Wellcome has evolved its approach to research careers and reviewed the use of time-post qualification as an eligibility criterion. Time based eligibility criteria do not always accurately reflect research maturity and stage of independence, particularly when researchers have moved fields or had career breaks. In order to provide greater flexibility and clarity, we have removed years of post-doctoral experience as an eligibility criterion. In keeping with the partnership, The Royal Society has agreed to these changes for the Sir Henry Dale scheme.
