Jane Wells on the WordPress development blog announced WordPress has been accepted into the Google Code-In 2010. There were only 20 open sourced organizations accepted for the contest.
The Google Code-in is described on the WordPress Codex as follows:
Google Code-in is a Google program similar to Summer of Code, but aimed at pre-university students. The code-in is different from GSoC in that it operates as a task-based contest rather longer pre-determined mentorships, and includes more than just code projects, to help expose students to “the many kinds of contributions that make open source software development possible.”
