According to HootSuite the gist of the program is
In one sentence, the program helps empower students to connect with each other, become leaders in the social media space at their school and community, as well as be the voice of HootSuite on campus. This program will give students a unique opportunity to build your own campus community and gain recognition by effectively using social media. By becoming a HootSuite Campus Ambassador, you will join an exclusive network of students from around the world, while at the same time gain valuable career experience.
I highly recommend that you share this with interested students you may know. Happy Hooting!
