There is a big quantity of scout organizations in Ukraine. A few of them is local or regional, but only a few all-Ukrainian. National Scout Organizations of Ukraine are National Scout Organization of Ukraine PLAST, all-Ukrainian Organization SICH and all-Ukrainian Youth Organization SPOK. There was a competition among these 3 organizations for getting the membership in WOSM. 

For example, during all its history Plast tried to become a part of World Organization of Scout Movement. Until 1991 the drawback was the absence of independent state: every organization has to represent a country. But even after 1991 Plast couldn’t join WOSM and the reason for that was too much patriotism in the ideology which doesn’t allow young people from all over Ukraine to associate themselves with this organization and nonproliferation all over the territory of Ukraine (other accusations, such as comments to the statute, were more technical and could be corrected within a short time). World Scout Conference in Cairo in 1999 decided that Plast  can not apply for membership in WOSM due to the abovementioned reasons. 

In 2005 SPOK filled in the application to join WOSM, but 8 countries voted against this (according to WOSM Constitution if 5% of countries-members are against – it is enough for the organization not be accepted as WOSM member) and thus SPOK lost a chance to be a sole representative of Ukraine in the World Organization.

Through the mediation of representatives of World Scout Bureau in 2005, a joint meeting of the representatives of Plast, SPOK and the Eurasian Bureau was held, and there was decided to create a new organization that would allow Ukraine to become WOSM member. 

Officially, the organization was founded at Congress in 2007 with the name All-Ukrainian Youth Public Organization "National Organization of Scouts of Ukraine" (NOSU). Mr. Lev Zakharchyshyn was elected as a Chairman of NOSU, and his deputy – Mr. Valeriy Tantsyura. NOSU was registered by the Ministry of Justice of Ukraine by the order № 987/5 on October, 26, 2007. 

In 2008, NOSU applied for being accepted by World Organization of Scout Movement. The request was considered and satisfied NOSU was officially accepted into the World Organization of the Scout Movement on July, 1, 2008 at the 38th World Scout Conference in Korea.

Administratively NOSU is a member of Eurasia Region of WOSM
