Public Schools Accountability Act (PSAA) of 1999
This act is intented to provide for the academic development of students in California's schools.  By June 30, 2002 it will provide a full evaluation disaggregated by categories including English language learners.

Academic Performance Index (API) - This is the cornerstone of the PSAA.  The purpose is to measure the performance of schools in terms of student achievement and assign a single index in order to compare schools and measure growth.  Results from English learners will be included in the school’s API but data for this subgroup will not be disaggregated until Fall 2001. Although other indicators will be added as they become available, for the first 2 years the API will be based on the SAT-9 test, which may not be a valid instrument for evaluating English learners.

Includes several resources addressing the needs of English language learners, mostly PowerPoint presentations.  However one report of interest is Designing a Standards-Based Accountability System for Language Minority and Immigrant Student Populations.
