Many welfare states have increased their regulatory role, but little attention has been given to historical changes in the regulatory role of government ministries. This study embraces a mezzo perspective and explores the regulatory role of the Welfare Ministry of Israel in the field of personal social services, asking the following questions: 1) What are the changes in regulatory expectations versus practices over the last five decades? and 2) How can we explain these changes and their outcomes? The study is based on the qualitative analysis of comptroller reports and other resources. It reveals a growing gap between society’s expectations of the Ministry as a regulator and the Ministry’s capacities over five decades. Notably, it points to the variety of

regulatory spaces that have appeared in a regulatory welfare state. The Israeli case is relevant for other countries that have experienced processes of outsourcing and privatization in the welfare state and whose ministries had to change their role.
