This article chronologically reviews different contributions of the non-governmental organizations to the positive parenting initiative currently adopted in Spain. It starts with the theoretical framework adopted by UNICEF and the Oxford University researchers on the contribution of the International Agencies and NGOs to this subject that was implemented after the approval of the U.N. Convention on the Rights of the Child in 1989. These first proposals were directed to train parents according to the principle of 'the best interest of the child'. The article follows with initiatives developed mainly by UNICEF, WHO and NGO such as Save the Children, after that, in middle and low income countries. In the OCDE countries positive parenting programmes were also promoted. More recently, following the adoption of Recommendation 19 (2006) of the Council of Europe, several NGOs have developed numerous projects about parenting support services and programmes. Also, some positive parenting programmes, that are carried out in specifically Spain, by International and National NGO, are analysed. To conclude, NGOs have significantly contributed to the development of positive parenting in Spain, frequently in collaboration with public organisms from regional, autonomic and state levels.
