Curriculum labels tell you far more than which textbooks a school uses. They shape lesson planning, assessment, classroom language, reporting, and the evidence you will be expected to discuss in an interview. For teachers moving into international education, understanding those differences makes it easier to identify suitable vacancies and explain how previous experience transfers.
No system is automatically better. The right fit depends on how you teach, the age group and subject, and whether you prefer a tightly defined syllabus or greater freedom in how learning is organized.
The International Baccalaureate is a framework built around inquiry, reflection and international-mindedness. British schools usually follow a subject-based progression connected to the English National Curriculum, IGCSEs and A Levels. American schools typically organize learning around grade-level standards, credits and continuous assessment, although the exact model varies by state and school.
Many international schools blend systems. A school may use an American elementary curriculum, Cambridge IGCSE courses in secondary school and the IB Diploma Programme in the final two years. Always investigate the exact campus and division rather than relying on the school name alone. You can compare international-school profiles on Global School Scout before applying.
IB programmes include the Primary Years Programme, Middle Years Programme, Diploma Programme and Career-related Programme. Across them, teachers are expected to connect subject knowledge with inquiry, concepts, reflection and real-world contexts.
Collaboration is central. PYP teachers often plan interdisciplinary units together. MYP teachers work with subject-group objectives, criteria and approaches to learning. Diploma teachers have detailed subject guides, internal assessments and externally assessed components. Schools may expect documented unit plans, moderation meetings and regular reflection on what worked.
Prior IB experience helps, especially for Diploma subjects, but it is not always mandatory. Strong candidates can explain how they encourage student questions, teach transferable skills, assess against clear criteria and collaborate across departments. If you are new to IB, learn the vocabulary without pretending to have experience you do not possess.
British international schools usually work through Key Stages, leading toward GCSE or IGCSE examinations and then A Levels. Subject knowledge, curriculum sequencing and preparation for external exams often carry significant weight.
Teachers normally work from schemes of work that map content and skills across a term or year. Lessons still allow creativity, but there is usually a visible progression toward defined outcomes. In examination classes, teachers must understand specifications, mark schemes, command words and past-paper practice.
Schools value familiarity with Key Stages, safeguarding, differentiation and assessment terminology. For secondary roles, experience teaching GCSE, IGCSE or A Level can be a major advantage. Teachers from other systems should translate their experience into comparable age groups, courses and assessment responsibilities.
American schools are less uniform because standards and graduation requirements can differ. Many use Common Core standards for English and mathematics, Next Generation Science Standards, Advanced Placement courses or school-designed frameworks. High school programmes are often organized around credits, grade-point averages and elective choice.
Teachers commonly use standards-based objectives, unit assessments, projects, quizzes and participation across the semester. Continuous assessment usually matters more than a single external examination. Schools may also expect teachers to contribute to advisory programmes, clubs, athletics or other parts of campus life.
Hiring teams often ask about standards alignment, differentiation, data-informed instruction and classroom culture. AP experience is valuable for relevant high school subjects, but teachers should confirm whether a school uses AP, the IB Diploma, or its own advanced courses.
IB assessment emphasizes published criteria, inquiry and application. British programmes place greater emphasis on externally examined subject mastery in the later years. American programmes generally combine assignments and assessments over time, with policies set at the school or district level.
These are tendencies, not guarantees. A strong international school may combine direct instruction, projects, discussion and examination preparation regardless of its label. Ask how much planning is shared, how student work is moderated, which assessments are external and how teachers report progress.
Your CV should name the curriculum, grade levels, subjects and major assessments wherever possible. Our international teacher CV guide explains how to make that experience clear.
IB may suit teachers who enjoy inquiry, reflection and collaborative planning. A British school may fit teachers who prefer clear subject progression and examination goals. An American programme may appeal to teachers who value continuous assessment, electives and broader participation in school life.
The better question is not which label sounds most prestigious. It is whether the school implements its chosen curriculum well, gives teachers enough planning support and hires you for work that matches your strengths.
