Card Tag

A card tag is the one-sentence (occasionally two-sentence) claim a debater places at the top of a piece of evidence, sometimes called a "card," before the citation and the underlined or highlighted excerpt from the source. The tag tells the judge and the opposing team what argument the debater believes the evidence proves, framing how the underlined text should be read when the debater reads it aloud during a constructive or rebuttal speech.

Tags follow a fairly standardized structure in U.S. high school and college policy debate, which has used cut-card evidence since at least the mid-20th century. A typical card on a flow sheet appears as: tag → citation (author, qualifications, date, source, page or URL) → body text with underlining and highlighting. The tag is what gets written on the flow, the running shorthand record of arguments, so a strong tag is concise, active-voice, and tracks the specific warrant in the evidence rather than overclaiming.

Common conventions include:

• Specificity: Tags should name the actor, mechanism, and impact (e.g., "U.S. semiconductor export controls collapse Taiwan's chip leverage") rather than vague slogans.
• Honesty to the card: Tag inflation—writing a tag the underlined text does not support—is grounds for a power-tagging or clipping-adjacent indictment, and judges have voted teams down for it.
• Tag-team flow utility: Because partners and judges flow from the tag, debaters often standardize verbs (causes, solves, turns, links).

Tags differ from analytics (unevidenced spoken arguments) and from the citation, which records bibliographic information. In the National Speech & Debate Association and National Debate Tournament communities, evidence ethics rules require that the underlined portion actually defend the tag's claim; misrepresentation can trigger a loss and, in egregious cases, sanctions.
