SIOP has updated its host destination selection procedure. SIOP no longer uses an open formal bidding process for congresses. Instead, host destinations are solicited directly by SIOP and selected jointly with our Professional Conference Organiser (PCO). Final decisions on host cities are made jointly by the SIOP Board and the PCO. Selected destinations will be officially announced to members during the Annual Business Meeting.

While formal bids are no longer accepted, SIOP evaluates potential host cities based on the following logistical and infrastructure requirements:

• Capacity: Venue infrastructure suitable for 2,400–2,800 delegates.

• Local Leadership: A named Core Local Organising Committee (LOC) and a clear backing organization.

• Accessibility: Excellent air and ground transport connectivity, with accommodation preferably within easy walking distance of the venue.

• Housing & Affordability: Varied accommodation options across all price ranges and reasonable overall attendance costs.

• Scheduling: Strategic dates that avoid conflicts with other major international meetings or recognized religious holidays.

The scientific content of the SIOP Annual Congress remains entirely under the direction of the SIOP Scientific Committee.

As of 2029, SIOP considers global destinations without adhering to a rigid continent-by-continent rotation schedule.
