Clubs present excellent opportunities to practice their target language outside of the classroom. From the standard “speaking,” or “discussion,” club to clubs focused on film, culture, or sports, such activities can provide valuable supplemental instruction and practice opportunities to those studying language. With many such endeavors being informal, however, assessment of participants may prove difficult for those organizing, administering, and facilitating club meetings. This presentation will discuss approaches to assessing individual students, groups of students, and the success of clubs overall. It will also examine assessing clubs from the standpoint of sustainability, and discuss approaches which may allow for success in both regards.
