Evaluate the speaker's poise and confidence. The speaker you are grading should communicate ease and comfort in public speaking, despite any nerves. A nervous speaker is distracting to watch and should receive a lower score.
Watch for the speaker to connect with the audience through eye contact. She should have clear enunciation and good speech volume. A successful speaker will grasp and hold on to the audience's attention while a mediocre speaker makes little effort to connect with the audience.
Listen to the clarity of the speaker's message. She should have an introduction that lays the basis for her speech, a well-planned body and a conclusion that ties up any loose ends.
Pay attention to the visual aids the speaker uses. She should use visual aids that are easy to see and understand; that add information to the presentation and do not distract. Average or poor speakers might use visual aids that just add clutter and distraction to the speech.
