Charter schools and school districts have been at odds since the first charter school law passed in 1991. Districts resent the competition and subsequent funding loss for traditional schools. Charters resent the lack of access to facilities and other resources and attempts to infringe on their autonomy. Yet a fast-growing number of school districts and charters are working together to resolve challenges and reduce costs. In this article, Robin J. Lake explores the innovation, transparency, and equity that district and charter leaders are using to collaborate to make it easier--and more equitable--for families to navigate an array of public school choices. Lake describes efforts in the works under the topics: Making Collaboration Work; How State Boards Can Help; and Collaboration Helps State Boards. Lake says that the bottom line is that state boards of education can lead on school improvement and equity by leading on support for district-charter collaboration. States that leave matters to chance risk leaving many students and their families behind, and they squander opportunities to meet the goals they set.
