-else story. Urban districts carry their own distinct staffing pressure.
If you want to know what your school taxes buy, teacher experience and credentials are as real a return as a new building — they just don’t show up on a bond issue. A veteran, credentialed staff is retained, not conjured; districts compete for it the same way they compete for anything else that costs money.
By community type: rural districts hold their staff to 12.4 years despite 6.8% less real pay since 1991; suburban districts reach 14.3 years against a steeper 10.9% real-pay decline. Experience is not simply about who pays the most today — it is about who pays enough, for long enough, to keep people.
- How does our district’s teacher experience compare to the statewide median of 12.6 years — and to districts of our own type (rural, town, suburban, or city)? The by-community-type table above has the numbers.
- What share of our teachers hold a master’s degree, against the statewide median of 45.9%?
- Has our staff gotten more veteran or greener in just the last five years? Move the baseline tool back five or ten years and see what recent hiring and retirements have actually done.
- When district assignment data become available, what share of our courses are taught outside the teacher’s certification area — and is that concentrated in particular subjects or schools? Until then, ask what a statewide figure actually counts before using it to judge a district.
- If our advanced-degree share is low, is that about who applies — or about what our salary schedule can offer once they do? Read this page next to the Teacher Pay page before deciding.
