The chamber also signed off legislation that would require school boards to spend at least 70% of their operating expenditures on “direct classroom expenditures.” 

The amendment cleared the Senate along a similar party line vote last week with all Republicans in favor and all Dems opposed. It now goes to voters for a statewide referendum April 1.

The amendment, approved 17-15 with Republican Rob Stafsholt absent today, next heads to the Assembly, which plans to take it up Tuesday.
