There are a number of associations and groups for students to join at the university and within the city. There are numerous groups and associations based around interests such as a capella, choir, ballroom dance, cabaret, theater, debate, literature, pop choir, political organizations, sports, LGBT, international students, and social justice.  Study associations are connected to the student's department of study and offer social and academic options within the department. There are also student associations within the town, separate from the school.  These clubs were described as similar to American fraternities (but they are mixed-gender) and have a social focus. At many schools, ESN is focused on exchange students.  The university works closely with ESN to ensure that they provide opportunities for international degree students as well.  Activities include cultural events like international dinners, social events like theme parties and pub quizzes, travel, sports, and workshops. The University of Groningen conducts an introduction week for international students that provides information about the city as well as the options for involvement at the school.  Information is also provided on insurance and bike sales during that week. The evenings are full of parties introducing new students to social life. Groningen students can join the ACLO Sports Center for around 60 euros a year.  In addition to extensive facilities, they offer 48 different sports clubs. There are a number of resources for students on campus including tutors, student advisors, counseling services, career services, and an international service help desk.
