Language Development
Language develops at different paces for every child. Here are the stages of language development and typical age ranges each child should reach for each milestone.
Intelligibility
What is intelligibility? It is the ability for others to understand what the child is saying. The child's speech may not be in full sentences or grammatically correct, but the message is successfully communicated and understood by others. A child's speech intelligibility rate may vary depending on the listener's relation to the child (i.e., caregivers, siblings, relatives, peers, teachers, SLPs, strangers) as well as the age and developmental stage of the child.
