The AWA consists of one 30-minute writing task—analysis of an argument. It is important to be able to analyze the reasoning behind a given argument and write a critique of that argument. The essay will be given two independent ratings and these ratings are averaged together to determine the test taker's AWA score. One rating is given by a computerized reading evaluation and another is given by a person at GMAC who will read and score the essay themselves without knowledge of what the computerized score was. The automated essay-scoring engine is an electronic system that evaluates more than 50 structural and linguistic features, including organization of ideas, syntactic variety, and topical analysis. If the two ratings differ by more than one point, another evaluation by an expert reader is required to resolve the discrepancy and determine the final score.[15]

The analytical writing assessment is graded on a scale of 1 (the minimum) to 6 (the maximum) in half-point intervals (a score of zero means the answer was gibberish or obviously not written on the assigned topic or the test taker failed to write anything at all on the AWA).
