This is a three tiered system I introduced when leading a learning support team. It is a way of holding TAs/LSAs to account for the progress they make with their interventions with individuals and groups.
Tier 1 sets out the context of the class/group the TA will be working with
Tier 2 is a collaborative document the TA completes in consultation with the class teacher to pinpoint the support
Tier 3 is an outcomes document recording both qualitative and quantitive impact over time
These documents were used as part of QA for Learning Support and to inform performance management and enable TAs to build their own professional portfolios.
The system was praised by both OFSTED and MAT.
