WATOC organizes a tri-annual world congress (most recently in 2002 in Lugano, Switzerland; next to be in 2005 in Cape Town, South Africa) and numerous smaller conferences on more specialized topics.
The association awards two yearly medals: the Schrödinger Medal to "the outstanding computational chemist in the world who has not previously received this award", and the Dirac Medal to "the outstanding computational chemist in the world under the age of 40".
