What does 'sufficient education' mean?

There are two alternatives here:

Either, you should have graduated from one of the Institute's 'Qualifying Courses'. These are Bachelors or Masters level courses in ergonomics and human factors which have been assessed by the Institute as providing a suitable knowledge base.

Or, you should be able to demonstrate a broad knowledge of the anatomical, psychological, physiological and systems bases of ergonomics and human factors. You should show a detailed knowledge of the application of at least one of these bases.
