In practice, this solution is far more complex.
Let's start with children. Ideally, every primary school in Australia would build a multi-tiered system of support for literacy. This will ensure all children receive evidence-informed, explicit instruction in foundational literacy skills, such as phonics, the ability to translate letters into sounds to decode written words, and morphology, the ability to use the smallest units of meaning within words to read words.
If a child fails to respond to this instruction, they should receive additional help, in a small group or individually. It is very heartening to see numerous primary schools across Australia starting to build this kind of system to support literacy, but they are still in the minority
This same approach should be used by secondary schools to support teens who struggle with functional literacy. However, it is more difficult to build a multi-tiered system for literacy in secondary schools, which lack the time, expertise and resources to support the large number of incoming students who need this help.
Secondary schools have traditionally been designed to teach subjects such as English or English literature on the assumption students who arrive will already be literate.
