When should my child have all their sounds?

The American Speech and Hearing Association recommends all sounds be acquired by age 8.

Here is a break down of when each of the sounds should be acquired by age:

age 2-3: /p/ /b/ /m/ /n/ /t/ /d/

age 4: /k/ /g/ /f / /s/ /y/ /h/

age 5: /v/ /z/ /l/ /ch/ /sh/ /j/

age 6-7: /r/ /th/

Personally I like to watch 5 year old children until about mid way through the school year (December) to see if they are acquiring some of their missing sounds. Then if they are not, I prefer to start targeting some of those phonemes they are stimulable for easy correction of in January. Age 8 is second grade when academics pick up and the reading and writing work increases. I’d rather they have their articulation all accurate at that point. So I don’t like to wait that long if I can avoid it.

Sadly, schools are providing less and less articulation therapy in school if that is all a student needs. A teacher has to observe that it is negatively impacting learning, such as spelling or reading and writing, which often it is not. You may have to seek out private therapy for this service.
