Central

The Ministry of Youth and Sports is in charge of policy in this area. However, it is not possible to speak of a coherent national youth policy in Tunisia at this stage although this is under development.[1]
Other ministries share responsibilities for those below 18 years of age, and the employment for those having reached the age of majority. Services to young people are delivered through centralised administrative units and a network of youth centres.
The Youth Observatory collects opinions of young people on their situation as well as on policy issues.
