Merton Child and Young Person Well Being Model (MWBM) 2013 has been revised as a 3-band spectrum, replacing the former 5-band spectrum.

Some identifiers for children with additional needs are outlined in Merton MWBM 2013 trio of Tables of Additional Needs Indicators as follows:

The levels indicated are not absolute thresholds - rather a guide to assist in the assessment as to the level of vulnerability and appropriate intervention.

All professionals assessing the needs of children, young people and their families must consider strengths and risks in all three domains of the assessment framework.

Exposure to risk factors is associated with an increased likelihood of experiencing negative outcomes.  The combination or accumulation of risk factors, especially when occurring across more than one domain, results in a much higher probability of a child suffering negative outcomes.

Exposure to protective factors, such as those outlined on chart following, may reduce the likelihood of negative outcomes.

In using their professional judgement, practitioners need always to take into account the context of the situation, as well as such protective and resilience factors. Decisions relating to the type of intervention necessary must be evidence based, using professional judgement, backed up by consultation and supervision.
