Must all three VEs hold the required licence class to "prepare" an examination, or just one?

Question

47 CFR § 97.507 states that:

(a) Each telegraphy message and each written question set administered to an examinee must be prepared by a VE holding an Amateur Extra Class operator license. A telegraphy message or written question set may also be prepared for the following elements by a VE holding an operator license of the class indicated:

(1) Element 3: Advanced Class operator.

(2) Elements 1 and 2: Advanced or General Class operators.

If a VE team has (hypothetically) one Extra class VE and two Generals, cat the team administer all the elements or just the Technician test? Does the answer change if the Extra does all the work of generating the exams?

Answer 1

This answer is for valid for the US only:

47 CFR § 97.507 addresses the preparation of the telegraphy message or the question set. It does not directly address the testing session itself.

47 CFR § 97.509 addresses the testing session. Paragraph (b) states:

(b) Each administering VE must:

(1) Be accredited by the coordinating VEC;

(2) Be at least 18 years of age;

(3) Be a person who holds an amateur operator license of the class specified below:

(i) Amateur Extra, Advanced or General Class in order to administer a Technician Class operator license examination;

(ii) Amateur Extra or Advanced Class in order to administer a General Class operator license examination;

(iii) Amateur Extra Class in order to administer an Amateur Extra Class operator license examination.

(4) Not be a person whose grant of an amateur station license or amateur operator license has ever been revoked or suspended.

Since all three VEs will need to sign section 2 of form NCVEC 605 then it would make sense that all 3 VEs would hold an operator license of the class indicated it 47 CFR § 97.509.

I also found this in the [Volunteer Examiner Manual][1] published by the ARRL:

The three or more VEs required to oversee the separate examination area must each hold the appropriate class of FCC license as well as ARRL VE accreditation.

So again, it seems that if you want to administer a test, you would need 3 VEs that hold an operator license of the class indicated it 47 CFR § 97.509.
