International Championship of Collegiate A Cappella

The International Championship of Collegiate A Cappella (ICCA), originally the National Championship of Collegiate A Cappella ("NCCA", a play on NCAA), is an international competition that attracts hundreds of college a cappella groups each year.

Founded in 1996 by former Tufts University Beelzebubs music director Deke Sharon and former Brown University Derbies member Adam Farb, the ICCA tournament takes place from January through April in nine regions: Northwest, Southwest, Midwest, Great Lakes, Central, Mid-Atlantic, Northeast, South, and United Kingdom.

The ICCA has been presented by Varsity Vocals since 1999, when the competition was purchased by Don Gooding (Contemporary A Cappella Publishing). The success of the ICCA produced a spin-off competition in 2005: the International Championship of High School A Cappella (ICHSA). Amanda Newman became owner of Varsity Vocals in 2008 and has since produced the events.

The 2006–2007 competition season was a focus of the book Pitch Perfect: The Quest for Collegiate A Cappella Glory, which followed three groups vying to win the Championship. The ICCA Finals were featured in the 2015 reality TV series Sing It On.

There are three to five quarterfinal events held in each of the eight American regions - the UK region goes straight to semifinals. The top two college groups at each quarterfinal advance to the semifinals in their respective regions. The winner of each semifinal is invited to participate in finals, currently held at the Beacon Theatre (the event has also been held in Lincoln Center for the Performing Arts, Carnegie Hall and The Town Hall Theatre), where they compete for coveted title of International Champion.

Each group prepares a short 12 minute performance (usually three songs) that best show the group's strengths. Primary focus is on a group's musical performance, but presentation is important so it's not unusual to see choreography involved as well. Groups generally range in size from 8-20. A panel of three to five trained judges evaluates the group's performance.

According to official Varsity Vocals documents, the aspects of vocal performance that are integral to a high-scoring ICCA performance include balance and blend, quality and inventiveness of arrangement, rhythmic accuracy, interpretation of song, intonation, solo interpretation, tone quality, dynamic precision, and diction. The first six of these concepts are graded on a 1-10 scale, while the last three are graded on a 1-5 scale. These numbers are added up, then added to the number for the next section, Visual Performance. The total possible score for this section is 75.
