Shortlist your candidates against your agreed set of skills and qualities. Don't be swayed by impressive CVs – look for applicants who meet your criteria and will bring new and different perspectives to your existing board.
Plan your interview process so it goes smoothly. Ask a set of structured questions to assess applicants' interest in your charity, their fit with your charity's values and to explore how they could use their skills and experience to help board discussions. Assessing their responses against clear critieria will help you choose the best candidates and make the process fair. It also makes it easier to turn down people who are unsuitable.
Interviews are a two-way street: applicants will want to find out more about your charity, the other trustees and your board culture. Give them opportunities to do this, and make the interview a positive experience for them
