Research & Advocacy

Developmental Language Disorder affects approximately 1 in 14 children and presents as a lifelong disability of language difficulties persisting after entry to school.

The emotional and financial impact to families is considerable. Relative to the impact of the disability, there remains a significant gap between research and practice. The outcomes of specific interventions have not been systematically assessed and measured, which poses a gap in this field of research that needs to be addressed. As the nation’s peak body supporting and advocating for the needs of young people with speech, language and related disorders, Speech & Language Development Australia (SALDA) is well placed to assist in closing that gap.

SALDA continues to demonstrate an ongoing commitment to raising awareness for children and young people with Developmental Language Disorder. Through long term relationships, SALDA has been able to share our vision for Developmental Language Disorder with Local, State and Federal governments. The organisation has also been able to represent the interests of children and young people across various forums, which provide opportunities to educate others on the importance of language development. While many people have not heard of Development Language Disorder, continuing conversations will ultimately lead to increased awareness and positive outcomes.
