The 2006 California Educational Opportunity Report provides new analyses of data about how well California's K-12 public schools are preparing students for college, and it compares California's schools with schools across the nation. For the first time, policymakers and parents can look across the state and see, for every high school, the relationships among California's educational infrastructure, rates of high school completion, and enrollment in the state's four-year colleges and universities. This statewide analysis finds that California students face significant roadblocks on their pathway to college. These roadblocks help explain why California sends fewer students to four-year colleges than most other states in the country.
