The Federal Rules of Evidence (FRE) make up one of the most heavily tested subjects on the bar exam — and one of the most misunderstood. Examiners love evidence questions because they reward precision: knowing the exact exception, the exact standard, or the exact rule number can be the difference between a right and wrong answer. Below are ten rules that show up again and again on bar exams and in law school finals.
1. Rule 401 & 402 — Relevance
Evidence is relevant if it has any tendency to make a fact more or less probable, and that fact must matter to the case. Relevant evidence is admissible unless another rule, the Constitution, or a statute says otherwise. This is the foundation every other evidence rule builds on.
2. Rule 403 — Balancing Probative Value vs. Prejudice
Even relevant evidence can be excluded if its probative value is substantially outweighed by unfair prejudice, confusion, or waste of time. Bar exam questions often test whether you can spot this balancing test versus a hard exclusionary rule.
3. Rule 404 — Character Evidence
Character evidence is generally inadmissible to prove a person acted in conformity with that character on a specific occasion. Exam questions love testing the exceptions, especially in criminal cases where a defendant can "open the door" to character evidence.
4. Rule 405 — Methods of Proving Character
When character evidence is admissible, it's usually proven through reputation or opinion testimony, not specific instances of conduct — except on cross-examination or when character is an essential element of a claim or defense.
5. Rule 607–609 — Impeachment
Any party, including the one who called the witness, can attack a witness's credibility. Rule 609 specifically covers impeachment by prior criminal conviction, with different standards depending on the type of crime and how much time has passed.
6. Rule 801 — Defining Hearsay
Hearsay is an out-of-court statement offered to prove the truth of the matter asserted. This definition is the gateway to one of the most tested areas of evidence law, and missing the definition often means missing the whole question.
7. Rule 803 — Hearsay Exceptions (Availability Immaterial)
This rule contains the bar exam's favorite hearsay exceptions: present sense impression, excited utterance, statements for medical diagnosis, business records, and public records. Many exam questions are really just asking you to match a fact pattern to one of these exceptions.
8. Rule 804 — Hearsay Exceptions Requiring Unavailability
Some exceptions only apply if the witness is unavailable to testify — like former testimony, statements against interest, and dying declarations. Confusing 803 and 804 exceptions is one of the most common bar exam mistakes.
9. Rule 901 & 902 — Authentication
Before evidence can be admitted, it generally must be authenticated — shown to be what the proponent claims it is. Rule 902 lists categories of evidence that are self-authenticating, meaning no extrinsic proof is required.
10. Rule 1002 — The Best Evidence Rule
To prove the content of a writing, recording, or photograph, the original is generally required unless an exception applies. Despite the name, this rule is narrower than it sounds — it only applies when the content of the writing itself is what's being proven.
