A Senate panel agreed Monday to the basic approach of the House school funding plan but tweaked its specific dollar amounts.

The House plan would add $122 million to Missouri’s $3.1 billion in basic aid for school districts. But it would authorize an increase of up to $278 million if revenues meet Gov. Jay Nixon’s more optimistic projections.

The Senate Appropriations Committee decided to provide a minimum $115 million increase, leaving a larger portion of the potential $278 million increase dependent upon improved revenue collections.

Senators typically change the House budget plan. Negotiators from the two chambers must work out their differences by early May.
