Australian legislation and educational policies may espouse, but not yet fully enact, inclusive assessments for all. In relation to the National Assessment Program for Literacy and Numeracy (NAPLAN), for example, almost 5% of students are either exempt or withdrawn. The achievement levels of these students, many of whom have disabilities, are not being accurately benchmarked. In contrast, the United States, for more than a decade, has been developing and applying a range of strategies in an effort to provide assessment for all students. Lessons from these experiences are summarised, and three key strategies are provided, to assist the Australian Curriculum, Assessment, and Reporting Authority (ACARA) and associated testing authorities in promoting the development and implementation of a more effective and inclusive assessment regime for all Australian students.
