Introduction

Ionios School is located in Marousi, Greece, and delivers an international education through its diverse curricular offering. From PRE-IB for A' Lyceum, taught in English, to the International Baccalaureate Diploma Programme for Grades 11–12, most classes are conducted in English and structured to develop inquiry, critical thinking, and global awareness. The school also offers German, British, French, Chinese National, Indian curricula, Cambridge IGCSE and Cambridge Secondary in tailored tracks, providing flexibility for international families. A distinctive feature is the Ionios Music Department's own purpose-built studio, the first Greek IB World School to achieve this, alongside purpose-built science and computing laboratories. The Marousi campus houses modern libraries, specialized laboratories, an indoor athletic center, and access to swimming at the nearby Olympic complex. Beyond academics, MUN and Model European Parliament participation, CAS projects, and a wide range of after‑school clubs reinforce study skills, leadership, and community involvement for preparation for top universities.

Wellbeing

Social and Emotional Learning (SEL)
Ionios School's kindergarten aims to help very young children develop physically, intellectually, emotionally and socially. A school psychologist is available to provide guidance when needed and to advise parents and teachers at the beginning of a child's education. The psychologist's role includes counseling on emotional development, behaviour and learning difficulties, working with families and educators to support the child. The school emphasises a collaborative parent partnership with regular communication between the school and families. Teachers receive regular professional development on mental health topics through seminars led by the school psychologist, three times a year.

English as an Additional Language (EAL)
English is taught as part of the morning programme with daily lessons from 1st to 6th grade. Most classes are taught in English, with English as the language of instruction for the majority of subjects; language subjects are taught separately. A second foreign language is introduced in 4th grade (French or German). The school offers English, French, German and Spanish as foreign languages, while Greek language is part of the Greek national curriculum. In the International Baccalaureate Diploma Programme, all classes except language subjects are taught in English.

Mental Wellbeing
A school psychologist provides counseling and guidance to children, parents and teachers on emotional development, behaviour and learning difficulties. The psychologist works with students as a whole, in collaboration with families and educators. The school conducts three annual teacher seminars on mental health topics under the supervision of the school psychologist. The psychologist also supports mental health awareness and education across the school.

Safeguarding
The safeguarding framework covers the safety of children in the school environment, building safety and health protocols. A Mechanical Engineer monitors the buildings, safety systems and outdoor spaces to ensure safe operation. A doctor visits classrooms to liaise with teachers and administration and to ensure hygienic conditions; first aid spaces and a trained nurse provide on-site medical care. Absences must be reported by telephone in the morning to enable effective attendance monitoring and to follow public-health guidance for contagious illnesses. When transporting students, a defined bus pickup/drop-off point is agreed with families, and hospital ambulance support is available for emergencies during activities.
