The Boy Scouts of America have now announced that transgender children are allowed to join them.
This follows an incident last year where a child was turned away from the Scouts in New Jersey. His mother Kirstie Maldonado went public after her son Joe was asked to leave because he was transgender.
The organisation, which dates back to 1910, said the change had been made because of the national discussions on gender identity in the US.
Their statement, which can be found on their website, was also announced on YouTube by the chief scout executive, Michael Surbaugh.
This decision came into force immediately from the announcement yesterday, and has been welcomed by gender equality groups.
