Proposition 28 would require a minimum source of annual funding for K-12 public schools, including charter schools, to fund arts education programs. The annual minimum amount established by the law would be equal to, at minimum, 1% of the total state and local revenues that local education agencies received under Proposition 98 (1988) during the prior fiscal year. The minimum under the proposed law would be in addition to the funding required by Proposition 98. According to the Legislative Analyst's Office, the ballot initiative would likely result in increased spending of $800 million to $1 billion each fiscal year.
