Assessing the emergence of grammar in toddlers at risk for specific language impairment

The purpose of this article is to identify areas of grammatical development that can be incorporated into risk-factor assessment models for toddlers between the ages of 2 and 3. A simple framework is presented for conceptualizing three early grammatical accomplishments: the acquisition of an initial verb lexicon, production of early sentence types, and the onset of tense marking. Strategies for using parent-report instruments and structure-specific language sampling to assess these areas in a time-efficient manner are provided.
