We are migrating to a new website for Computer Science Principles. DNS changes will be complete by September so that csprinciples.org will map to that site, but you can see the new site now here: apcsprinciples.org --- it will include the information from this site and more, but in a more modern web-friendly site.
The Computer Science Principles Development Committee has announced that the Investigate/Data Performance tasks will be dropped. There will be only two performance tasks going forward with Computer Science Principles. New versions of the other performance tasks, Create/Programming and Explore/Impact, will likely be available soon.
