Your teen signed up for Impromptu because it sounded like the event with no homework. Then they learned how it works: draw a topic they have never seen, and give a full speech on it a couple of minutes later, with no notes.
Impromptu (IMP) is a speech event run by the National Speech and Debate Association (NSDA). The rules below come from the NSDA's 2024-25 High School Unified Manual and its guide for Impromptu judges. State leagues and local tournaments often set their own timing, so read the tournament invitation before your teen practices to a clock.
How an Impromptu Round Works
1. The draw. The judge has an envelope of topics. Each speaker draws three, chooses one and returns the other two. 2. The topics. The NSDA manual says topics include proverbs, abstract words, events, quotations and famous people. Each round uses a different subject area. 3. Seven minutes for everything. The speaker has seven minutes to prepare and speak, with a 30-second grace period. A speaker who goes past the grace period cannot be ranked first in the round. 4. No notes. The speech is delivered without notes. 5. The other speakers wait outside. Once the first speaker is called, the rest leave the room until it is their turn. After a student has spoken, they may stay and listen.
At the NSDA National Tournament, the 2024-25 manual lists Impromptu among the supplemental events.
How to Split the Seven Minutes
The NSDA sets no minimum for prep and no minimum for speaking. Its judging guide says a student may divide the seven minutes however they see fit, and it gives two examples: three minutes of prep with a four-minute speech, or one minute of prep with a six-minute speech.
The same guide warns about both extremes. A long speech with unclear ideas hurts the performance, and a very short speech leaves too little time to analyze the prompt. In our experience, beginners do best when they pick a prep time before the tournament and practice to that number every time.
What Judges Look For
The NSDA's guide tells judges to weigh three criteria.
1. Organization. Is there a clear structure, with transitions between the parts? 2. Analysis. Does the student directly address the prompt, justify their ideas and explain why the points matter? 3. Delivery. Does the student use voice, movement and expression well, with steady eye contact and enough volume?
The guide describes the expected shape as an introduction, a body and a conclusion, with the conclusion returning to the prompt and the main points.
The Mistakes First-Time Speakers Make
Talking about the topic without answering it. A student who draws a quotation and then tells three loosely related stories has skipped the analysis judges are scoring. The speech needs one clear claim about what the quotation means or whether it is true.
Spending the prep on the perfect opening. Prep time is short. A student who polishes the first sentence and walks up without two main points will run out of things to say in the body.
Picking the topic that sounds impressive. In our experience, the better choice is the topic your teen already has examples for.
How You Can Help at Home
1. Make a topic jar. Write proverbs, single abstract words, quotations and names of famous people on slips of paper. Have your teen draw three and choose one, just as they will in a round. 2. Run the full seven minutes on one clock. Start the timer at the draw and stop it when the speech ends. 3. Ask for the claim in one sentence. Before they speak, ask "What is your point about this topic?" If they cannot say it in a sentence, they need more prep or a different topic. 4. Build an example bank. Keep a running list of books, historical events, people and personal stories your teen knows well. The same example can serve very different prompts. 5. Listen for the three parts. After each speech, tell them whether you heard an introduction, a body and a conclusion.
How TalkMaze Fits
TalkMaze offers 1-on-1 online public speaking and debate coaching for students ages 5 to 17. Impromptu rewards repetition with feedback, and that is hard to get alone. In weekly sessions, a coach can run draw after draw, rework a weak outline on the spot, and score each speech on the same three criteria a judge uses. Founder Ghalia Aamer is a national debate competitor, TEDx speaker and Princess Diana Award recipient, and every TalkMaze coach trains on the method she built for organizing an idea fast and delivering it with confidence. If your teen likes limited-prep events, read our guide to Extemporaneous Speaking, where the topics are current events and the prep time is longer. If nerves are the bigger worry, see how to help your child stop going blank.
