Speech Pathology Australia: Speech Pathology in Schools Project

The following evidence will be valuable to speech
pathologists when performing an advocacy
role in schools to highlight the need for speech
pathology in the education sector.
• Australian estimates (from the Longitudinal
Study of Australian Children) indicate that
between 22.3 and 24.5 per cent of children
have a speech, language or communication
disorder at school entry McLeod & Harrison,
2009).
• One large study based on NSW students
estimated that 11 per cent of students in
secondary school have a communication
disorder (McLeod & McKinnon, 2010). There
is no evidence to indicate that the prevalence
of communication disorders in secondary
school students would be significantly
different from this in other states and
territories.
• Forty six percent of young offenders have a
language impairment (Snow, 2014).
• There is very good evidence to indicate a
negative trajectory for these young people
with increased incidence of disengagement
from school, poor educational outcomes,
mental ill-health, problematic behaviour,
anti-social problems and interaction
with the juvenile justice system (Conti-
Ramsden,Durking, Simkin, & Knox, 2009).
• Over 17 per cent of children start school
with scores of “developmentally at risk” or
“vulnerable” in the language and cognitive
domain (which includes pre-literacy skills),
and over 25 per cent are at risk or vulnerable
in relation to their communication skills and
general knowledge as measured by the
Australian Early Development Census at
school entry.
• Children living in the most socioeconomically
disadvantaged locations were four times as
likely to be developmentally vulnerable (falling
below the 10th percentile) than those from
the least disadvantaged areas in the language
and cognitive skills domain (AECD, 2015).
• Children living in very remote Australia
were nearly five times more likely to be
developmentally vulnerable in the language
and cognitive skills domain than children
living in major cities (AECD, 2015).
• Boys were 1.7 times more likely to be
developmentally vulnerable than girls in the
language and cognitive skills domain (AECD,
2015).
• Speech, language and communication
difficulties are closely linked to behaviour
(Lindsay & Dockrell, 2012), social skills, self-
esteem, health and well-being, family and
social relationships.
• Adolescents with speech, language and
communication difficulties have been
shown to be at a greater risk of developing
emotional, social and behavioural difficulties,
mental health issues (anxiety and depression),
emotional difficulties
2,
early school leaving
and poor school engagement.
• There is strong evidence that many students
with language and learning difficulties
struggle enormously with the transition to
secondary school and may develop mental
health problems.

Speech, language and communication needs (SLCN) is the umbrella term most commonly used to describe these
difficulties.

There is now substantial research evidence that children and young people with speech, language and
communication needs (SLCN) are more likely to develop behavioural, emotional and social difficulties (BESD) than
typically developing young people (Beitchman et al., 1996 Fujiki, Brinton, & Clarke, 2003; Tomblin et al., 2000.
Studies have shown prevalence rates as high as 35–50 per cent.

Communication disorders frequently co-occur with mental health issues. Bryan and Roach (2001) reported the
incidence of speech and language problems in individuals receiving mental health services to be higher than that
in the general population. Longitudinal studies have indicated an increased likelihood of mental health problems in
those who initially presented with significant speech/language impairments as a child. Developmental Language
Disorders have been found to contribute to the development pf personality disorders in adulthood.
