PI's governing body is the Board of Trustees. The primary responsibility of the Board is to provide strategic leadership by formulating and reviewing PI's strategic aims in consultation with staff, setting overall policy, regularly evaluating the charity's performance, and ensuring compliance with UK law. The board meets up to four times a year.
New Trustees are recruited through an open application process. Appointments are made not only on the basis of individual merit, but also taking into consideration the existing expertise and experience of the Trustees, as well as PI's equal opportunities policy.
