Exams at iBOS


iBOS is a JCQ-approved exam centre which offers public examinations for International A Levels and International GCSEs through Pearson Edexcel, recognised globally for its high standards and rigorous assessments.

International A Levels at iBOS are advanced qualifications typically undertaken by students aged 16 to 19. These qualifications provide a pathway to higher education and are equivalent to UK A Levels. Each iA level subject consists of four to six modules, which will be cashed in at the end of the course to produce an iA level grade. Students usually study three or four subjects over two years (Year 12 and Year 13), with assessments conducted at the end of the course. If the school and teachers believe that the student is ready to take some modules to sit the public exams for specified modules they will be entered for these exams in Year 12. iBOS offers a diverse range of International A Level subjects.

International GCSEs (Year 10 and Year 11) are typically completed over two years and are available in a wide range of subjects. iBOS delivers Pearson Edexcel International GCSEs, providing students with a comprehensive curriculum designed to prepare them for further education, employment, or vocational training.

Where applicable, assessments for both International A Levels (Year 12 and Year 13) and International GCSEs (Year 11) at iBOS include written examinations, oral examinations, and practical evaluations. The school ensures that examinations maintain high validity, reliability, and fairness standards, aligning with international benchmarks for global recognition.

By offering Pearson Edexcel’s International A Levels and International GCSEs, iBOS provides students with internationally respected qualifications, empowering them with the knowledge and skills needed for future academic and professional endeavours. 

Key definitions

Entry Centre: This is the centre that enters the student for their public examinations. It means that iBOS is responsible for registering students for public examinations on the Pearson Edexcel portal, such as iAL and iGCSE. The entry centre (iBOS) confirms that the student is enrolled and studying at iBOS and is responsible for post-examination matters including certifications and remarks.

Entry Fee: The fee charged by the awarding body to the entry centre for each paper or subject registered for an exam. Parents are advised to pay the entry fee per the invoice, including exam administration, certification costs, and other associated expenses.

Host Centre: An institution, such as an exam centre or school, that allows external students to take exams at their facility. The host centre is not involved in registering students for exams; instead, it provides the venue for examination sessions and arranges invigilation and administration of paper dispatching.

Hosting Fee: The hosting fee refers to the charges incurred by the exam centre where students will sit for public exams. The centre is responsible for invoicing the hosting fees, which should be paid according to the invoice terms.

Exam Entry Deadline: The exam entry deadline is the cutoff date by which students must be registered for their public examinations, such as iAL and iGCSE, on the Pearson Edexcel portal through their entry centre. Please meet this deadline to avoid incurring a late fee.

Cashing in Results: It is a process by which the individual modules within an A-level subject are combined at the end of the course to determine the overall A-level grade. Typically, each A-level subject comprises four to six modules, and students generally study three or four subjects over a two-year period (Year 12 and Year 13).

Award Certificate: Award certificates are official documents issued by the awarding body to students to acknowledge their academic achievements and exam results. These certificates typically contain the student’s name, details of their award grades, and other relevant information. They are significant for university applications and enrolments as evidence of the student’s academic performance and qualifications.

Appeals: Appeals refer to the process wherein a student, dissatisfied with their exam results, requests a re-evaluation to obtain improved grades. To initiate an appeal, the scripts are downloaded from Pearson upon request from parents and students. It’s important to note that appeals must be made within a specified deadline and may incur additional costs.


At iBOS, students are expected to take exams through a structured process to ensure fairness, consistency, and adherence to examination regulations. Here’s how the exam process works:

  • Sitting exams at iBOS: If students wish to sit their exams at the iBOS school site in Clapham, London, the school generates an invoice including the entry fee, hosting fee, invigilation fee, and certification fee.
  • Host Centres: In the event that the student is not in London to sit their exams,iBOS recommends exam centres based on previous associations or collaborations in the students’ geographical places. Parents are advised not to arrange exam centres independently without consulting the exam officer.
  • Exam Entry:iBOS handles exam entry procedures by entering students for exams through the Pearson Edexcel portal. The school invoices parents for the exam entry fee, administration, and certification expenses.
  • Payment:Parents are required to pay the entry registration fee to iBOS according to the school’s invoice. Additionally, parents are responsible for liaising with the exam host centres and paying any hosting fees invoiced by the host centres directly.

By following this structured approach, iBOS ensures that students have access to appropriate exam centres, comply with examination regulations, and have the necessary support throughout the exam process to maximise their success.

DISCLAIMER – Please note that while iBOS makes every effort to recommend suitable exam centres in various countries, there may be instances where certain countries are not as cooperative in hosting students for exams. In such situations, iBOS may require parents to assist in arranging exam centres or exploring alternative options. Where the student lives in a country where there are no host centres, the students need to travel to a nearby country to sit their public examinations.

We appreciate your understanding and cooperation in navigating these circumstances to ensure a smooth exam experience for all students.
