The University of Oregon is home to three student-run a cappella groups: Divisi, a treble ensemble; On the Rocks, a TTBB ensemble; and Mind the Gap, a mixed ensemble. All three groups have competed numerous times in the International Championship of Collegiate A Cappella (ICCA). On the Rocks placed 3rd at ICCA finals in 2002 and 2nd in 2003. Divisi has competed at ICCA finals three times – the only treble ensemble in the world to do so – in 2005, where they placed 2nd, as well as 2010 and 2016. In 2020, The A Cappella Archive ranked Divisi at #14 all-time among ICCA-competing groups, as well as the highest-ranked treble ensemble.
