Categories will be judged by a small group of judges and they’ll be assigned based on judges’ expertise and always avoiding any conflicts of interest. Judges will read and score their allocated entry forms, considering any supporting materials submitted. Judges will be asked to give a score for each question within the entry form. These will be combined to give an overall score for each entry. All judges’ scores will then be combined, and only the highest-scoring entries will determine the shortlists. Judges will e-meet to discuss the highest-scoring entries and then agree on the winner for each category. Judges may, at their discretion, award a high commendation on each category.
To ensure that our awards are impartial, ethical, and transparent, we ask that our judges sign a charter agreeing to:
