The Academy Council of 6 February 1991 set up the following rules for the Koyré medal and the prize for young historians.

The Koyré medal is awarded for a scholar’s career contribution rather than for a particular achievement. The candidate needs not to be a member of the Academy. Nomination of a Koyré medallist must be made in writing by a member of the Academy. The Council will choose the medallist via a mail ballot repeated until an absolute majority is attained. A decision will be made between General Assemblies and the award made at the next General Assembly.

The prize for young historians will be decided and awarded on the schedule that applies to the Koyré medallist. The prize rewards a first work in the history of science. Candidates can put themselves forward or be nominated by a member of the Academy. In either case the case must be submitted in writing and the work proposed for the prize sent to the Academy. The Council will decide the winner at one of its regular meetings by a majority vote of the members present. The prize will consist of a diploma and a cheque, the amount of which may vary from time to time.
