Access to important educational resources in California's middle and high schools is not equal among schools that serve different student populations. Overall, the most disadvantaged populations of middle and high school students are likely to have the least access to the resources necessary for learning. California policymakers are focusing on how resources are allocated and used in the public school system. Information on the current distribution of resources among schools throughout the state would aid their review and decisionmaking. This report provides a detailed and up-to-date snapshot of the distribution of some of the most critical resources in California's middle and high schools--classroom teachers, class sizes, and college-going courses. It examines how these resources are distributed across schools grouped into quartiles by the percentage of low-income students, English language learners, Hispanic students, and African American students; by the population density of the areas in which schools are located; and by the type of school (traditional public or charter), to determine whether different measures of teacher qualifications show the same unequal distributions across schools serving students with varying educational needs.
