This paper attempts to demonstrate the differences in writing between International English Language Testing System (IELTS) bands 6.0, 6.5 and 7.0. An analysis of exemplars provided from the IELTS test makers reveals that IELTS 6.0, 6.5 and 7.0 writers can make a minimum of 206 errors, 96 errors and 35 errors per 1000 words. The following section explores the differences in error patterns between IELTS 6.0, 6.5 and 7.0 writers and a proposition is made that the IELTS 7.0 writer shows some convergence of error types found among native English writers. In regard to workload issues, the paper discusses the impact of errors as a distraction which affects reading time and gives an indication of the amount of extra workload that may be required to assess IELTS 6.0, 6.5 and 7.0 writing. The paper concludes with remarks about entrance requirements for tertiary study and suggests that it may be simpler to raise entry standards than attempt to remediate the writing of students with low IELTS scores.
