The members of the Executive Board are elected for a two-year term by the SOL members at the SOL biannual International Congress. In order to be elected on the SOL Board one has to be an active member of SOL, present at the Congress, nominated by other SOL members, and accept the nomination. In order to ensure renewal, but also continuity, anyone elected for President first serves as Vice-President for two years, then as President for another two years, and finally as Past-President for another two years.
