Most Commonly Tested Evidence Issues

Hearsay is roughly a third of any evidence exam, and it is the issue students lose the most points on because they collapse three separate steps into one conclusion. After hearsay, the highest-yield areas are character and other-acts evidence, impeachment, the Confrontation Clause, expert testimony, and authentication/best evidence. Relevance under 401-403 is not usually a standalone issue but it is the tiebreaker sentence that finishes almost every admissibility discussion.

One variation matters: most schools and the NCBE test the Federal Rules of Evidence, but a few jurisdictions test their own codes on essays. California is the big outlier — the California Evidence Code has no Rule 403 'substantially outweighs' formulation identical to the FRE, treats prior inconsistent statements as substantive evidence without an oath requirement, and has no residual exception. If you are sitting the California bar or a California-taught course, learn the CEC/FRE distinctions as a separate list. Ask your professor whether the exam is FRE-only, and whether it is open-rulebook, because that changes how much rule text you must memorize versus apply.

Use a fixed sequence and write it out every time. First, identify the out-of-court statement and the declarant by name. Second, ask what it is offered to prove — this is where non-hearsay purposes live: effect on the listener (notice, fear, reasonableness), verbal acts and legally operative words (contract formation, defamation, bribe offers), circumstantial evidence of the declarant's state of mind, and impeachment. Only if the statement is offered for its truth do you move to Rule 801(d).

Third, check the exemptions: prior inconsistent statements under oath at a proceeding (801(d)(1)(A)), prior consistent statements offered to rebut a charge of recent fabrication or to rehabilitate on another ground (801(d)(1)(B), and remember Tome v. United States, 513 U.S. 150 (1995), requires the statement to predate the motive to fabricate for the rebuttal branch), statements of identification (801(d)(1)(C)), and the five opposing-party categories in 801(d)(2). Coconspirator statements under 801(d)(2)(E) require a conspiracy, during and in furtherance; the judge decides by a preponderance under 104(a) and may consider the statement itself, but the statement alone is not enough — Bourjaily v. United States, 483 U.S. 171 (1987), plus the rule's final sentence.

Fourth, work 803, then 804, then 807. Fifth, if the evidence has layers — a police report quoting a bystander — apply Rule 805 and find an exception for each layer. Sixth, if this is a criminal case and the evidence is offered against the defendant, do the Confrontation Clause separately. Finally, do Rule 403 and, if the evidence is admissible for one purpose only, request a limiting instruction under Rule 105.

Examiners favor exceptions with tight, checkable elements and a common trap.

For 804, do not forget the threshold: the declarant must be unavailable under 804(a), and unavailability caused by the proponent's wrongdoing does not count.

Treat it as a separate paragraph, never as part of the hearsay analysis. Under Crawford v. Washington, 541 U.S. 36 (2004), a testimonial hearsay statement is inadmissible against a criminal defendant unless the declarant is unavailable and the defendant had a prior opportunity to cross-examine. The controlling question is whether the statement is testimonial, which turns on the primary purpose test: Davis v. Washington, 547 U.S. 813 (2006), and Michigan v. Bryant, 562 U.S. 344 (2011), separate statements addressing an ongoing emergency from those aimed at proving past events. Ohio v. Clark, 576 U.S. 237 (2015), held a young child's statements to a preschool teacher nontestimonial.

The forensic-report line is heavily tested: Melendez-Diaz v. Massachusetts, 557 U.S. 305 (2009), and Bullcoming v. New Mexico, 564 U.S. 647 (2011), require the analyst who made the certification to testify, and Smith v. Arizona, 602 U.S. 779 (2024), holds that a substitute expert who conveys an absent analyst's statements for their truth triggers the Clause. Also know the Bruton line — Bruton v. United States, 391 U.S. 123 (1968), Richardson v. Marsh, 481 U.S. 200 (1987), and Gray v. Maryland, 523 U.S. 185 (1998) — for codefendant confessions in joint trials.

Two mistakes to avoid: applying the Clause in civil cases or to evidence offered by the defendant, and applying it to statements that are not hearsay at all. Nontestimonial or non-truth statements raise no Confrontation issue.

Start by asking whether the evidence is offered to show action in conformity. If yes, 404(a)(1) excludes it in civil cases and generally in criminal cases unless the defendant opens the door under 404(a)(2) (the mercy rule), which then lets the prosecution rebut with reputation or opinion, and cross-examine the character witness about specific instances under 405(a) — the structure of Michelson v. United States, 335 U.S. 469 (1948). Specific instances are only allowed on direct when character is an essential element (defamation, negligent entrustment, entrapment). Rules 413-415 permit propensity use of prior sexual assault and child molestation in those cases.

For 404(b), articulate the non-propensity purpose specifically — motive, opportunity, intent, preparation, plan, knowledge, identity, absence of mistake — and then apply the low admission threshold from Huddleston v. United States, 485 U.S. 681 (1988): the judge asks under 104(b) whether a jury could reasonably find the act occurred by a preponderance. The 2020 amendment requires the prosecution to articulate the purpose and the chain of reasoning in its notice. Finish with 403 and a limiting instruction. Old Chief v. United States, 519 U.S. 172 (1997), is the leading case on an available stipulation defeating the need for the prejudicial version of the proof.

On impeachment, keep 608 and 609 apart. Rule 608(b) allows cross-examination about non-conviction acts probative of truthfulness but forbids extrinsic evidence. Rule 609(a)(2) makes convictions involving a dishonest act or false statement automatically admissible; 609(a)(1)(B) applies reverse balancing to a criminal defendant's other felony convictions; 609(b) applies reverse balancing plus notice to convictions more than ten years old. Luce v. United States, 469 U.S. 38 (1984), requires the defendant to testify to preserve the issue, and Ohler v. United States, 529 U.S. 753 (2000), holds that preemptively introducing the conviction waives the objection. For prior inconsistent statements, 613(b) requires an opportunity to explain before extrinsic evidence, except for opposing-party statements.

Rule 702 was amended effective December 1, 2023: the proponent must show by a preponderance that each requirement is satisfied, and that the opinion reflects a reliable application of the methodology to the facts. Cite Daubert v. Merrell Dow Pharmaceuticals, 509 U.S. 579 (1993), for the reliability factors, Kumho Tire Co. v. Carmichael, 526 U.S. 137 (1999), for extension to technical and experience-based experts, and General Electric Co. v. Joiner, 522 U.S. 136 (1997), for abuse-of-discretion review and analytical gaps. Under 703, an expert may rely on inadmissible facts if experts in the field reasonably would, but those facts reach the jury only if their probative value in helping evaluate the opinion substantially outweighs their prejudicial effect. Rule 704(b) bars an opinion on whether a criminal defendant had the requisite mental state.

Authentication questions almost always involve text messages, emails, or social media; the answer is Rule 901(b)(4) distinctive characteristics plus contents, or 902(13)-(14) certification for electronic records and copies from electronic devices. Best evidence under 1002 applies only when the content of a writing, recording, or photograph is at issue; duplicates are admissible under 1003, and 1004 excuses the original when it is lost, destroyed in good faith, or in the opponent's control.

Privilege is federal common law under Rule 501, with state law supplying the privilege for state-law claims in diversity. Test the attorney-client elements, the crime-fraud exception, and the two spousal privileges: the testimonial privilege held by the witness spouse under Trammel v. United States, 445 U.S. 40 (1980), and the confidential marital communications privilege that survives divorce. Rule 606(b) bars juror testimony about deliberations, with the racial-bias exception from Peña-Rodriguez v. Colorado, 580 U.S. 206 (2017).

Organize by item of evidence, not by rule. For each item, write a short heading naming the evidence, then relevance, then the specific exclusionary rule, then any exception, then 403, then the limiting instruction. Give every plausible ground for admission and every plausible objection; graders award points for the alternative theory you spotted, not for confidence in one answer.

Two habits raise scores immediately. First, name the declarant and the offering party in every hearsay sentence — 'offered by the prosecution against Dan to prove the light was red' — because that single clause resolves the truth question, the 801(d)(2) question, and the Confrontation question at once. Second, do not skip 403 just because you found an exception; a sentence explaining why the danger of unfair prejudice does or does not substantially outweigh probative value is often an explicit rubric point.
