This diploma of higher education has two stages, each comprising 120 credits.

  • In Stage 1, you’ll study a 60-credit introductory science module and, depending on your chosen route, a 60-credit module or two 30-credit modules.
  • In Stage 2, you’ll study 120 credits from your chosen route.

Prepare for OU study with an Access module

We offer two starting points depending on how confident you are or how long it’s been since you last studied. Choose to dive straight in at Stage 1, or if you’d prefer some extra preparation, you can get started with an optional Access module. See Entry requirements for more details.

You’ll study a 60-credit introductory science module. And, if you choose the multidisciplinary route, you’ll study a 60-credit module. If you choose the physical sciences route, you’ll study two 30-credit modules.

Learning outcomes, teaching and assessment

This qualification develops your learning in four main areas:

  • Knowledge and understanding.
  • Cognitive skills.
  • Practical and professional skills.
  • Key skills.

Credit transfer

If you have already studied at university level, you may be able to count it towards your Open University qualification – which could save you time and money by reducing the number of modules you need to study. At the OU we call this credit transfer.

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 for credit transfer before you register, at least 4 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.

For more details of when you will need to apply by and to download an application form, visit our Credit Transfer website.

On completion

On successfully completing this course, we’ll award you our Diploma of Higher Education in Natural Sciences.

International recognition

If you intend to use your Open University qualifications to seek work or undertake further study outside the UK, we recommend checking whether your intended qualification will meet local requirements for your chosen career. Find out more about international recognition of Open University qualifications.

Regulations

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.

There are no formal entry requirements for this qualification; however, to get the best from it you’ll need some knowledge of science concepts and mathematical skills, and the ability to read and write to a good standard of English.

Check you’re ready for Questions in science (S111) with our self-assessed quiz.

If you’re thinking about choosing physics or astronomy and planetary science, check you’re ready for mathematical study at this level.

How much time do I need?

  • Most of our students study part time, completing 60 credits a year.
  • This will usually mean studying for 16–18 hours a week.

Preparing for study with an Access module

Students who start their study with an Access module are more likely to be successful when they advance to Stage 1 of their qualification. They’re specially designed to give you a gentle introduction to OU study, boost confidence in your study skills, and help you gain a broad overview of your chosen subject area.

You’ll also benefit from:

  • feedback from your tutor through regular one-to-one phone tutorials
  • support from a dedicated team throughout your study
  • detailed written feedback on your work.

The Access module we’d recommend studying in preparation for this qualification is our:

Science, technology and maths Access module

What you will study

This multidisciplinary module is an ideal starting point if you have little or no previous knowledge of the sciences, technology and mathematics. It’ll help develop your study skills in advance of your OU qualification, and you get to explore a number of STEM subjects including science, engineering and design, environment, mathematics, and computing and IT.

See how our module websites work.

Tutor support

Student, Joe, talks about balancing working at the NHS and studying with the OU and how he has the best of both worlds.

You’ll have a tutor for each module, who will introduce themselves before the module begins.

Throughout the module, they will:

  • mark your assignments and give feedback to help you improve
  • guide you to learning resources
  • support you, whether with general study skills or help with a specific topic.

Tutorials

Tutorials usually take place online, and they’re always optional.

Online tutorials are live presentations with module tutors in dedicated online tutorial rooms and are sometimes recorded.

Assessment

Our assessments are all designed to reinforce your learning and help you show your understanding of the topics. The mix of assessment methods will vary between modules.

Computer-Marked Assignments

  • Usually, a series of online, multiple-choice questions.

Tutor-Marked Assignments

  • You’ll have a number of these throughout each module, each with a submission deadline.
  • They can be made up of essays, questions, experiments or something else to test your understanding of what you have learned.
  • Your tutor will mark and return them to you with detailed feedback.

End-of-Module Assessments

  • The final, marked piece of work on most modules.
  • Modules with an end-of-module assessment won’t usually have an exam.

Exams

  • Some modules end with an exam. You’ll be given time to revise and prepare.
  • You’ll be given your exam date at least 5 months in advance.
  • Most exams take place remotely, and you will complete them at home or at an alternative location.
  • If a module requires you to take a face-to-face exam, this will be made clear in the module description, and you will be required to take your exam in person at one of our exam centres.

Progressing to a point where I felt more comfortable writing my assignments, and having my scores reflecting that, made me quite happy because it showed the hard work was being rewarded.

Skills for career development

In addition to specific learning outcomes, this diploma develops a variety of skills that are highly valued in the labour market, such as analytical, numerical IT and communication skills, teamwork, and problem solving. Many of these translate very smoothly into the modern workplace, which is increasingly concerned with knowledge management and the effective communication and presentation of ideas and arguments. You’ll develop critical thinking and independent research skills, and the ability to take the initiative – all valuable assets in today’s competitive environment.

You’ll also have a good understanding of where your strengths and interests lie, and be well prepared for your next step – whether it’s further study or training, or employment.

Career relevance

Scientists are in demand in the jobs market, particularly if they also have good interpersonal skills and some workplace experience. The logical, reasoned approach needed for science study is relevant to many roles in the financial, business and public sectors – and employers in all fields put a high value on anyone who can deal competently with a large amount of complex information and turn it to good use. The ability to select and analyse relevant data and to present conclusions concisely and logically is essential in most lines of work, as is the ability to communicate clearly both orally and in writing. 

Other careers

People with science qualifications are well placed to enter both scientific and non-scientific jobs. The logical, reasoned approach needed for science study is relevant to a wide range of financial, business and public sector employment.

In addition to improving your career prospects, studying with the OU is an enriching experience that broadens your horizons, develops your knowledge, builds your confidence and enhances your life skills. 

Exploring your options

Once you register with us (and for up to three years after you finish your studies), you’ll have full access to our careers service for a wide range of information and advice – including online forums, website, interview simulation, vacancy service as well as the option to email or speak to a careers adviser.  Some areas of the website are available to see at any time, including help with looking for and applying for jobs. You can also read more general information about how OU study enhances your career.
