Student Leader magazine, the official publication of the American Student Government Association (ASGA), was a national leader in addressing diversity issues. In fact, since 1993, both Student Leader and sister-publication Florida Leader published many articles about how to make sure all students are represented by your SG, from increasing the recruitment and retention of people of traditionally marginalized backgrounds to providing broad educational services for campuses that help bring awareness to local and national issues.
If you type the word "diversity" into the search engine at the ASGA online article library, you'll find dozens of articles on this topic, and the ASGA links library guides members to organizations, lobby groups, speakers, and events which cater to this area as well.
ASGA also has a diverse board and "Ask the Experts Panel" who help students, adminstrators, and advisors improve SGs in hundreds of ways. We feel that having a staff of experts with different experiences, viewpoints, and backgrounds helps us to better serve our ASGA members, who come from a wide array of backgrounds and experiences themselves.
