New York City Public Schools' Computer Science for All (CS4All) initiative set out to ensure that every student receives at least one meaningful, high-quality computer science (CS) experience within each grade band (K-2, 3-5, 6-8, and 9-12). As described in previous work, the percentage of schools offering some form of CS tripled from 15 percent before the initiative to 45 percent in the 2022-2023 school year. This report examines short- and longer-term student outcomes associated with CS course-taking, including CS attitudes, computational thinking (CT) skills, academic achievement, continued CS engagement, and postsecondary pathways. Several recommendations for policy and practice are also outlined. Overall, the CS4All initiative made substantial progress in expanding CS opportunities across New York City schools. Promisingly, CS course taking was associated with a number of positive student outcomes, including improved CS confidence, CT skills, and (for high school students) a greater likelihood of pursuing CS in college. Yet, disparities in CS participation and outcomes persist. Continued investments in culturally responsive practices, well-aligned pathways and assessments, and expanded course availability will be crucial to advancing CS4All's vision of high-quality computer science for all students.
