NAQT Invitational Series

IS Sets (short for Invitational Series) are 15-packet question sets produced by NAQT, typically for use at regular season high school quizbowl tournaments. Generally, an IS set is used by many different tournaments around the country on different dates during the school year.

NAQT also produces 12-packet "A-level" IS sets, which are easier and are intended for first- and second-year high school players.

Reception

Some elite high school teams have criticized IS Sets for being too easy, or for being funn.

Many people prominent in the college game have criticized college tournaments for using IS Sets. Their arguments include the fact that questions produced for high school players are inappropriate for a college audience, and that these tournaments might sap funds from tournaments aimed at college teams.
