Frequently Asked Questions for Diploma Candidates

How can I find my WSET candidate number?

You can find your candidate number by:

  1. Logging onto your Thinkific student account profile.
  2. Referencing a grade result letter for an assessment you have taken – your candidate number can be found on the top right corner of the letter.
  3. Logging on to the WSET Global Campus and accessing your student account profile.


Can I sit the D4: Sparkling Wine Exam before I sit D1: Wine Production?

Units D1: Wine Production and D2: Wine Business are intended to lay the foundation for subsequent learning in Units D3, D4, D5 and D6. The WSET stipulates that a candidate must sit the D1: Wine Production Exam before sitting any other examinations within the Diploma Program.

What do I need to bring to an exam?

You are required to bring:

  • Photo ID or you will not be permitted to write.
  • Glassware and a spittoon for exams D4, D5 and D3.
  • Your 8 digit WSET candidate number. To find this, log in to your IWEG student profile, or refer to previous WSET grade letter results.
  • Please bring pens/pencils/erasers etc. for the exam.

Please avoid wearing fragrances.

What happens if I am ill on the exam date, or something has kept me from adequately preparing for the examination and it’s past the registration deadline?

If due to illness or extenuating circumstances directly before or on the examination date you are unable to attend, you will have to fill out a Deferral of Assessment Form to be submitted for approval by the WSET Exams Team. If the WSET approves your application, you will be granted a credit to retake the exam at a later date.

You must contact the Diploma Manager by email regarding your situation as soon as possible in order to process this application. Any application received 7 working days after the assessment date will not be considered by WSET.

What is a passing grade for an exam?

The passing grade for each exam is 55%.

What happens if I fail an exam?

You can retake an assessment as many times as necessary to obtain a successful grade. You will have to pay to register to retake the examination. Please contact the Diploma Manager to register you for the next available assessment cycle.

When do I get to know my exam grade result?

Grade results take around 12-14 weeks to be processed by WSET UK after the assessment date. You will be contacted by email by the Diploma Manager when the results become available.


I’ve successfully completed all my unit exams – when do I officially graduate?

Congratulations! IWEG will be contacted by the WSET to confirm your successful completion of the Diploma Program, after which we will be sent your certificate and pin within 50 days to mail directly to you. Please confirm with the Diploma Manager your most current mailing address.
