CS4All Hack League

The CS4All Team is excited to partner with BetaNYC to launch the 2018-19 CS4All Hack League. Through hackathons, middle and high school students are encouraged to apply CS concepts and practices to solve real-world challenges. In the past, New York City students have worked together to prototype, create, and demo apps, games, and business plans. This year, up to 100 middle and high schools from across the City are invited to participate in a friendly competition in which student teams will be given the opportunity to use open data, including 311 data, from their school neighborhoods to address issues impacting their own communities. Students will use this data to engage in a human-centered design and strategic problem-solving process aimed at improving quality of life and civic issues in their neighborhoods.

The Hack League will kick off with in-school, teacher-led hackathons during CSEdWeek (December 3-9, 2018). Student teams will then progress to borough-wide hackathons in the winter of 2019. The final, citywide hackathon will take place in the spring of 2019.

NYC public middle and high school teachers with prior CS experience can sign up here!

Here are recaps and pictures from our past hackathons.

Hack Packs are here!

In addition to Hack League curriculum, schools can host their own hackathon with the CS4All Hack Packs! Each Hack Pack contains a teacher guide, student worksheets, day-of slideshow, and scoring rubric. All files are editable.
