ACS Athens is a co-educational, English-medium day school in Halandri. Its single campus covers Pre-Junior Kindergarten, Junior Kindergarten, Kindergarten, Elementary, Middle School and the Grade 9–12 Academy.

The American route is the school’s foundation. The IB is an option in the final two years, not a curriculum running through the whole school. The IB record authorises only the Diploma Programme and dates that authorisation to 1 January 1976.

MSA-CESS awarded ACS Athens seven years of accreditation in spring 2022. That supports the school’s published end date of 2029.

Who is likely to fit

ACS is a strong option for a family seeking an American school calendar, an American High School Diploma and a possible IB finish. It also suits mobile families who can meet the school’s English and curriculum-entry rules.

It is a poor fit when a child needs boarding, extensive learning-support provision or preparation for the Greek Panhellenic examinations. It is also usually closed to pupils transferring from a Greece-based school after Grade 8.

The campus is at 129 Aghias Paraskevis Avenue and Kazantzaki Street, 15234 Halandri. There is no boarding house and no school guardian service.

Admissions and the 2027 entry routes

The school has not published absolute dates for 2027–28. Its current rules distinguish a local applicant from an international applicant arriving from abroad.

Early Childhood covers ages three and four. Kindergarten is for age five, and Grade 1 is for children aged six by December. The FAQ’s separate September cut-off for age three is impossible as written.

  • Local applicants may apply for first-semester entry from Junior Kindergarten through Grade 5 by the third week of September.
  • Local applicants may apply for second-semester entry to Grades 6–8 by the end of January.
  • ACS does not accept local applications to Grades 9–12.
  • International applicants from abroad may apply to Junior Kindergarten–Grade 5 throughout the year, subject to space.
  • International applicants from abroad may apply to Grades 6–11 until the end of the third quarter, subject to space.
  • Grade 12 entry is limited to applicants from an American-curriculum school.

A Grade 10 applicant must already attend an American-curriculum school. Grade 11 is normally the last entry point because ACS requires two years in an American education system for its diploma.

The school gives priority to continuing pupils, returning pupils and children of alumni. It then considers academic fit, English, the previous programme and capacity. Priority is not an offer.

The online application costs €100 for the first child and €50 for each additional child. These charges are non-refundable, and the school does not process the file before payment.

Applicants submit identification, recent reports and any relevant learning plan or psychoeducational report. Grades 9–12 also need transcripts. The school requests one teacher reference for younger pupils and two for Grades 6–12.

Grades 6–12 take English and mathematics admission tests. Younger children have a developmental, cognitive, English and mathematics assessment appropriate to age.

Do not arrive without an appointment. The school does not allow walk-in admissions visits. A meeting request opens a conversation; it is not an application.

English and Greek requirements

Classroom teaching is in English, apart from Greek and other language classes. The published minimum admission levels rise sharply after Elementary:

Entry grade Minimum published English level
Grades 6–7 A2
Grades 8–9 B1
Grade 10 B2
Grades 11–12 C1

The school may consider a child with little or no English only through Grade 5. It offers English as a foreign or second language (EFL/ESL) support across its divisions. The current Academy course list places formal ESL courses in Grades 9–10.

English support does not override the entry thresholds. For a later arrival, ask which timetable support is actually available before paying the application charge.

All high-school pupils must complete four Greek-language credits for Ministry requirements. Courses include Greek for first-language and additional-language learners.

Greek citizens entering Junior Kindergarten through Grade 9 need Ministry approval before registration. The school’s current page describes qualifying cases, such as dual citizenship, a foreign parent or prior international-school study.

The application follows an ACS offer and needs translated supporting documents. This is a legal registration step, not an informal exemption based only on a surname.

The leaving qualifications

Every graduate must meet the American High School Diploma requirements. The current programme specifies 26 Carnegie credits, including four Greek credits. These credits record completed secondary-school coursework.

Transfer credits are assessed individually. A student joining late should obtain a written graduation audit before accepting, especially if the previous system does not use Carnegie credits.

The IB Diploma Programme runs in Grades 11–12. It includes six subject groups and the IB core. Pupils may instead take individual IB courses and receive course results.

A new external IB applicant must come from abroad from an American or English-language international school. That eligibility rule is separate from the academic thresholds applied to current Grade 10 pupils.

ACS applies its own Grade 10 entry standards for the Diploma Programme. These include C+ in English and history, with B- in relevant higher-level mathematics or sciences. Serious discipline or academic-integrity concerns may prevent entry.

Admission can be conditional. A course also needs at least 12 pupils to run. Continuing to the second year requires 24 points and further subject, conduct and Extended Essay conditions.

The optional Greek-equivalency programme adds six weekly hours of Greek language, literature and history. Two hours are taught face to face after school, with the remainder online.

ACS issues an attendance certificate and transcript for that programme. The family submits those records with the American or IB diploma, and the Greek Ministry decides whether to issue equivalency.

That route is not preparation for the Panhellenic examinations. A family considering Greek public university should obtain specialist guidance before selecting Grade 11 courses.

Tuition for 2026–27

The school’s current table separates tuition from other charges. Its published totals already include the textbook, technology and capital charges shown below.

Grade band Tuition Textbooks Technology Capital Published total
Pre-Junior–Junior Kindergarten €7,332 €90 €71 €297 €9,050
Kindergarten €9,675 €90 €71 €297 €11,393
Grades 1–5 €12,285 €90 €71 €297 €13,782
Grades 6–8 €13,348 €143 €71 €297 €14,898
Grades 9–12 €14,680 €261 €71 €297 €16,348

Each published total also includes €341 institutional tuition per family and a €698 special-project assessment per family. The table repeats both amounts in every grade row, although they are family charges.

The Pre-Junior–Junior Kindergarten and Kindergarten totals include a €221 registration instalment. A family with several children should request one consolidated invoice rather than adding the published row totals.

The two tuition dates are 26 August 2026 and 8 January 2027. The first-semester amount is larger because most annual fees are collected then.

Registration and optional services

The registration charge depends on the entry grade. A Junior Kindergarten entrant pays €221, another €221 in Kindergarten and €522 in Grade 1. Those published instalments add up to €964.

A child entering Kindergarten pays €221 then and €742 in Grade 1. A new entrant in Grades 1–12 pays €963 at entry.

The Pre-Junior–Junior Kindergarten extension to 15:45 costs €1,846 a year, or €923 per semester. The current fee page does not price an equivalent extension for other grades.

Published annual support charges are:

  • English-language support: €1,576.
  • Standard Optimal Learning Programme (OLP): €2,386.
  • OLP consultation: €595.
  • The service labelled ISP in the fee schedule: €238. Ask which individual support arrangements this covers.

A family negotiates the fee for an individual classroom support teacher, described by ACS as a shadow teacher, directly with that teacher.

The school lists €1,400 for the two-year full IB Diploma and €226 for up to four IB courses. More than four courses cost €452.

The fee page says the €1,400 is paid once with first-semester tuition. The Programme of Studies calls it a two-year flat fee but also says payment is due at the beginning of each year.

The current Programme of Studies also estimates about €1,000 for IB exam registration in November of Year 2. That appears separate from the school’s programme charge.

The Greek-equivalency programme is listed at €1,627, split into €813.50 in Grade 11 and €813.50 in Grade 12. The page nevertheless calls it an annual charge, so obtain written billing terms.

Meals are optional. The cafeteria page still displays €5.00 for an Elementary hot meal and €5.50 for Middle or High School, but it also carries a 2025 transition notice.

Treat those meal prices as needing confirmation. Middle School and Academy pupils need PE kit, but the public uniform price page remains labelled 2024–25.

Payment and withdrawal liability

Registration, capital, technology and institutional family charges are non-refundable. A mid-year entrant pays the whole entry quarter, even when attending only part of it, plus every later quarter.

On withdrawal, tuition remains due for the quarter in which the pupil leaves. Later quarters are refundable. Special services, preschool, textbooks and IB fees follow the same quarter rule.

Learning support and accessibility

The Optimal Learning Programme is designed for mild learning differences and does not modify the curriculum. Services depend on the Child Study Team’s decision, available staff and the pupil’s subjects.

Applicants must disclose support history. ACS can require a full psychoeducational assessment, and the FAQ says submitted testing should be no more than three years old.

The eligibility policy allows the school to decline applicants with moderate or advanced cognitive or developmental needs. It also refers to psychiatric disorders as a possible reason for refusal.

The fee table proves that support services exist; it does not prove that a place is available. The old 2020–21 capacity notice remains online, so request a current written decision for the individual child.

The facilities page lists classrooms, laboratories, sports areas, libraries and a theatre. It does not provide a current access audit, lift map or route for a pupil with reduced mobility.

Visit the actual classrooms and toilets your child would use. Ask for a written accessibility plan before paying non-refundable charges.

Transport and daily practicalities

Parents contract directly with the independent bus operator. The 2026–27 annual prices include 13% VAT: Zone A €1,485, Zone B €1,945 and Zone C €2,190.

The contract runs to 18 June 2027 and is paid in two instalments. A declared one-way service for Grades 1–12 costs 65% of the zone price.

Preschool service ending with a 13:00 parent pickup costs 50%. Two addresses cost 100% of the higher zone plus 50% of the second seat.

The service is not door to door. Final stops may take about two weeks after the school year starts, and the operator uses the nearest workable central stop.

There is no refund when a pupil leaves or is ill while the route operates. Serious or repeated misconduct can also end bus access without a refund.

The contract makes parents liable for extra driver, monitor, fuel or toll costs if nobody collects a younger child. The pupil may be returned to school and supervised by security staff.

Scholarship and residence

The only current school-funded award published publicly is the Christos M. Perakis Academic Scholarship for 2026–27. It is for a Greek citizen in Grades 9–12 transferring from a Greek school.

Candidates need admission first, strong grades, fluent English, leadership, financial need and plans for specified overseas fields. The award covers tuition only and is reviewed annually.

That scholarship description conflicts with the general ban on local Grade 9–12 applications. A potential candidate should obtain written confirmation that the scholarship route is an exception.

No amount, 2027–28 deadline or broader financial-aid scheme is published. Do not budget for assistance without a written award.

ACS says it can issue an acceptance letter after admission, but it does not provide a primary or secondary student-visa route. Families should confirm residence requirements with the relevant Greek consulate.

Greek law protects access to compulsory education for third-country minors, including some without regularised residence. That access rule does not itself create permission to live in Greece.

Because ACS is day-only, the family must arrange lawful residence, housing and daily adult care. An offer should never be treated as a substitute for those arrangements.
