You must study all modules in sequence and pass each module’s Final Assessment before you can progress to the next module. There is no assessment for Module 1 as it is an introductory module.


All assessments are completed in the Tolley Assessment Centre and are sat once you feel ready, i.e. there is no set time when you must sit these.


All module assessments comprise a mix of 20 multiple choice, multiple response, pick from a list or true and false questions. You will get your result as soon as you finish the assessment and must answer 15 questions correctly to pass. You can take each module assessment a maximum of 4 times.
