In a developing society, quality social services are an indicator of ensuring the well-being of the population. The quality of services represents an element of interest, both for the social worker and for the manager of a social assistance organization – the social services provider. At the moment, the reorientation of the social assistance system from just distributing social benefits and material aids to offering social services has changed a lot and has diversified the functions of the social worker. Given the continuous development of the social services network for disadvantaged individuals and families and varied needs of the population, the need for a large number of specialized professionals for the provision of quality services has emerged. Therefore, the study initiated is based on the analysis of quality standards and the evaluation process of social service providers, trying to bring to the fore the necessity of creating a culture of quality, in a social assistance organization. The quality of social assistance services is determined by the degree to which they meet the permanent needs of the applicants or beneficiaries. This can be evaluated by the time spent for the provision of services or by the degree of comfort provided by the respective services or by the effect they have on the health, safety, integrity, ensuring the needs of the people who benefit or are to benefit from social services. The minimum quality standards, developed and approved by the relevant ministry, are necessary to ensure quality social assistance services. These contain the minimum indicators of the services provided to the beneficiaries. The continuous improvement of the quality implies: quality results, which means, first of all, meeting the needs of the beneficiaries; monitoring the quality results, a process that takes place both retrospectively and prospectively; quality is the responsibility of the whole organization; quality and quality assurance must be focused on both process and results. The ISO 9001 standard specifies the general requirements for the development, implementation and improvement of quality management systems, in order to meet the clients' requirements. The ISO 9001 standard (through ISO 9001: 2015 certification) can be applied by any organization that wants to improve its functioning, regardless of its size or scope and it represents the most widespread management standard worldwide. In order for a service to be able to be organized and function successfully, it is necessary that it should be coordinated and controlled in a systematically manner, but also it should comply with the specified recommendations.
