出願締め切り日やエッセイ課題の確認も大切ですが、推薦状課題内容も確認していきましょう。レジュメやエッセイにて述べたコンテンツに信憑性を与える役割を果たすのが推薦状です。

Q. How does the applicant’s performance, potential, background, or personal qualities compare to those of other well-qualified individuals in similar roles? Please provide specific examples.

Q.Please describe the most important piece of constructive feedback you have given the applicant. Please detail the circumstances and the applicant’s response.

• The first letter of recommendation should come from a supervisor. We prefer that you use a current supervisor for this recommendation, although we understand that this may not always be possible. If you are unable to use your current supervisor, please explain the circumstances in the optional essay. Overall, we are seeking objectivity in the letter, and we want to hear from someone who can assess both your strengths and your weaknesses. If you work for a family business or own your own company, please try to secure a letter from a client or outside party who does business with you and can provide an objective assessment of you.
• The second letter can be professional in nature or come from an individual who has worked with you in an organization, club, or on a volunteer project. These letters can give us a different perspective of your skill sets outside of your professional environment. There is no preference on who supplies your second letter of recommendation; our only guideline is that it should add new and valuable insight to your candidacy.The letter of recommendation form is available electronically through the online application system. Once you access that system, you will be asked to provide the names and email addresses of your recommenders. We will then send them an email that includes the link to the online form that they will have to complete. Chicago Booth does not accept letters of recommendation via mail or fax.
