The school funding law, signed Sunday, changes the way the state allocates money to public schools.
Under the law, aid is partly tied to the number of low-income students in each district. Suburban districts with enrollment increases and a large number of low-income students could see annual aid increases as big as 20 percent.
But most of 31 poor urban districts would see aid increases of 2 percent this year, then see state support held flat after that.
Advocates for urban districts are expected to ask the state Supreme Court to overturn the law.
