Wentzville R-IV School District
Lake St. Louis’ K–12 school district, shared with Wentzville, Foristell, Flint Hill, Dardenne Prairie. It’s its own government, with a budget separate from the town’s.
Of the $13,482 per pupil, $7,757 goes to the classroom (teachers, aides, supplies); the rest to buses, buildings, counselors and administration. Building projects and debt payments aren’t in the per-pupil figure.

No comparison or trend for Lake St. Louis yet
The fair comparison uses 2022, the last year the Census Bureau counted every government (later years are a sample), and Lake St. Louis’ 2022 figures are a Census estimate (it reported none of its 2022 dollars). It reported 2023 only (2022 and 2024 are estimates), so there is no trend yet either. The next full count is 2027.
