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
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.
