As costs to educate students with disabilities have risen and state and federal special-education funding has remained steady, the share of local funds used to pay for special-education services in California has increased to 39% from 32%, between 2005 and 2011, according to a report from the state Legislative Analyst's Office. The report predicts growth in the amount of funds needed to serve this student population, as there has been a 240% increase in diagnoses of students with autism and a 120% rise in the number of students with low-incidence disabilities that require costly services.
