There are numerous professional organizations for student affairs at the national, regional, and international levels. These organizations serve many functions to the profession including, guidance for best practices across the field, professional development and shared learning, research or grants to further service development, and advocacy on current issues that influence professional practice and student life. In addition, many student affairs professionals participate in associations that are either more general (embracing higher education administrators generally) or specific to a particular sub-field such as residence life or student health. At the international level, professional organizations for student affairs include the International Association of Student Affairs and Services, which was established in 2010.
