Almost a third of the law schools require a Dean's letter, which is sometimes referred to as a Dean's recommendation or certification (form). Such document is a verification that an applicant is or was a student in good standing at the institution that s/he is attending or graduated from.
Carefully review applications for the schools to which you wish to apply to assess your need for such a document since not all schools will require it. At UM, your school/college dean's or advising office usually handle Dean's letters. For example, the LSA Office of the Assistant Dean for Undergraduate Education and Student Academic Affairs is responsible for providing dean’s recommendations on behalf of the college (outside of the Honors Program or Residential College). Currently LSA enrolled students and alumni with a valid umich.edu email address may find the form to request a dean’s recommendation here. All LSA dean’s recommendations are sent electronically. Processing can take up to two weeks at periods of peak demand. See details and send questions to email@example.com.
Follow schools' directions for returning the Dean's letter or completed form. Remember that if you have the Dean's Letter sent back to you to include with your other application materials, the envelope must remain unopened.
