Develop a format that supports the goals of the critique. A server at a restaurant, for example, has a list of things he is supposed to do: suggest specific appetizers, deliver the meal in a specific order, and place the check on the table at a specific time. In this case, assigning points for successful completion of tasks is appropriate. If you are a critiquing a piece of art, the process will be more subjective, and you should ask open-ended questions.
Collect existing critique sheets. Examine what you like or don't like about them. Use them to determine what you think works and doesn't.
Develop questions. Keep your critique sheet comprehensive, but simple. If you ask too many questions, you respondents might feel overburdened and respond with incomplete answers. Don't ask the respondent to outline what's wrong. Instead, have her comment on what she observes. The concepts in Liz Lerman's "Critical Response Process" can help you develop an open-ended critique sheet that allows the recipient to gather information and come to his own conclusions.
If you are scoring or grading the recipient, develop a rubric with a scoring scale. Clearly delineate the difference between scores. Each major skill set should be evaluated. Staple the rubric to the back of the critique sheet so they stay together.
Include pertinent information, such as the recipient's name and project title. List goals, if they are relevant. If you are asking your respondents to critique according to a set of rules, write the rules on the critique sheet for easy reference.
