Multiple raters are sometimes used in the domestic context – e.g. the 360-degree feedback process. It has been argued that, given the cross-cultural complexity of the foreign assignment, a team of evaluators should be used for performance appraisal. For example, Gregersen et al. found that most firms (81 per cent) in their survey of HR directors in US multinationals used more than one rater when assessing expatriate performance. The immediate superior (in either the home or host country), the expatriate as self-rater, and the HR manager (either home or host-country based) were commonly used as multiple evaluators of US expatriate performance. The 2010 Brookfield Global Relocation Trends Survey Report found that per cent of respondents reported using performance reviews in the host country, per cent used reviews in both host and home countries and per cent used performance reviews in the home country. For the virtual assignment situation, the use of multiple appraisers would most likely be the most accurate way to determine performance. However, the availability of knowledgeable, trained raters may constrain the approach taken in the international context
