There are no official documents defining quality standards in the field of youth volunteering in Slovenia. Minimum obligations of organisations when sending and receiving volunteers have been defined by the legislation within the Volunteering Act. 

Monitoring of the implementation of the Volunteering Act, in accordance with its Article 49, is done by inspectors of the Ministry of Public Administrations. Information Commissioner of the Republic of Slovenia monitors the protection of personal data.

In 2006 (amended in 2015), the cooperation between various voluntary organisations resulted in the development of a Volunteering Ethics Code (Etični kodeks organiziranega prostovoljstva), which contains basic guidelines and minimum standards that volunteers and their organisations are encouraged to comply with. The Code gives basic instructions for voluntary work, applicable to all types of voluntary organisations and volunteers. By signing the Code, an organisation obtains the right to use the logo of Volunteering as a symbol of the quality of their work, which is awarded by the Centre for the Development and Promotion of Voluntary Work of the Slovene Philanthropy. 

The Code of Ethics was developed with the assistance of different organisations and experts in the voluntary sector. The initiative benefited from the support of the Ministry of Labour, Family, Social Affairs and Equal Opportunities. Slovenian Network of Voluntary Organisations (Slovenska mreža prostovoljskih organizacij) states that as of 2025, 1688 organisations out of more than 2000 voluntary organisations included in the volunteering network, had signed the Code of Ethics.

The Code highlights key principles such as confidentiality, acting in the best interest of users, preventing power exploitation, and ensuring dignity, respect, and participation in voluntary work. It also upholds the reputation of voluntary work and guarantees volunteers' rights, including access to information, support, learning opportunities, and involvement in decision-making. Additionally, volunteers are entitled to expense reimbursement, insurance, and fair treatment within the organisation.

There is a registry of organisations offering volunteering opportunities to volunteers. The legal basis for the registry is the Volunteering Act, which in its Article 38 defines that all NGOs carrying out voluntary work have a right to enter the official registry. The electronic registry of voluntary organisations and organisations organising voluntary programmes contains the following information: registration number of a legal person and its data, the activity of a legal person and dates when an organisation entered the registry. 

Once a year the registered organisations need to submit a report on volunteering, including data on the number of volunteers by gender and age groups and the total number of volunteers’ hours depending on the type of volunteer work. Reports are submitted to the Agency of the Republic of Slovenia for Public Legal Records and Related Services for the purpose of national statistics. Aggregated data on volunteer work in Slovenia are submitted to the Ministry of Public Administration, which prepares a yearly report on the situation of volunteering in Slovenia and sends it to the Government of the Republic of Slovenia for its information.

The Ministry of Public Administration is mainly responsible for QA of voluntary activities. In general, the voluntary organisations under the provision of the Volunteering Act are obliged to provide training and tutoring if it is necessary due to the nature of voluntary work, or if the volunteer expressed the need for training. Voluntary organisations have no obligation to report about their quality assurance schemes to the competent ministries, unless their programmes are subject to co-financing from funds based on public calls for specific programmes.

To ensure the quality and effectiveness of volunteer work, it is crucial that volunteering is well-organised within volunteer organisations. Volunteers must have mentors and coordinators to guide them, provide support, and ensure they follow safety guidelines and protocols. Recognising this need, the Government is committed to promoting organised and high-quality volunteering. To this end, the Ministry of Public Administration has in 2025 re-launched the Call for proposals for the development and professionalisation of NGOs and volunteering, which will fund 60 positions for mentors and volunteering coordinators. This initiative aims to strengthen the structure, support, and professionalisation of voluntary work.
