The impact of poor spoken language

Children with poor language skills struggle across many areas. The impact of having poor spoken language affects educational outcomes, social relationships, employability and places young people at risk of poor mental health and offending.


“Good communication is one of the most important skills anyone could have.”

“We need communication skills to get jobs, interviews, for later life.”

“If you have good communication skills, socially it gives you more confidence.”

“We need communication skills to control things and get things done.”

“You need to be able to communicate to get what you want... in a good way.”

“If you can’t express your views then you don’t get listened to.”
