Wine knowledge

To enrol onto the Diploma, you must have successfully completed the WSET Level 3 Award in Wines (previously known as the WSET Level 3 Award in Wines and Spirits). We do not accept any other previous learning for enrolment on this course.

English language skills

While many people successfully complete the Diploma in their second or third language, a strong grasp of written English is required for this course - assessment for the Diploma requires an ability to write long- and short-form answers.

Students whose first language is not English are strongly recommended to have an IELTS score of 6.5 or above or be able to demonstrate an equivalent ability level. If you have any concerns about your English language skills, please don't hesitate to get in touch.

The Diploma represents a significant time commitment, with a minimum requirement of 500 hours total study time. This is inclusive of approximately 125 hours classroom or online delivery time. No matter which study option you choose, it is important that you're prepared to dedicate a substantial amount of study time to successfully complete this course.

Once you enrol onto a course you will be given access to the digital course materials and a detailed course programme. It is essential that you have read the relevant chapters of the online book ahead of the corresponding classroom or online sessions. You will be participating in high level discussions, workshops and in-depth tastings, which you will only be able to make the most of when you are familiar with the subject.

As a minimum we recommend that students have completed the following before starting their course:

  • Re-read the textbook for the Level 3 Award in Wines. You may want to buy the most recent version if you studied the pre-requisite qualification sometime ago
  • Read through the specification and theory guidance document (available on registration) to familiarise yourself with the qualification structure and assessments
  • Take a look at the Level 4 SAT and the tasting guidance document (available on registration)
  • Start reading through the D1 materials (available on registration)


How will I be supported?

We appreciate that the Diploma represents a significant mental, physical and financial challenge. We want every student to fulfil their potential and complete the qualification with a feeling of achievement, and sense of accomplishment. That’s why, in addition to the delivered classroom or online content we’ve created a range of support materials, activities and events exclusively available to WSET School London students. Some examples of these additional resources can be found below:

Online resources

In addition to the qualification resources, WSET School London uses WSET's Online Classroom to provide students with the opportunity to participate in extra practice papers, quizzes, and virtual tastings; all aimed at better-preparing students ahead of associated assessments. These activities are a great way to test your knowledge and progress through the materials and familiarise yourself with what to expect in each of the examinations.

Exam preparation activities

Your taught course will include many workshops and feedback opportunities to help you prepare for assessments. For those students looking for more support, a range of extra-curricular activities are offered by WSET School London. These include winery/vineyard visits, in-person tutored and blind tastings, webinars and exam strategy days. Many of these activities are free or offered at a nominal cost.
