Small class sizes increase the time the teacher can spend with each child. More individual attention ensures that each pupil's strengths can be built on and additional learning support offered where needed. Teachers also have more opportunity to use flexible instruction techniques to suit the needs of each individual child.

Small class sizes improve the classroom atmosphere, creating a more responsive environment. A lower level of noise improves class interaction making the children feel more comfortable and confident voicing their questions.

Class sizes at the school vary at differing year levels.  The teacher pupil ratio of 1:16 in Year 1 ensures that each new entrant is closely monitored. A ratio of 1:20 at Year 8, coupled with the extensive use of specialist teachers, prepares the children for a smooth transition to secondary school. (To put this into perspective - many classes have a quarter to a third fewer pupils per teacher than in many state schools.)

Additional teaching resources are provided to any temporary increase above optimum levels.

Junior School
Teaching ratios are enhanced by the input of specialist support teachers in learning extension and learning support, reading, music, art and physical education classes. The children also benefit from the use of school support resources – including our librarian and chaplain. Extra tuition opportunities, such as ballet, French, karate and sports coaching are also offered.

Girls' and Boys' Prep Schools
At this level, additional specialist teachers are introduced in the core subjects of English and mathematics  for Years 6 – 8, resulting in an average instructional class size of 1:15 or fewer.

Learning extension and learning support
The Cathedral Grammar School offers a strong support infrastructure and learning extension opportunities to ensure that every child receives teaching support appropriate their needs.  Whether your child is academically able and in need of extending, or requires extra help in some topics - we can offer the additional learning support they need.
