While analysing the separation of Roma children from their non-Roma colleagues, often budgeting and financial allocation are not considered or are superficially analysed due to scarcity of data. How is segregation produced and reproduced? What are the mechanisms to support segregationist practices? How might budgeting and financial allocations contribute to segregation of Roma pupils? What policy tools have been used to separate Roma children from their non-Roma peers? What resources have been allocated to desegregate the schools? What kind of activities were funded? Who were those that supported school desegregation? What resources were made available by these actors? What types of policy tools were used to desegregate? Rostas’s paper will seek to answer these questions based on the experience of Roma school desegregation in Bulgaria, Czech Republic, Hungary, Romania and Slovakia.
