IGCSE and home education have gone together for years, and for a practical reason rather than a snobbish one. The difference that matters most to a home educator is how the exam boards check practical and spoken work, and that is exactly the part a home-educated student cannot easily do. This guide sets out the real differences so you can choose subject by subject.
What is the difference between IGCSE and GCSE for home education?
The difference between IGCSE and GCSE that matters for home education is assessment, not content: IGCSEs are designed for students worldwide and are almost entirely assessed by written exam, while GCSEs in England include components a centre must run or confirm in some subjects. Education Otherwise’s FAQ factsheet puts it plainly: many home educating parents choose IGCSE “as these examinations are considerably less likely to involve a coursework element”.
Both are Level 2 qualifications graded 9 to 1 (Pearson, and Cambridge’s 9 to 1 variants) or A* to G (Cambridge’s original syllabuses). Both are sat as a private candidate through a centre under JCQ rules, as described in our guide to how home-educated students sit GCSEs. The regulatory status differs, and that is covered below.
Which exam boards offer IGCSE in the UK?
Two exam boards offer IGCSEs that UK private candidates can sit: Pearson Edexcel, whose qualifications are called International GCSEs, and Cambridge International, whose qualifications are called Cambridge IGCSEs. Education Otherwise’s factsheet names the same two boards, and the JCQ’s private candidate centre search lets you filter for Cambridge IGCSE and Pearson Edexcel IGCSE.
The two boards are not interchangeable. Specification codes, paper structures and grading scales differ, and a centre may accept one and not the other. Pearson’s International GCSE Biology is 4BI1; Cambridge IGCSE Biology is 0610 (A* to G) or 0970 (9 to 1). Decide the board before you buy a textbook or book a tutor, because everything downstream follows from it.
Why do home educators choose IGCSE for science?
Home educators choose IGCSE for science because its practical skills are examined on paper, while GCSE science requires the entering centre to confirm that set practical activities have been completed. For a student working at home, that confirmation is the hard part.
The GCSE rule comes from Ofqual. Its conditions for GCSE Biology, Chemistry and Physics require every student to complete at least eight set practical activities and require the centre to provide the board with a “practical science statement” confirming this; at least 15% of the exam marks test practical knowledge. AQA’s condition for private candidates in Biology, Chemistry, Physics and Combined Science is that “the entering centre must make provision for private candidates to carry out all the practical activities” in the specification. Some centres will do this. Others, such as Tutors & Exams, list GCSE sciences for private candidates only where the student is “carrying forward practicals” from a previous centre.
The IGCSE position is written into the specifications. Pearson’s International GCSE Biology specification states that practical investigations are included as specification points and that “experimental skills are assessed through written examinations”. Cambridge IGCSE Biology 0610 gives a choice between Paper 5, a practical test in a laboratory, and Paper 6, Alternative to Practical, for which “candidates will not be required to do experiments as part of this test”; the two papers test the same skills and the same assessment objective.
One caution. Examined practical skills still have to be learned by doing. Your child needs to have used a measuring cylinder, drawn a results table, plotted a graph with a line of best fit and explained why a result was anomalous. Kitchen-bench versions of the standard experiments cover most of this. A tutor who knows the required practicals can set them up for you, which our guide to choosing a home education tutor discusses.
Which IGCSE subjects are available to private candidates?
Most IGCSE subjects are available to private candidates, but a few syllabuses or options are not, and the only reliable check is the specification itself plus the centre. Cambridge International says that “some syllabuses or options are not available to private candidates” and that the details are in each syllabus document; the 0610 Biology syllabus, for example, states that private candidates can enter.
Pearson publishes a list of International GCSE subjects with conditions for private candidates. For International GCSE English Language A (4EA1) and B (4EB1) the condition is that the centre “must supervise, authenticate and mark” the spoken language endorsement. The sciences, mathematics and most humanities carry no condition on that list.
English Language is where IGCSE and GCSE differ most after science. Ofqual’s GCSE English Language conditions require a spoken language assessment that is reported separately as Pass, Merit, Distinction or not classified and does not affect the 9 to 1 grade; the entering centre has to run it. Ask any centre, GCSE or IGCSE, exactly how it handles the spoken component before you pay.
Do universities, colleges and employers accept IGCSEs?
UK universities and colleges generally treat IGCSEs as GCSE-level qualifications, and the boards publish the evidence, though individual entry requirements vary. Cambridge International’s UK recognition page states that UK NARIC “carried out an independent benchmarking study of Cambridge IGCSE and found it to be comparable to the standard of UK GCSE”, and that Cambridge IGCSE qualifications “are accepted as equivalent to UK GCSEs by leading universities both in the UK and around the world”.
Pearson’s position is in its 2019 letter to the Education Select Committee: its International GCSE is “developed, designed and benchmarked to be of equivalent standard to our GCSE 9-1 qualification regulated by Ofqual”. The same letter records that “Ofqual does not regulate international GCSEs”, so these are not Ofqual-regulated qualifications, and a DfE analysis notes that international GCSEs “have not counted in school performance tables since the corresponding reformed GCSEs became available, from 2017 onwards”. Neither point affects a home-educated student, who is not in a performance table. The practical advice is simple: where a course or job asks for “GCSE grade 4 in English and maths”, ask the admissions or HR team in writing whether an IGCSE grade 4 satisfies it, and get the answer confirmed for your child’s case.
What does IGCSE cost compared with GCSE?
IGCSE costs slightly more than GCSE at the board level and about the same at the centre level. Pearson’s 2025/26 UK fee list prices an International GCSE at £67.00 per subject against £54.80 for GCSE Biology and £55.00 for GCSE Mathematics, and International GCSE Double Award Science at £134.00 against £103.40 for GCSE Combined Science.
At Tutors & Exams the 2025/26 private candidate price was £272.50 for an IGCSE single science or maths against £261.60 for a GCSE single science and £316.10 for GCSE Maths, so the gap closes once the centre fee is included. Our home education GCSE costs guide has the full table.
How should a home-educating family decide between IGCSE and GCSE?
A home-educating family should decide between IGCSE and GCSE subject by subject, starting from what the available centres will actually enter. Four steps settle it:
- List the subjects your child will take.
- For science, default to IGCSE unless a centre near you confirms in writing that it will run the GCSE practicals for a private candidate. For English, ask how the centre handles the spoken element on either route, because Pearson’s International GCSE English Language A and B also have a spoken endorsement the centre must supervise and mark.
- For maths and the humanities, choose on resources and the centre. Both routes are exam-only in these subjects, so the deciding factors are which board your centre accepts and which textbooks and tutor you can find.
- Confirm each specification code with the centre before buying anything.
A mixed set, IGCSE sciences with GCSE maths and history for instance, is possible because each subject is entered separately, provided the centre accepts each entry; check any college’s specific requirements. Our revision hub covers study methods for both.
