As a school-based SLP I often hear the following questions:
"Should I be worried that Johnny can't _____?"
"Will you come listen to Susie?"
"I just have no idea what is 'normal'!"
Because of this I developed a simple checklist for teacher to have as a reference for what is developmentally appropriate for their students. I wanted the checklist to be quick and simple. I currently have checklists developed for pre-k, kindergarten, 1st, and 2nd grade.
