What an Addendum Is — and Is Not

An addendum is a brief supplemental document that explains something in your application that requires context. It is not an apology. It is not a platform for litigating past circumstances or demonstrating that you have overcome adversity. It is a factual explanation — clear, short, and calibrated to close a question rather than open a discussion.

The threshold for writing one is simple: would an admissions reader see something in your file and reasonably wonder what happened? If yes, explain it. If not, stay silent. Applications are not improved by volunteers who confess without being asked.

The GPA Addendum

Write a GPA addendum when your undergraduate record contains something that requires external context to interpret fairly. A medical illness, a family crisis, a documented mental health episode, a death in the immediate family — these are legitimate subjects for an addendum. So is a transfer between institutions that affected your LSAC GPA calculation, or a single catastrophic semester surrounded by otherwise strong performance.

What does not warrant a GPA addendum: a consistently low GPA with no specific explanation, a downward trend without a clear cause, or academic difficulty that you attribute to immaturity or bad habits. Those are better addressed by letting your LSAT score do the work and perhaps a line in your personal statement about what changed.

Keep it to one page. State what happened. State when it ended or was resolved. Do not editorialize. Do not project forward to the lawyer you will become. Explain the past; let everything else speak for itself.

The LSAT Addendum

An LSAT addendum is appropriate when you have multiple scores with a significant spread — typically five or more points — and you want to explain the lower score rather than let it sit unexplained. Schools see all your scores. They calculate using the highest (since 2018), but a reader who sees a 158 followed by a 172 will wonder what happened in the first sitting.

If the lower score reflects genuine circumstances — testing anxiety exacerbated by a specific situation, illness, a documented accommodation issue — explain it briefly. If the lower score reflects preparation level and the higher score reflects what you can actually do, say that plainly. "My first attempt was underprepared. My second reflects five months of structured study." That is sufficient. That is honest. That is all they need.

The Character and Fitness Addendum

Every law school application asks character and fitness questions about criminal history, academic dishonesty, and professional conduct. If you answer yes to any of them — and you should answer honestly, because bar applications ask the same questions and the consequences of inconsistency are severe — you must provide a full explanation.

This addendum is different from all others. It is not optional, and the bar for what it needs to contain is higher. Be complete. Describe what happened, what the outcome was, and what you have done since. Do not minimise. Bar associations routinely deny admission not because of the underlying incident but because of how the applicant disclosed it — partially, evasively, or with apparent lack of remorse.

If your character and fitness history is complicated, consult an attorney before you apply. This is the one area where professional guidance is worth the cost.

Gap Year and Employment Explanation

If your résumé contains a period of unexplained time — a gap year, an extended period between graduation and employment, a career pivot that looks abrupt — a brief note clarifying it is appropriate. Admissions readers notice gaps. They will draw their own conclusions if you do not provide one. In most cases, one to two sentences is enough. You do not owe anyone a detailed accounting of a difficult period in your life; you owe them enough context to understand your file.

What All Good Addenda Have in Common

They are short. One page is the ceiling; half a page is often better. They are factual rather than emotional. They close the question rather than expand it. And they are written as if the reader is a thoughtful professional who will extend reasonable good faith — not as if the reader is an adversary who must be convinced.

The admissions reader is not looking for a reason to reject you. They are looking for a reason to feel confident about admitting you. An honest, well-written addendum gives them that confidence. An anxious, over-explained one does the opposite.
