A Capacity Matrix is a tool to describe document and monitor our learning. It allows us to clearly identify what is it we wish to learn derived from the curriculum and student interests and then track learning over time. It can be very effectively used with the Plan Do Study Act (PDSA) cycle and supported with a portfolio that provides evidence of our learning. Capacity Matrices are also used for self-assessment as well as peer assessment. An example of a Capacity Matrix for Year 8 Measurement - developed by Yvette Riley and colleagues at Woodville High School in South Australia.
