I currently use this debate speech rubric when I am assessing my students on a debate speech. Please note that it does not incorporate the assessment of oral speaking. You may choose to also assess a student's oral speaking below the rubric.
I have used this particular rubric in units of study such as: To Kill A Mockingbird, April Raintree, The Hunger Games, Animal Farm, Flowers for Algernon, Of Mice and Men, The Diary of Anne Frank, 1984, and many others.
This outcome-based rubric has been included on my site for free.
