Roma, today perceived as the most numerous European minority, face marginalisation and exclusion. Education is considered to be one of the focal points for improvement, and numerous studies have analysed and reported on the educational situation of Roma. Several studies have argued that Romani cultural values are not compatible with institutional schooling and that Romani families perceive schools as an alien institution. Other studies have drawn upon cultural-ecological theory (CE theory), developed by Ogbu and colleagues, and argue that the Romani cultural frame of reference is oppositional to academic success and thus suggest that successful Romani students distance themselves from Romani culture. The paper discusses the application of CE theory in the context of the academic discourse about the educational achievement of Romani students. Drawing on interviews with Spanish Romani university students, the paper argues that Romani students themselves challenge the assumption that educational success leads to cultural alienation.
