The Test of Knowledge (ToK)

A clear understanding of the legislative, financial and regulatory issues pertaining to dentistry is a vital component of the all-round competence of every dental professional as reflected in GDC guidelines for both the undergraduate dental curriculum and the profession as a whole.

This computer-administered test is aimed at assessing the extent of your knowledge in key areas while driving learning towards a broad and thorough understanding of the competencies as outlined in the VT and Dental Foundation Competency Document.

Format of the test

The test is comprised of two modules: The Prescribing module with a 100% passmark and a Main (managerial) module with a 71% passmark. The scores you obtain for both modules will determine whether you pass the test as a whole.

i.e. To pass the Test of Knowledge you will need to achieve:

100% for the Prescribing Module

plus at least 71% for the Managerial module =

The combined passmark must be at least 74%

N.B. If you score 74% or higher overall, but did not get 100% in the Prescribing module, you have NOT passed the Test of Knowledge.


Prescribing Module

You will start the test with a five-question prescribing module in which you must answer all questions correctly (passmark 100%). The use of the SDCEP ‘Drug Prescribing for Dentistry’ guidance for reference is permitted during the test.


Main (managerial) module

The second module is comprised of a random selection of forty-five questions from a large question bank. If you are taking the test more than once you will be presented with a different set of questions at each sitting. The questions are either in multiple-choice or multiple-response format.

Multiple Choice Questions Candidates select ONE answer from any number of (mutually exclusive) possible answers e.g.1. You have a pair of steel forceps that must be sent back to the manufacturer for repair. Having just used them, you have cleaned them thoroughly to remove all visible deposits. Assuming all necessary sterilising equipment is available to you, which is the most effective process to use to decontaminate the forceps before their dispatch?

  • Autoclave at 125-128 degrees Celsius for 5 mins
  • Autoclave at 134-137 degrees Celsius for 3 mins
  • Glutaraldehyde disinfectant
  • Hypochlorite disinfectant
  • UV light treatment
  • Wash with water at 95-98 degrees Celsius

Multiple Response Questions Candidates select ONE or MORE correct matching responses from any number of possible answers. To score on these questions, all of the correct responses must be selected, e.g.1. A new patient attends for routine check-up. What should you record?

  • Any disabilities
  • Medical history
  • Social history
  • Smoking/ alcohol history
  • E-mail address
On the day of your test

Your scheme Adviser will let you know whether you will be undertaking the invigilated test within the training practice or in an education centre as part of a study day.

If possible you should not practice the test on the day of the invigilated test, but we understand that given the cicumstances that some of the invigilated tests may be taken opportunistically within the training environment. 

You will be provided with the below guidance which you can use as reference throughout the test:

  • SDCEP - Drug Prescribing for Dentistry 

  • SDCEP - Antibiotic Prophylaxis Against Infective Endocarditis 

  • SDCEP - Management of Dental Patients Taking Anticoagulants or Antiplatelet Drugs 

You can have a maximum of three attempts to pass on the day of the Test.  If you fail to pass after your third attempt, you will need practise further and pass three practise attempts prior to arranging another sitting at a future date with your Invigilator.

Please note: The system will not prevent these further attempts from happening and this could result in a you believing you have legitimately passed only to find sometime later during reporting that a problem has been identified and nullified the result.
