JEFFERSON CITY, Mo. — The Missouri Senate endorsed a budget plan Monday that ensures a funding increase for public education but will require negotiations with the House to hammer out the final specifics.

The plan provides a larger funding increase to public colleges and universities than the version approved by the House earlier this year, though it has a slightly smaller increase to public K-12 school districts. Those differences are among the many variations that will have to be resolved by House and Senate negotiators before a May 9 deadline to pass a final version of the 2015 budget.
