GPL Challenge 2022

Our 2022 virtual Girls Programming League Challenge will be on Sunday, September 25, 2022. This year the theme of our contest will be CS & Medicine!

The GPL Challenge is a one-day event comprising a programming contest, keynote speech, panel discussion, and awards, with the goal to inspire and empower young women to participate in computer science, technology, and AI. The competition will provide female students with the opportunity to solve creative programming problems in either a novice or advanced division, while the keynote speech and panel discussion aim to give the participants insight into the current state of the field from a female perspective.

Our Program

CS/Programming Classes

We provide free programming classes (Java, Python, etc) and classes on AI at local libraries. We also guide students to work on hands-on activities.

Annual Programming Contest

The GPL challenge is an annual event that seeks to bring girls from different communities together to share their passion for programming. It includes a programming contest, a set of workshops, a keynote speech, and a panel discussion with women in STEM and computer science.

The 2022 Challenge, with the theme Medicine & CS, will be held on September 25!

Our Impact

Through teaching middle and high school students programming and STEM classes, we motivate them to learn and keep challenging themselves.
