Donations to the ICF help us carry out our work, offering high quality educational resources including our online content and supporting the ICF Symposium series.  All ICF Directors and Officers are strictly volunteers and thus you can be sure that your donation will go towards the development and maintenance of our charitable programs.

The ICF is a 501(c)3 public charity, making every gift to the organization tax deductible to the fullest extent of the law.
