Issue editor foreword: Focus on meta skills: Part 1. Morphological awareness and assessment; Part 2. Autism and concepts of self

The meta skills of metalinguistics (specifically, morphological awareness), metacognition, and metapragmatics are important for school success. Multiple factors appear to influence the development of these skills, which must be considered when developing and interpreting related tasks of assessment. The articles in this issue present interesting concepts and methodology for assessment of a variety of important meta skills with diverse populations of school-age children. Continued consideration of the issues described in each of these articles will serve to inform best practices for assessment of meta skills and may stimulate new directions of investigation.
