Language Samples are an essential component of a preschooler’s ongoing assessment in the therapy room and in the classroom. It requires the therapist to assess all aspects of communication, not just the child’s goals or MLU. (Sometimes we use the term MLU lightly and we are quickly looking at an estimated sentence length.) Highlighting the morphemes before counting all the words can be helpful. This checklist includes FORM, CONTENT & USE OF LANGUAGE. When this information is included in a report, it provides the reader with a more comprehensive understanding of the child’s abilities.
