Writers at the Advanced-High level are able to write about a variety of topics with significant precision and detail. They can handle most social and informal correspondence according to appropriate conventions. They can write summaries, reports, precis, and research papers. They can also write extensively about topics relating to particular interests and special areas of competence, but tend to emphasize the concrete aspects of such topics. Advanced-High writers can describe and narrate in all major time frames, with good control of aspect. In addition, they are able to demonstrate some ability to incorporate the functions and other criteria of the Superior level, showing some ability to develop arguments and construct hypotheses. They cannot, however, sustain those abilities and may have difficulty dealing with a variety of topics in abstract, global, and/or impersonal terms. They often show remarkable ease of expression when writing at the Advanced level, but under the demands of Superior-level writing tasks, patterns of error appear. Although they have good control of a full range of grammatical structures and a fairly wide general vocabulary, they may not use these comfortably and accurately in all cases. (continue to next page)
