Our goal is to make sure all K-12 students have access to computer science in their schools. New York City and Chicago Public Schools -- two of the largest districts in the country -- have announced that computer science will be in all schools, and in Chicago, it is a required graduation credit. And in the past two years more than 21 states have responded to this growing interest by passing policies to boost computer science. Let's work together and make it a reality in all schools.
