If you plan to work or study outside the UK, we recommend checking whether this qualification meets local requirements. Find out more about the international recognition of Open University qualifications.
As a student of The Open University, you should be aware of the content of the qualification-specific regulations below and the academic regulations that are available on our Student Policies and Regulations website.
We regularly review our curriculum to keep it up to date. This means the structure, availability, and content of the course or modules may change. We’ll update this page as soon as possible if there are any changes. If you have already registered for this qualification, we’ll inform you in good time of any upcoming changes where practicable. For more details, see our Academic Regulations or contact us.
You can achieve this diploma in as little as two years and have a maximum of 12 years to complete it. Our module-by-module approach gives you the flexibility to complete your qualification at a pace that works best for you.
You can complete this diploma in two years by studying at a pace equivalent to full-time. That’s similar to a student at a campus-based university.
You can complete this diploma in four years by studying part-time. That’s roughly half the rate of a student on a full-time course at a campus-based university.
At the OU, flexibility and support go hand in hand. You’ll be in control of when and where you study, with clear deadlines to guide your progress. Whether you’re balancing work, family or other commitments, our approach helps you fit learning into your life. Students consistently praise the support we provide, and from the very start, you’ll be part of a vibrant OU learning community.
As you progress through your qualification, you’ll have access to a dedicated online study space, expert tutor guidance, optional live tutorials, and a wide range of resources to help you succeed. The sections below outline what you can expect.
Your module website will be a central hub for your learning, giving you easy access to:
Discover how the OU’s module websites, course materials, and support tools help you study online with confidence.
Each module has a dedicated tutor who will guide you through your studies. They’ll provide feedback, help you find resources, mark your assignments and support your learning journey.
For extra support, you can attend optional live tutorials with your tutor. These are usually conducted online, and most are recorded so you can review them later.
See how OU tutors and tutorials help you build confidence, connect with others, and get the support you need to succeed in your studies.
Our assessments reinforce what you’ve learned and show your understanding. Assessment types vary by module and may include:
Throughout your studies, you’ll have access to a wide range of support services and be part of a vibrant learning community. Our subject-specific Student Support Teams can help with general queries and any updates to your OU account. You’ll also benefit from:
Discover the support network and learning tools you'll have access to throughout your studies.
There are no formal entry requirements for this qualification; however, you must have the required mathematical skills to study the compulsory module Essential mathematics 1 (MST124), including:
Check you’re ready for MST124 and see the topics it covers.
If you don’t feel you have the required mathematical skills, you can study an additional module, Discovering mathematics (MU123), to give you the knowledge and skills you need.
Ideally, you’ll also have some basic knowledge of computing.
If you’ve studied at university level before, you may be able to transfer the academic credit you've been awarded towards an OU qualification. This could save you time and money by reducing the modules you need to study.
It’s not just university study that can be considered; you can also transfer study from a wide range of professional or vocational qualifications, such as HNCs and HNDs.
You should apply to transfer credit before registering, at least four weeks before the registration closing date. We will need to know what you studied, where, and when, and you will need to provide evidence of your previous study.
