Evaluation is a type of speech where the evaluator seeks to provide honest reaction in a constructive manner to the speaker. See Effective Evaluation, item 202. Most Meetings will have an Evaluation portion.
There may be an Evaluation contest as part of a speech contest. In such a case, a Test Speaker delivers a speech which each contestant, after being secluded so as not to hear the other evaluators, evaluates.
