Parexel has been ranked as the 'Top CRO to Work With' by investigative sites in the 2021 WCG CenterWatch Global Site Relationship Benchmark Survey. The biannual WCG CenterWatch survey explores the relationships among clinical trial sites and their sponsors and CROs and provides insight into overall performance.
 
The 2021 survey asked respondents to evaluate the 35 performance attributes identified by sites as most important to a successful site-CRO working relationship, with Parexel receiving the highest 'excellent' scores across the 35 performance attributes in six working relationship categories among all 29 CROs included in the survey.

As part of the survey, sites also rated CROs on their overall reputation in the industry, with Parexel ranking fourth and one of only two to rank in the top five for both industry reputation and direct working relationship quality. Parexel’s performance in the survey further reflects the company’s continued strategic focus in supporting investigative sites to better deliver for patients.
