Intervention & Extension

At Chelsea Primary School, we have an extensive intervention and extension program from foundation through to year 6 consisting of a number of teachers. We use the Chelsea Primary School Intervention and Extension Model to guide our teaching strategies for the learning of each individual student.

We take pride in ensuring children are engaged and challenged in their learning. Teachers are consistently assessing and analysing data to identify each students’ tier of intervention or extension, to ensure that students can achieve our guaranteed and viable curriculum.

The teaching strategies utilised by our teachers and the tasks they are completing are at a point in the curriculum that will engage and challenge every student, every day.


Students work in small groups with an Intervention and Extension teacher, who explicitly teach our students with point of need instruction, starting from decoding phonemes of the English language, to understanding increasingly complex texts.

Our intervention program in English focusses on improving students reading decoding and encoding skills through the Oroton-Gillingham Multi-Sensory Learning approach. Our extension program in English focuses on improving reading comprehension skills through reciprocal reading, guided reading groups and novel studies.




Students work in an environment that prioritises small student to teacher ratios and explicit teaching, to ensure that students can apply their mathematical learning to real life problems.

Students are encouraged to apply number concepts to measurement, chance and probability scenarios to strengthen their breadth of mathematical understanding.

The Maths intervention program focuses on pre- learning for students who require tier 1 intervention. These students take part in small group sessions where they practice strategies and skills required to succeed, prior to each unit of our whole school mathematics approach.

The Maths extension program focuses on the application and problem solving of mathematical concepts across curriculum areas.
