The institution of national and inter-country adoption has greatly developed in recent years, becoming a phenomenon of special relevance that has inspired many studies and research initiatives.
The ChildONEurope network has therefore decided to set up a working group of experts of receiving countries and countries of origin nominated by the ChildONEurope partners in order to explore the most relevant issues at stake.

The first work that was carried out by the group in 2006 was the drafting of a comparative report addressing the need for knowledge and information sharing on legislation, data and practices on issues like: typologies of adoption, criteria for the suitability of singles and couples wishing to adopt, prerequisites for the declaration of the status of adoptability, operational protocols, post adoption services
The group decided then to organize a European Seminar on 26 January 2006 on post adoption services, in order to illustrate and compare approaches, models, and support services to adoptive families in the EU context and through the drafting of Guidelines on Post-adoption Services. The Guidelines, published in 2007 show that in most of the countries involved in inter-country adoption, the topic remains insufficiently or inadequately addressed and still requires promotion. The Guidelines aim therefore to facilitate this process through a theoretical and practical analysis, establishing first the context, rationale and goals of post-adoption services and then studying their practical issues.

More recently, ChildONEurope contributed to the drafting of a Comparative Report on International adoption in the European Union awarded to the Istituto degli Innocenti of Florence by the European Union Parliament (Contract notice 2008/S 20-024926). The report, issued in 2009, presents comparative research on the different and common elements of the national legislation concerning intercountry adoption in the EU countries aimed at verifying the opportunity to set up a common procedure for adoption in the EU. The report analyses the social aspects related to adoption as well as the statistics.
