Early intervention is best conceptualised as a system designed to support 
                  family patterns of interaction that best promote children's development.
                  
                  Guralnick, 2001
'Early intervention' can be taken to mean either:
- action taken early in life
 - action taken early in the onset or at the diagnosis of impairment
 
...the large majority of early intervention activity is initiated during the first three years of life.
                  Shonkoff and Meisels describe the scope of early intervention:
                  
                  ...to promote child health and wellbeing, enhance emerging competencies, 
                  minimize developmental delays, remediate existing or emerging disabilities, 
                  prevent functional deterioration and promote adaptive parenting and overall 
                  family functioning. These goals are accomplished by individualized developmental, 
                  educational and therapeutic services for children provided in conjunction 
                  with mutually planned support for their families.

Early intervention is not just about providing support for disabled children 
                  and their families early in childhood. Disabled children and their families 
                  need properly coordinated support, delivered as soon as they need it, 
                  particularly at key transition points in their lives, and they need services 
                  and support to respond quickly when their circumstances or a child's condition 
                  changes.

Early support...is essential to prevent problems such as deteriorating 
                  health, family stress and breakdown, children potentially being placed 
                  in care, and deteriorating emotional and social development for disabled 
                  children and their siblings.

Early intervention means professionals working in partnership with parents 
                  of children with special needs to help their children develop their knowledge 
                  and skills to reach their potential. It builds upon the strengths found 
                  in all children and families.
                  
                  Research and practice have proven that early intervention produces immediate 
                  and long term benefits for children with disabilities, their families, 
                  and society.

The key goals of early intervention are:
- To support families in supporting their children's development.
 - To promote children's development in key domains (cognitive, social, physical, emotional, linguistic) via early years curriculum and learning opportunities.
 - To promote children's coping confidence.
 - To prevent the emergence of future problems.
 
Wolfendale, 2000
                  An effective early intervention programme should:
- Be based on a child developmental framework.
 - Take a systems perspective, in which all aspects relate and are fully integrated.
 - Be evidence-based.
 - Be personalised.
 - Be child- and family-centred and participative.
 
- Value families and professionals.
 - Work to shared agenda and shared goals.
 - Be proactive in identifying risks and concerns.
 - Be overviewed, monitored and evaluated with opportunities for child/family feedback.
 - Accommodate cultural differences.

early intervention programmes
                  Families value the following features of early intervention programmes:
- A full statutory-voluntary sector mix.
 - Early and sympathetic diagnosis and intervention.
 - A 'whole' family approach in partnership.
 - Simplicity rather than complexity.
 
- Aspirational features of services.
 - Intensive and persistent interventions – as long as excessive demands were not made of carers, especially mothers.
 
Parents valued family-centred services delivered by skilled, knowledgeable 
                  and efficient professionals, especially where key workers were part of the 
                  overall package... [Keyworkers] are associated with better family relationships, 
                  quicker access to financial benefits and reduced parental stress.

into practice
                  Identify the key elements of early intervention, and draw up a plan, including specific actions, of how you could apply them for the families of the children and young people you work with.
