IB vs Cambridge curriculum: key differences for a K-12 school

Two different kinds of thing

The IB offers four programmes, the PYP, MYP, DP and CP, that form a continuum for students from about age 3 to 19. Each programme is a framework: it sets the philosophy, the structure and the assessment approach, and the school writes its curriculum inside it.

Cambridge offers a pathway of stages and qualifications: Early Years, Primary, Lower Secondary, then the IGCSE and AS and A Level qualifications. Its curriculum is expressed as syllabuses by subject, with published schemes and assessments attached to the later stages.

That difference, framework versus syllabus, explains most of what follows. The IB and Cambridge each publish the current specification of their own programmes, so treat their documentation as the authority and use this article to frame questions, not to settle facts.

How the IB approaches curriculum

IB programmes are organised around concepts, inquiry and reflection. Depending on the programme, schools work with transdisciplinary themes, key and related concepts, global contexts, objectives and criteria, and the learner profile and approaches to learning that run across all four.

The consequence for a school is that teachers plan units collaboratively and document them, which is a significant and continuing workload. The gain is a coherent whole-school picture and a shared language across subjects.

How Cambridge approaches curriculum

Cambridge is subject-led. A school chooses the subjects it offers, follows the published syllabus and prepares students for the assessments. The Lower Secondary and Primary stages give schools a framework and checkpoint assessments; the IGCSE and A Level are external qualifications with a published syllabus and examinations.

The consequence is a clearer external target and often a more familiar shape to teachers trained in a national system. The planning is syllabus-driven, and the school has more freedom over how each course is taught and how subjects are combined.

What is the difference between IB and Cambridge for a K-12 school?

For a K-12 school the useful comparison is the whole journey. Map which programme applies at each age, how students move between stages, and how the school's educational goals are carried across the years rather than restarted at each transition.

Many schools do not choose one. A common pattern is an IB primary programme, a Cambridge IGCSE in the upper middle years, and then either the IB Diploma or A Levels, and a school that mixes frameworks needs its planning, assessment and reporting to hold together across them.

Where skodle fits

This section names our own product, so read it as that. The comparison above holds whatever software a school runs.

skodle is built for IB, Cambridge and CBSE schools. Its curriculum engine, the IB Engine, is built around the four IB programmes rather than one generic template: PYP and MYP units carry their programme's own fields, and the DP and CP core components are tracked per student. Around it sit the whole-school layers that do not depend on the curriculum: assessment and gradebook, attendance, reporting, portfolios, family communication and school operations, which is why a school running two frameworks can keep one record of a child.

The limit is specific. A Cambridge syllabus or scheme of work is not modelled the way an MYP unit is: curriculum maps, standards and the coverage report are built to the four IB programmes. A Cambridge school, or the Cambridge years of a mixed school, uses the school structure of stages, year groups and subjects, unit planning that can be tagged to its framework, and the shared layers, but not curriculum maps or coverage analysis built to Cambridge syllabuses.

How to compare them for your school

Work through the questions that are specific to you rather than to the curricula in general.

• Philosophy: does your school's stated approach fit a concept-based framework or a subject-led one?
• Staff: what have your teachers been trained in, and what would retraining cost?
• Assessment: which external results do your families and universities value?
• Workload: are you resourced for collaborative unit planning and documentation?
• Pathways: where do your graduates go, and what do those institutions ask for?
• Systems: can your software carry the frameworks you choose, and in what depth?

Common mistakes when choosing

The most common error is choosing by reputation rather than fit. Others are assuming the two are interchangeable and can be swapped later without retraining staff; underestimating the documentation and collaborative planning the IB asks of teachers; treating a qualification as a curriculum, so that a school adopts IGCSE syllabuses and believes it has designed one; and overlooking local recognition.

In some countries, India among them, a school offering an international curriculum may still need its own state or national approvals, which is a separate process from the IB's authorisation or Cambridge's recognition. The Indian route is set out in how to start an IB school in India.

The technology question

A school that runs both often ends up with separate systems that do not talk to each other. Ask any vendor to show a unit and a report from each framework you teach, and to say which are native to the product and which are handled through generic fields. The honest answers differ, and it is better to hear them before migration.
