Curriculum details	Curriculum details Saint-Charles offers two curriculum pathways: the Swiss Programme and the International Baccalaureate (IB) Programme. The Swiss Programme covers primary through maturité and uses instruction in French, English and German; Primary is taught in English and French, and the Middle School is multilingual in English, French and German. The Swiss Maturité is bilingual French-English and is recognised by the Swiss Confederation, with the school authorised to prepare students for maturité examinations. The IB Programme is taught in English, offering the Middle Years Programme and the Diploma Programme, with English as the language of instruction for all subjects and ESL support available. Immersion language teaching introduces English and German from early years through 'language islands' where other subjects are taught in additional languages, laying the foundation for bilingual Matura or the IB Diploma Programme.	Curriculum details SIS Basel offers an English/German bilingual kindergarten with continuity from Kindergarten to College. The curriculum combines the Swiss curriculum (Lehrplan 21) with the British curriculum and SIS-developed content to promote bilingualism. Children spend 50% of their time in English and 50% in German. The six curriculum areas are Personal and Social Development; Language Development; Mathematics; Knowledge and Understanding of the World; Physical Development; and Creative Development. Language is learned through immersion with a German-speaking and an English-speaking teacher, with languages used on alternating days. The day runs from 7:30 a.m. to 6 p.m., with after-school care and a range of clubs, and regular trips and events form part of the program.

Admissions	Admissions
Admissions	Admissions Three steps are required for enrolment: schedule an appointment with the school headmistress; during an interview, all aspects of the curriculum and admissions are discussed, with the child present. The parents complete the enrolment application and send it to the secretariat and pay the enrolment fee, after which enrolment is confirmed. For primary school, motivation to learn in a multilingual environment is sought; for secondary school, candidates must pass entrance tests in French, Math, and German. Saint-Charles offers two high school streams, one in French and one bilingual French-English, both recognised by Swiss educational authorities. Appointments can be booked online or by contacting the school secretary. The admission process includes providing documents (school reports for the last two years, a letter of recommendation, and a color scan of the passport), an interview and admissions testing, and language assessments (IB Diploma: English Proficiency; Swiss Matura: English and French Proficiency) plus a Maths assessment. The Head of Admissions reviews applications and responds in roughly 10 days. Possible outcomes are admittance with a welcome package and visa procedures; provisional acceptance after a language-study period; waitlist; or non-acceptance.	Admissions 1. Getting in Touch. Contact SIS Basel via the contact form, by email, or by phone. You are welcome to visit an Open House to gain an impression of everyday school life and meet the school leadership. We provide further information and discuss together what the next suitable step might be for you and your child. Open Houses offer an informal setting to ask questions and learn about SIS Basel. 20 2. Consultation. A personal consultation is arranged. During the consultation, we take the time to get to know you and answer questions while introducing you to our school and educational concept. If possible, a tour of the school building is provided to give a brief insight into classroom life; virtual, phone, or email consultations are also available. 20 3. Trial Days. If the consultation is positive for both sides, one or more trial days are arranged to experience everyday school life and assess comfort in the environment. Trial days are non-binding. If trial days are not possible, an alternative solution is discussed. 20 4. Registration. If you decide in favour of SIS after the consultations and trial days, you will be provided with the registration form digitally or in printed form. Complete the form in full and submit it to the SIS school of your choice. We are happy to support you if you have any questions. 20 5. School Contract – Welcome to SIS!. After the registration is received, the school contract is prepared and sent along with information about the enrolment fee.
