The first draft of these articles was modelled on those of the British professional society The Institute of Mathematics and its Applications. Consequently, they are quite involved and probably cover a lot of contingencies that will never arise. They have been examined by Council, and Council has approved them as a suitable set of initial articles. If and when revisions become necessary, the Articles can be revised by a General Meeting of the Institute.  The members are associated in the society according to the following ARTICLES OF ASSOCIATION.


1. If not inconsistent with the subject or context, certain words have specific meaning as given below:

WORDS                               MEANINGS

These presents                  These articles of Association, and the current regulations of the Institute.

The Council                        The Council of Management for the time being of the Institute.
Voting Member                A Fellow or Associate Fellow of the Institute.
The Office                          The registered office of the Institute, housed at FAU starting in 2017

               b) Hall Medals recognize extensive quality research with substantial international impact by Fellows of the ICA in mid-career. Recipients must not have reached age 41 before the end of the year for which they are nominated. At most two medals per year are awarded.

               c) Kirkman Medals recognize excellent research by Fellows or Associate Fellows of the ICA early in their research career, as evidenced by an excellent body of published research. Recipients must have earned their doctoral degree within the four years preceding the end of the year for which they are nominated. At most two medals per year are awarded.

               d) Instituted in 2016, Stanton Medal honours significant lifetime contributions to promoting the discipline of combinatorics through advocacy, outreach, service, teaching and/or mentoring. Letters of nomination should establish the significance, duration, and impact of the nominee’s contributions other than research. At most one medal per year is to be awarded, typically to a Fellow of the ICA.

83. Nominations for medal recipients: Each nomination for a medal is to be made by two or more Fellows of the ICA. Nominees for the Stanton medal must not be current members of the ICA Council. Nominees for an Euler, Hall, or Kirkman medal must be ICA members in the year for which they are nominated, and not current members of the ICA Council and not Honorary Fellows.

87.  Policy on Program Review and Accreditation: At this time, the ICA does not accredit programs and has no formal structure for program review.
