In addition to my self having gone through the Citizenship process recently.
Additionally several native nationalities have an exception:

I thought it was clear (since I quoted it) that I was responding to the claim that there are no English language proficiency tests as part of the UK Citizenship tests as not being correct. In some circumstances there are (e.g. Your degree is not in English and you are not from a recognized English speaking country). Not sure what is contentious about that statement of fact?
I believe cannonpr meant that no English language proficiency tests were required to be taken as part of the citizenship tests, as they accept a large number of qualifications (and thus only need to take the test if you do not hold one of these qualifications). So while you might have to take a test, it is separate from the UK citizenship tests.
