In this paper, we discuss a variety of spelling tests that are used to assess developmental spelling difficulties. We differentiate between tests that are valuable tools to monitor spelling development and spelling tests that should be used to further assess children who are not making sufficient progress in the mainstream classroom. We recommend the use of several tests in order to achieve these assessment goals. This paper is a practical guide for clinicians and teachers concerned with the assessment (and treatment) of poor spellers. (Contains 3 tables, 1 figure and 14 notes.)
