We offer a range of units for trainees, from KS3 to A-Level. All are supported by excellent interactive “SnapRevise” resources. You will have access to all three sciences at GCSE and your specialist subject at A-level. You can to refer to the resources whenever you need them in your training year – even after your SKE is complete.

The Sussex online Chemistry SKE is available as an eight,12,16, 20, 24 or 28-week course.

Once you have enrolled, you will be able to select from the following four-week units:

  • KS3 Science (focussed on developing your non-specialist sciences to KS3 standard)
  • KS3/KS4 Practical Science (Practical Science Skills across the 3 Sciences, but specialising in Chemistry)
  • GCSE Chemistry - Atomic Structure, Periodic Table, Bonding, Quantitative Chemistry
  • GCSE Chemistry - Chemical Changes, Rates, Organic Chemistry, Chemical Analysis
  • A-Level Chemistry - Physical Chemistry, Bonding, Energetics, Rates and REDOX
  • A-Level Chemistry - Inorganic Chemistry, Organic Chemistry
  • A-Level Chemistry - Physical Chemistry II
  • A-Level Chemistry - Inorganic Chemistry II, Organic Chemistry I


  • 28-week course

    You will select any seven units from the six Chemistry units and the two general science units, giving you a comprehensive background in the Chemistry curriculum from KS3 to A-level.

  • 24-week course

    You will select any six units from the 6 Chemistry units and the two general science units. You can cover all the GCSE and A-level curriculum, or cover the general science units, GCSE and the Year 12 content (which is the A-level material that you are most likely to be asked to teach in the early years of your career).

  • 20-week course

    The 20-week course allows you to select any five units. You can focus on GCSE or the A-level curriculum and also familiarise yourself with the curriculum in other key stages.

    The 16-week course is very flexible. You select any four units. If you will be teaching in an 11-16 school, then you can focus on KS3 and KS4 units. Alternatively, you can cover the full A-level curriculum and ensure you are prepared for the challenge of post-16 classes. You are also free to select units that span KS3 to A-level to give you a broad overview of the Chemistry curriculum.

  • 12-week course

    On the 12-week course you select any three units. For most students we suggest completing the KS3 Science unit and the two GCSE units, but get in touch with us at if you would like to do a different selection.

  • Eight-week course

    On the eight-week course you select any two units. Most students will complete both GCSE units or the KS3 unit and one of the GCSE units. Get in touch with us at if you would like to do a different selection.

Application deadlines

Our SKE courses have different deadlines depending on the length of the course you’re applying to.

See our application page for more information.

Eligibility and funding

SKE courses are funded by the Department for Education (DfE) if you have been offered a place on a PGCE course with enrolment on an SKE course as a condition of acceptance.

Find out more about SKE eligibility and funding.

Self-funded SKEs

We also offer a self-funded SKE route for:

  • teacher trainees who are not eligible for DfE funding
  • qualified teachers who want to teach a new subject, or refresh their subject knowledge before returning to teaching after a break
  • anyone considering teaching as a new career who wants to increase their subject knowledge before applying for teacher training.

Rather than four-week units, self-funded SKEs are based on blocks of 100 hours of study.  You can choose which units you want to study and add additional units as you progress. 

The cost is £800 for one 100 hour unit, and £500 for each additional unit. Fees can be paid by you or, if relevant, by your school/institution (schools within the Sussex Partnership or PGCE Pedagogy and Practice Partnership can apply for partnership rates).

If you have any questions about self-funding your SKE, email


In addition to input from specialist subject tutors you will also receive:

  • a physical copy of a GCSE and/or A-level textbook, as well as a revision guide. 
  • a full subscription to the excellent SnapRevise materials, an interactive course of videos and short assessments (You will have access to all 3 sciences for GCSE and the materials for A-level in your specialist subject. You’ll retain access to these until the end of your training year)
  • a fully paid subscription to ExamPro, a database of past KS3, GCSE and A-level exam questions
  • access to thousands of relevant physical and e-books through our Library
