Although the quality issue has become a central preoccupation in other doma
ins of higher education, current internationalisation policies and practice
s in higher education have developed without much concern for quality assur
ance. The central thesis of this paper is that we have come to a point in t
he development of higher education where internationalisation policies and
practices face the limits of their development unless the quality challenge
is addressed in all its consequences. The paper first provides an overview
of contemporary forms of and recent developments in internationalisation i
n higher education. From more or less `traditional' forms such as student a
nd teaching staff mobility, internationalisation policies and practices now
adays move into activities such as exporting higher education via branch ca
mpuses and institutional co-operation, developing transnational university
networks and virtual delivery of higher education, and the harmonisation of
higher education systems. In these recent developments several issues and
challenges arise, which in one kind or another have direct links to the qua
lity challenge. The quality of internationalisation policies and practices
itself is an important problem, but of more importance are the issues of th
e recognition of foreign diplomas and degrees and the recognition of credit
s and credit-transfer. This paper takes a critical stance towards for examp
le the ECTS, which tries to solve these issues without much concern for qua
lity. The way out lies in an integration of internationalisation policies a
nd general quality assurance practices at institutional and policy levels.
