The California Roundtable (CRT) played a critical role in the shaping and passage of California's Senate Bill 813 (SB 813), the State's major education reform legislation enacted in July 1983. This working paper analyzes the content of the legislation, assesses its likely impact on student performance, and recommends steps the CRT (a consortium of business executives) might take to support improved student preparation in California. It is predicted that the new law will have a measurable effect on performance. And although student preparation for college and work may thus improve somewhat, additional legislative and non-legislative steps, the report holds, must be taken to bring the State's students up to an acceptable level. If the Roundtable chooses to remain active in helping to improve student performance, it should--according to this assessment--support legislation that: funds SB 813's reforms for 1984-85 and beyond; establishes essential personnel reforms omitted from SB 813; and strengthens measures that are included in SB 813 in incomplete or weakened form. Moreover, the Roundtable should actively seek long term solutions to the problem of providing adequate and stable financing for the public schools. Finally, in the non-legislative area, the Roundtable is encouraged to support the current plans of the Joint Business-Education Task Force on Mathematics and Science Education, and the establishment of a network of effective business/community/education programs. Extensive appendices to this report include (A) Reform provisions of SB 813; (B) Comparison of CRT legislative agenda with SB 813; and (C) the authors' recommendations for a new teacher certification process and a new principal selection and evaluation process.
