Spelling assessment activities are described, including lists of questions designed to investigate auditory skills, tactile skills, and visual skills. Also considered is assessment of punctuation, capitalization, syntax, organization, and ideation. Remediation activities are proposed for spelling errors caused by auditory and visual deficits, as well as errors in punctuation, capitalization, written syntax, organization, and ideation.
