Fluency is the ability to have an easy flow to conversational speech.
Not sure where to get started??
Start by talking with the SLP/A at your school.
Observe your student, when do they have a tendency to stutter?
Think of ways as a listener that you can make it easier for them in situations where they seem to stutter more.
Let your student talk, it may take awhile for them to get what they are saying out but be patient.
Don't interrupt them or fill in the blanks for them... give them time.
Encourage them to speak their thoughts.
