Students at this level are able to write about a variety of topics with significant precision and detail. They can handle informal and formal correspondence according to appropriate conventions. They can write summaries and reports of a factual nature. They can also write extensively about topics relating to particular interests and special areas of competence. Advanced writers can narrate and describe in the major time frames, with solid control of aspect. In addition, they are able to demonstrate the ability to handle writing tasks associated with the Superior level, such as developing arguments and constructing hypotheses, but are not able to do this all of the time. They have good control of a range of grammatical structures and a fairly wide general vocabulary. At this level, writers show good control of the most frequently used structures and generic vocabulary, allowing them to be understood by those unaccustomed to the writing of non-natives.
