Quality assurance (QA) for youth voluntary services is ensured by the 2007 Law on Youth Voluntary Service (loi du 31 octobre 2007 sur le service volontaire des jeunes, Art. 3), which defines the standards of quality. Furthermore, the monitoring and evaluation of voluntary services contribute to the quality assurance and improvement of the programmes. Organisations that want to offer a voluntary service programme must obtain an agreement through a decision by the minister in charge of youth policy. A commission, composed of representatives from different ministries and chaired by the director of the National Youth Service, advices on such agreements and evaluates an organisation's capacity and capability to fulfil certain requirements.

According to the law, organisations must: 

• Prove that they have no criminal record
• Demonstrate their ability and capacity to organise voluntary service programmes
• Possess the necessary human and financial resources.

Agreements are concluded for three years and define the maximum number of persons that can be enrolled. They can be extended for the same duration. However, an agreement can be withdrawn when an organisation does not fulfil the requirements defined by the agreement or if it endangers the volunteer's security and physical or mental health. This agreement withdrawal is supervised by the "Commission d'accompagnement du service volontaire".

Organisations are required to submit the following to the National Youth Service:

• A copy of the contract signed with the volunteer
• An annual report detailing the activities of the volunteers
• A final report for each case of voluntary service.

The National Youth Service is entitled to inspect the organisation at any time and to examine all accompanying documents to ensure compliance with the established standards.

Furthermore, all organisations operating within the European Solidarity Corps framework require accreditation. Additionally, there is the option to obtain the European Solidarity Corps Quality Label, which certifies that an organisation participating in the Corps can provide the necessary conditions for young people to engage in solidarity activities. In Luxembourg, while many organisations are accredited and can host volunteers, only the SNJ holds the quality label as a coordinating body, making it the principal coordinating organisation for voluntary services in the country. The process for obtaining the quality label is managed by the national agencies, such as Anefore in Luxembourg.
