This article describes the results of a California state law established in 2010 that created "Districts of Choice." The District of Choice law was meant to encourage districts to compete for students by offering innovative programs and this-school-fits-my-child options that parents wanted. This designation meant that children from any other school district could transfer to a District of Choice school without first getting approval--or even seeking it--from their home districts. The law opened a new era of entrepreneurship in education in which schools improve their programs in order to retain and attract students. The author reports on the effect this new law had on the creation and operation of the Riverside Unified School District, located east of the Los Angeles area. The unified district launched a science and technology middle school, a dual-language immersion elementary school, an all-digital high school, an arts-centered grade school, a virtual school starting at grade 3, and more. Kronholz comments on other effects this new law has created for surrounding district superintendents, parents, and students.
