The organisation hopes a new non-religious alternative to the Scout Promise will better reflect the communities within which the movement works.
Generations of young people have pledged "On my honour, I promise that I will do my best, to do my duty to God and to the Queen, to help other people and to keep the Scout Law".
A new alternative wording would see the first part of the Promise tweaked to read: "I promise that I will do my best to uphold our Scout values."
Organisers said the Scouts were still committed to exploring faith and religion as a core element of its programme.
For nearly 50 years alternative versions of the words "Duty to God" have existed for faith groups such as Muslims, Hindus and Buddhists, but this is the first time the movement has introduced a Promise for potential members who are without a faith.
Graham Haddock, Chief Commissioner of Scotland said Scouting had an ambition to better reflect the make-up of the communities where it operates.
He said: "The option to make this new alternative Scout Promise opens membership to a large group of young people and adults with no avowed faith, who previously could not join and enjoy what Scouting has to offer, and helps to achieve this ambition.
"The recent Scottish census confirms just how many people fall into this group. At the same time, we have reaffirmed the importance of our core values, including faiths and beliefs, and restated the fundamentals that make Scouting special."
The move was welcomed by the Church Of Scotland, as well as non-faith group the British Humanist Association.
The Right Reverend Lorna Hood, Moderator Of The General Assembly Of The Church Of Scotland, said she was "delighted to learn that the Scout movement is to retain its traditional promise of duty to God and the Queen".
Andrew Copson, of the British Humanist Association, said: "Scouting has shown it genuinely wishes to be a movement open to all."
