The world leader in IB revision and review 

OSC is a network of hundreds of IB teachers, co-ordinated by a professional management team. We visit schools, teach on vacation courses and create IB review content, supporting tens of thousands of IB students each year. 

We are honoured by the level of trust that is placed in us by parents, students and the wider IB community. For over 25 years, we have been dedicated to offering high quality IB support built upon a strong academic foundation. This is recognised in our British Accreditation Council (BAC) report. 

Over 70% of our students join OSC because a friend, family member or teacher has recommended they attend. What they tell us when they leave truly inspires us ...

OSC and IB Schools

Each year we visit hundreds of IB schools, providing presentation to students, parents and teachers on a wide range of IB related topics. We also run revision courses for a number of schools across the world. Each course is tailored to the needs of the individual school, ensuring we deliver the most effective course possible.

I wanted to email to say thank you for the visit. The feedback from the students was fantastic. The teachers said the form 11s returned from the lunchtime session buzzing with ideas. The evening session was also great. We have never had such a good turnout. The staff who were present were talking about it and commented on how compelling and informative the presentation was.

The students here really, really enjoyed the workshops and found them extremely useful. The immediate feedback that I had from students was exceedingly complimentary and I think they certainly benefitted from their time with Rosanna.

ISB was looking to partner with an organisation that had a solid track record in the field of IB teaching. It was important to us that our students would avail of expertise that came from experienced and qualified teachers who had a deep understand of the IB Diploma Programme. OSC ticked all those boxes.

St George’s British International School is delighted to continue our partnership with OSC. Their hugely experienced teachers provide a wonderful complement to our own superb staff, and together we feel this is a winning combination that will help all learners to even greater levels of achievement.

OSC and IBSCA

 Globally there are only ten Associations of IB World Schools with cooperation and licence agreements issued by the governing IB Organization, and OSC works directly with one of the largest of those – The International Baccalaureate Schools and Colleges Association of the UK and Ireland (IBSCA). IBSCA works throughout the UK and Ireland to support IB world schools, advise candidate schools on authorization matters, liaise with Higher Education on IB and provide professional development opportunities for IB professionals.

OSC is proud to work with IBSCA on workshop delivery, supporting their extensive range of professional development courses that are run exclusively for teachers. IBSCA is the provider of the IB Teacher Workshops; OSC manages the Workshops on their behalf.

OSC can commit all its resources to the IB because it’s the only educational programme we support. That expertise shows in every course we run and every guide we publish. It’s what makes us unique.

 

 


 

Built on strong academic foundations

 

Design

The academic structure of each OSC course has been developed in recognition of the relevant stage of the students' path through the IBDP and is based on solid pedagogical expertise.

Teachers

We employ hundreds of highly experienced IBDP teachers – most have been examiners. They understand students' learning and have the expertise to support diverse needs.

Content

Our Teachers and Authors create their classes and content based around their vast experience and the unique needs of students. They are up-to-date with syllabus changes.

Size

We are both large and small. The large number of students allows us to offer many parallel classes. But each class is small. Taken together, this allows individual needs to be met.


We have fantastic locations
