The Grammar Junior School, previously The Private English Junior School, was founded in 1970 by Ioannis and Iro Gregoriou, following the successful establishment of Cyprus College in 1961 and the Grammar School in 1963.

Their legacy in the education of young children is still continuing with remarkable success by their children Akis Gregoriou, Director General and Sylvana Elefetheriadou Director of the Grammar Junior School.

The School was situated in Agios Dhometios, Nicosia in the 1970s in a building with a few rooms and a much smaller number of children and staff.

The Grammar Junior School has been operating on its present premises since 1981. Significant changes have occurred since then. It has grown in the number of children and staff and the buildings and facilities have been impressively upgraded.
