Five years after Proposition 13 took away money from California schools, Senate Bill 813 brought it back—but with strings attached. The bill, hailed as the largest educational reform measure in California's history, was passed in 1983. Its provisions were backed by a major financial commitment—more than $3.2 billion over three years to public schools, designed in part to compensate for the financial losses caused by Proposition 13. A second report on the results of SB 813, made by a PACE research project, was released in July. The report, "Curricular Change in California Comprehensive High Schools Between 1982 and 1985," found an increase in the number of academic courses being offered in public schools, and in the number of students taking them. Between 1982–83 and 1984–85, the report found, math and science course offerings and enrollments have increased by about 20 percent. In the same period, the report found, foreign language enrollment rose 12 percent and advanced placement courses—which can lead to college credits for high school students—rose 117 percent.
