This research note is based on the evaluation of the Comenius project Teacher-IN-SErvice-Training-for-Roma-inclusion ("INSETRom"). The project represented an international effort that was undertaken to bridge the gap between Roma and non-Roma communities and to improve the educational attainment of Roma children in the mainstream educational system. The evaluation of the project showed that such projects can impact a teacher's confidence and attitudes, but that implementing new insights poses many challenges. (Contains 3 notes and 7 figures.)
