Register to Volunteer: APTCC, ETCC, and ITCC

This year, be a part of the action by volunteering for the ISA 2023 Tree Climbing Championships. ISA’s return to these essential events needs your help to host successfully. Grow your network and engage with international volunteers, competitors, and attendees in a weekend of camaraderie and competition.

We have opportunities to volunteer for APTCC, ETCC, and ITCC. See below for more information about when ISA will host these events and the link for volunteer opportunities.

  • The Asia Pacific Tree Climbing Championship (APTCC) will take place 27 – 29 April in Changi, Singapore. The deadline to register is 24 March 2023.
  • The European Tree Climbing Championship (ETCC) will take place 29 June – 2 July 2023. The deadline to register is 26 May 2023.
  • The International Tree Climbing Championship (ITCC) is 11 – 13 August Albuquerque, New Mexico. The deadline to register is 30 June 2023.

There are many opportunities to volunteer within each Tree Climbing Championship (TCC)—competition, logistics, and Arbor Fair. All levels of knowledge and skill are welcome.

To volunteer for the competition events, you must have a membership in good standing with ISA that is current during the competition dates. You do not have to be a member to volunteer for the non-competition events (Arbor Fair and Expo) held in conjunction with the ITCC.

ISA CEU opportunities are available at the event for select volunteer positions, and specific events within the TCC. You will have the chance to share your volunteer background and preferences with us when you submit your registration. To volunteer at any or all of the above-listed TCCs, click here.
