There are many ways to evaluate director performance. The most common include: (a)  self-evaluations by the directors themselves, usually through a written survey; (b)  evaluations by the board chair, or the chair of the governance committee – either in writing or through a one-on-one interview; (c)  peer evaluations by fellow board members and the executive officers through written surveys; and (d)  external evaluations by an independent governance consultant, after observing board interactions, spoking with the board chair and/or reviewing written feedback from board members and management. I would be happy to assist you. From compiling the internal feedback to conducting the evaluations externally, I can help.
