Welcome to iTutor Learning Systems
iTutor Learning Systems have been tried and tested by educators and over 100,000 families for over
20 years. Australian owned, we aspire to change the lives of families for the better by making
education more motivating, interesting and effective, no matter what your educational level,
background, or where you live.
We’re passionate about educating children and understand that parenting can be filled with
challenges. Finding the time to sit with each child individually to go over their school work can be a
difficult task when balancing competing schedules and busy family life.
Our Learning System is a professional education software package, complimented by a Tutor Support
Centre and Parents APP. Our programs are tailored to support children’s learning, boost confidence,
self-esteem and empower both the child and parent. iTutor Learning systems is great for children
struggling to keep up in the classroom, as well as being the ideal tool for more talented students
seeking added extension work.
The results really speak for themselves
