The two qualifications in plain English
The French baccalaureate, since the 2021 reform, is taken across the last two years of upper secondary (Premiere and Terminale) at age 17 to 18. Pupils take a common core (French, history geography, modern languages, scientific education, philosophy, sport) and choose two or three specialism subjects (enseignements de specialite) that they continue to depth. Their final mark combines continuous assessment from Premiere and Terminale, written examinations in the chosen specialisms, the philosophy paper, and an oral examination (the Grand Oral). The qualification is graded out of 20 with 10 the pass, 12 mention assez bien, 14 mention bien and 16 mention tres bien.
The IB Diploma is a two year programme of six subjects (three Higher Level, three Standard Level) with Theory of Knowledge, an Extended Essay of around 4,000 words, and the Creativity, Activity and Service (CAS) portfolio. It is graded out of 45 points. It runs in roughly 5,800 schools across 160 countries, including a small but growing number of Lycees francais a programme international and a few standalone international schools in France.
For the structural detail of each, see our French curriculum guide and IB curriculum guide.
Side by side comparison
| French baccalaureate | IB Diploma | |
|---|---|---|
| Origin | France, regulated by the Ministry of National Education | Switzerland, regulated by the IBO |
| Structure | Common core + 2 to 3 specialism subjects + philosophy + Grand Oral | 6 subjects (3 HL, 3 SL) + TOK + EE + CAS |
| Final grade | 0 to 20, with mentions assez bien (12+), bien (14+), tres bien (16+) | 0 to 45 points |
| Language of instruction | French; OIB and BFI track adds a second language pathway | English, French or Spanish; bilingual diploma available |
| Independent research | None core; Grand Oral assesses an extended question | Compulsory 4,000 word Extended Essay |
| French university entry | Direct access via Parcoursup | Accepted with equivalence; classes preparatoires can be tougher |
| UK university entry | Accepted with specific specialism grades, often mention bien minimum | Widely accepted; typical offer 34 to 40 points |
| US university entry | Accepted but less familiar; AP or SAT usually requested | Widely accepted; sometimes HL credit at 5+ |
| Mobility mid-programme | Limited; specialism choices lock at end of Seconde | Strong, within the IB worldwide network |
| Best for | Families staying in francophone education | Mobile families and those targeting universities outside France |
Rigour and workload
The reformed French bac is more demanding than its predecessor in some respects and less in others. The specialism subjects, taken to depth across two years, sit at a level that French universities accept as preparation for first year work. Philosophy remains a serious written commitment for every pupil regardless of stream. The Grand Oral, introduced in 2021, asks the candidate to defend a question they have developed for themselves: it is closer in spirit to an Oxford interview than to a standard secondary oral. The continuous assessment component (40 per cent of the final mark) means workload is sustained rather than concentrated at the end.
The IB Diploma is demanding in breadth and in academic skills. The Extended Essay is the single best preparation for university-style independent writing that exists in any secondary qualification. Theory of Knowledge teaches pupils to reason about how we know what we know, in a way the French bac does only patchily and only at the philosophy level. The CAS portfolio is administratively heavy. Higher Level subjects sit at depth comparable to bac specialisms.
Neither qualification is academically soft, and neither is meaningfully easier than the other for an able pupil. The honest difference is where the cognitive load sits. The French bac front-loads philosophical and oral confidence in French. The IB front-loads written research and time management in English.

University routes inside and outside France
Inside France, the bac is the legal entry to higher education via the Parcoursup platform. Mention bien or tres bien meaningfully opens access to the more selective parcours, including classes preparatoires aux grandes ecoles. The IB Diploma is accepted by French universities via an equivalence procedure and a baremed conversion, but candidates from the IB route into classes prepa or into the elite Sciences Po and ecoles de commerce face additional scrutiny on subject coverage and on French linguistic competence. For a child committed to a French higher education trajectory, the bac is the smoother road.
UK universities accept the bac fluently. A typical Russell Group offer for a French bac candidate sits at 14 to 16 out of 20 overall with specific specialism subject grades. Oxford and Cambridge usually want 16 or 17 with named specialism subjects. The IB Diploma is read with equal fluency at UK universities and the typical Russell Group offer sits at 36 to 40 points. Both qualifications travel cleanly. The IB is fractionally more legible at UK admissions level simply because it is more common.
US universities accept both, but the IB is the more familiar handshake for American admissions officers. The French bac is accepted; mention tres bien or bien is highly regarded, and many bac candidates pair their application with SAT or AP exams to give a US admissions officer an extra reference point. For continental European universities outside France (Netherlands, Switzerland, Germany), both qualifications are accepted, with the IB the easier match for English-taught degrees.
Mobility, languages and bilingualism
If your family is genuinely mobile between countries, the IB wins. A child in IB MYP at an international school in Dubai can move into the IB Diploma at a school in Singapore or Madrid with limited disruption. A child mid-French bac is harder to move because the specialism choices made at the end of Seconde lock in the rest of the qualification. Out-of-network movement (from French bac to IB or A-Levels) is doable in Premiere but painful in Terminale.
For bilingual ambitions, the French system offers strong half measures. The Option Internationale du Baccalaureat (OIB) and the new Bac Francais International (BFI) deliver the bac with substantial teaching in a second language, usually English. The IB offers its own Bilingual Diploma route, which is well respected by universities looking for genuine bilingualism. For families who want their child's bilingualism explicitly certified at school-leaving, both systems can deliver, but the routes differ.

Which to pick if
If you are French and your child is likely to study in France: French bac, full stop. Parcoursup is built around it and the prepa route remains the cleanest path to the grandes ecoles.
If you are a non-French family in an AEFE school and unlikely to settle in France: IB. The recognition outside France is materially better.
If your child is targeting a UK university: either qualification works. Pick the one your school does well.
If your child is targeting US universities: IB is the marginally easier read, especially paired with the SAT.
If you may move countries before Year 12: IB. The continuity within the IB network is genuine and the French bac does not move.
If bilingualism matters and you are in France: the new BFI track of the French bac is excellent, often better at producing fluent bilinguals than the IB.

Common questions from AEFE families
Does the IB Diploma give access to Sciences Po? Yes, but Sciences Po expects subject coverage that some IB candidates miss. A Higher Level humanities subject (history or economics) and continued French at Language A or B level strengthens the file. Bac candidates with mention bien sit closer to the typical accepted profile.
Will my child lose their French if they switch to IB? Not if the school offers IB French A Language and Literature at Higher Level. The Bilingual Diploma route is built for this. The risk is in schools that offer only French B (ab initio or standard), which is too elementary for a francophone child.
Can a French bac candidate apply to Oxford or Cambridge? Yes, regularly. Oxford and Cambridge usually request mention tres bien (16+) with specified specialism subjects. The Grand Oral is increasingly read as preparation for the interview format.
