The new money would be distributed according to what's known as an "evidence-based" model, which uses 27 metrics to determine an "adequacy target" — a dollar figure that each school district should spend per student in order to provide an adequate education. Schools that can't afford to reach their target would be first in line for the extra state money and entitled to the largest share. About 1 percent of the new dollars would be set aside for the state's wealthiest districts to share.
