We comment on methodological issues in the use of correspondence testing for discrimination in access to employment—that of submitting identical CVs to employers, but differing by the name (implying their ethnicity) of the candidate. After contrasting changing social structures in Britain and The Netherlands regarding ethnicity and Muslim integration, we report two case studies using correspondence testing for discrimination in employment involving a Muslim woman (in Manchester, England) and a Muslim man (in Rotterdam, Netherlands), outlining the recent socio-political situation concerning ethnic relations in The Netherlands. The methods used indicated apparent discrimination in employment involving both applicants. However, the novel methods we have employed require further verification using both traditional and novel methodologies. Findings from the two case studies are discussed and compared, with further research proposed.
