Some of the commonalities and differences may be in fact be due to national and cultural differences. For example, the capacity of many North American (and particularly US) universities to engage in service learning as part of progressive charters in communities large and small is part of a long-standing tradition absent elsewhere. The tradition of service learning is almost entirely absent in the UK, Australia, or New Zealand, (and of limited significance in Canada) where the State has traditionally played a much stronger role in the delivery of community services and information.
