AccessCSforall: making computer science accessible to K-12 students in the United States

For the past ten years there has been a concerted effort to bring computer science to K-12 students in the United States (US) and in other countries. There is a growing realization that computer science is a fundamental subject like mathematics and sciences. In order to make this effort include the approximately 7.4 million K-12 students with disabilities in the US we created AccessCSforAll, a National Science Foundation project that began in 2014. In this article we review the activities of AccessCSforAll in the professional development of teachers and in tool and curriculum development.
