A questionnaire was sent to the heads of internationalization in the business schools of all U.K. universities. Sixty-five replies were received. The document covered, inter alia, the internationalization activities undertaken by the respondents' schools, the intensities with which internationalization had been implemented, motives for internationalizing, approaches adopted (gradualistic vs. simultaneous), possible links with graduate employability, and the role of innate predilections toward internationalization held by senior business school managers. A schematic model intended to explain the speed, extent, and intensity of a business school's internationalization was developed and tested. It transpired that levels of internationalization activity within the sample institutions were substantial. The degree and/or speed of internationalization within a business school appeared to depend significantly on the financial situation of the host university, managerial inclinations favoring internationalization, financial dependence on foreign students, the desire to attract greater numbers of students from overseas, the size of the business school and the age of its host university, and the belief among senior managers that an internationalized curriculum improved the employment and career prospects of British born as well as foreign students.
