Writers at the Advanced High sublevel 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, although their writing tends to emphasize the concrete aspects of such topics. Advanced High 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 cannot produce Superior-level writing consistently across a variety of topics treated abstractly or generally. They have good control of a range of grammatical structures and a fairly wide general vocabulary. When writing at the Advanced level, they often show remarkable ease of expression, but under the demands of Superior-level writing tasks, patterns of error appear. The linguistic limitations of Advanced High writing may occasionally distract the native reader from the message.
