It’s common for parents to wonder whether their child is ready for Kindergarten, while also feeling excited that their child has reached this new milestone.

At TIGS Prep we build the social, emotional and foundational skills that young learners need in order to thrive when they transition into the Junior School. By harnessing the innate curiosity and creativity of children, our preparatory programme unlocks the power of play-based learning.

Junior School

  • Personalised learning and outstanding academic achievement.
  • Kindergarten to Year 6.

Not every school can provide the level of personalisation, academic focus and support that form part of the core offering at TIGS, but every student requires these to achieve their best.

Our Junior School is a warm and friendly environment where children thrive. When students feel safe and supported, they are empowered to achieve their full potential. Through an environment where care and attention are active, our students are able to flourish academically.

We create a highly personalised experience for each student, using extensive data analysis to understand exactly what they have learned and deliver what they are ready to learn next.
