Getting involved does not require formal qualifications. Many of Cochrane's contributors work in research or healthcare institutions, but many others get involved simply because they are interested in a particular area of health, or in Cochrane's work generally. Some people work on Cochrane projects during working hours, others in their spare time, in workplaces or at home. Cochrane contributors come from everywhere - more than 130 countries around the world. Everyone can get involved and everyone benefits.
