An addendum is the applicant's chance to explain not only disciplinary action experienced while in school but also any anomaly in your academic history.  Addendums are typically short and should be worded neutrally.  If any additional information is added, it should just be a brief mention of what you have learned from the experience.

Q: Why write an Addendum if I got in trouble only one time?

A: Strong Addendums identify the problem that caused the anomaly. It helps to explain how you learned or addressed the situation. 

Law schools don't expect students to be perfect! The most important thing to understand is to be honest if you have made some mistakes along the way. Most infractions are minor. You can and should address it in an Addendum if you have had either a minor infraction or bad semester that hurt your GPA.  

Had an incident that was expunged? Mention it in the Addendum, just in case.

• Worried that there was an instance that may have affected your quality of life or your academic performance? Mention it.
• Had a particularly bad semester academically? You can mention it here, as long as it is brief.
• Got a great excuse or think someone else is to blame? Forget it. Mention the incident in the Addendum, but don’t write it in a way that sounds as though you are making excuses or are blaming others without taking any personal responsibility.
• Title the document “Addendum,” add your name, include your LSAC number and then place it in the appropriate order in application packet. (Based on the specific law school)
