ACF Regionals is a regular difficulty college quizbowl tournament produced every year by ACF and held concurrently at multiple locations throughout North America and the United Kingdom. It is similar to ACF Fall in terms of format, and packet writing requirements. Regionals typically takes place in late January or February.
Since 2015, Regionals has served as a qualifier for ACF Nationals. Teams can qualify for Nationals by hosting a Regionals site, providing an editor for the question set, winning the overall or undergraduate title at their Regionals site, or obtaining a sufficiently high A-value.
ACF Regionals was produced from 1991 to 1997 by the now-defunct Academic Competition Foundation. The Foundation was replaced in 1997 by the Academic Competition Federation, which has edited the tournament ever since.
As of 2018, ACF Regionals is typically considered to lie towards the upper end of "regular difficulty," though this identity has changed over time. It was once the case that "Regionals difficulty" had its own definition above regular, though in the late 2000s Regionals came to be seen as the benchmark for measuring regular difficulty tournaments . ACF Regionals questions got more difficult for several years, but 2008 ACF Regionals was noticeably easier than the 2007 incarnation, and was in fact statistically easier than NAQT Sectionals of the same year. The 2018 iteration was generally considered to be quite difficult, and prompted some to suggest a bifurcation into "standard" and "qualifier" tournaments, with Regionals being the benchmark for the latter category.
