Debate Rubric (Grades 9-12)
A classroom debate is graded in real time or not at all, so every descriptor here is something you can hear from the back of the room: claims stated, sources named, opposing points answered or dropped. It fits a two-team format with openings, rebuttals, and closings, and adapts to Lincoln-Douglas by scoring each debater alone.

| Criterion | Exceeds | Meets | Approaching | Beginning |
|---|---|---|---|---|
| Opening Argument and Case25 points | 23-25 ptsStates the team's position in the first sentence, previews distinct numbered contentions, and defines the key terms the resolution turns on. | 18-22 ptsStates a clear position with at least two distinct contentions, though terms are left for the rebuttal to fight over. | 13-17 ptsPosition is identifiable but contentions overlap or are read as one undifferentiated speech. | 0-12 ptsOpening restates the resolution or wanders without a stated position. |
| Evidence and Reasoning25 points | 23-25 ptsEach contention is supported with a named source, statistic, or documented example, and the speaker explains how the evidence proves the claim. | 18-22 ptsMost contentions carry evidence with sources named, with reasoning present but compressed. | 13-17 ptsClaims are supported by hypotheticals and common-sense assertions rather than checkable evidence. | 0-12 ptsNo sources or examples offered, or evidence cited does not relate to the claim it follows. |
| Rebuttal and Responsiveness25 points | 23-25 ptsDirectly answers the opponents' strongest arguments by restating them accurately, then attacking the evidence or reasoning, and notes any point the other side dropped. | 18-22 ptsAnswers at least two opposing arguments specifically rather than repeating the opening case louder. | 13-17 ptsRebuttal restates the team's own case and answers opposing arguments only in passing. | 0-12 ptsIgnores everything the other side said, or misstates their argument and attacks the misstatement. |
| Delivery and Decorum15 points | 14-15 ptsSpeaks from notes rather than a script, at a pace and volume the whole room follows, within time limits, and addresses arguments rather than the people making them. | 11-13 ptsClear and audible with occasional reading, inside the time limits, and consistently respectful. | 8-10 ptsReads a prepared text head-down, runs significantly over or under time, or lets frustration show as sarcasm. | 0-7 ptsInaudible or unprepared, or personal remarks about the opposing team replace argument. |
| Closing10 points | 9-10 ptsCrystallizes the round: names the two or three points the debate actually turned on and shows why they favor the speaker's side, without introducing new arguments. | 7-8 ptsSummarizes the team's strongest points and the weaknesses exposed in the other side's case. | 5-6 ptsRepeats the opening speech without reference to anything that happened during the round. | 0-4 ptsNo closing, or a closing that introduces brand-new contentions. |
Total: 100 points across 5 criteria.
How to use it
- Give both teams the rubric a week out and require contentions in writing the day before; the debate improves more from preparation than from any feedback afterward.
- Track dropped arguments on a flow sheet, two columns per side; criterion three cannot be scored honestly from memory.
- Time every speech visibly and enforce the limits; the discipline of the clock is half of criterion four.
What students most often get wrong
- Rebutting the opponents' weakest point at length while their strongest stands unanswered.
- Reading the opening case a second time and calling it a rebuttal.
- Winning the argument and losing the decorum points by delivering the win with a sneer.
