The three tiers of support are generally described as universal (Tier 1), targeted (Tier 2) and individualised (Tier 3). The model is designed to be dynamic and integrated, rather than a linear progression from one tier to the next. This means support can be tailored to the needs of each mokopuna and the context. Supports and interventions can be used from any of the three tiers at any time (alone or in combination). Generally, however, universal approaches will be the first step in responding to the diverse needs of mokopuna
Decisions about which supports and interventions to use are based on data gathered about the needs and progress of the mokopuna. Data will continually be reviewed and modified to reflect changing needs and the progress made.
