Voter-approved initiatives that amended the California Constitution in 1988 and 1990 to guarantee a minimum amount of funding from property and state taxes for K-14 (kindergarten through community college) education each year. This guarantee of a minimum funding level is unique in the nation. The propositions included formulas for calculating the guarantee under different economic conditions. Proposition 98 also mandated School Accountability Report Cards (SARC) that cover at least 13 required topics such as test scores, dropout rates, and teacher qualifications. (Other topics have since been added.)
