International Softball Congress

The International Softball Congress (ISC) is a non-profit association for the promotion and administration of men's and boys fastpitch softball throughout North America with athletes coming from all over the world.

The ISC was formed in 1958 as an amalgamation of the National Softball Congress and the International Softball League.

The ISC World Tournament is an annual tournament held each August to crown the best softball club in North America.

Teams from six regions (US East, US Central, US West, Canada East, Canada West, International) are represented at the World Tournament. The ISC allocates berths by region to qualifying tournaments throughout North America. Teams gain entry by winning one of the allocated berths or by accepting an at-large invitation. The current format has 48 teams taking part in a modified double elimination bracket. The first 16 teams eliminated are relegated to the ISC II Tournament. The ISC II Tournament of Champions originally began play in 2002 as a separate tournament for second-tier teams. The two tournaments were amalgamated for the 2010 tournament in Midland, Michigan.
