Key D — 74 per cent
The passing score is 74 per cent: 26 of 35 questions for Technician and General, and 37 of 50 for Amateur Extra. The extra class element is longer, but the pass mark is identical.

-
E5A03 Explanation 3
Key C — 18 years
A VE must be at least 18 years old and hold an amateur licence of the class being examined for, or higher. There is no minimum age to hold an amateur licence itself.
Rule 47 CFR §97.509(b)(1) - VE qualifications
-
E5A04 Explanation 4
Key B — Amateur Extra operators accredited by a VEC
VEs must hold the class of licence being examined for or higher, so an Extra examination requires Extra class VEs, accredited by a VEC, and at least three of them must be present.
Rule 47 CFR §97.509(b)(3) - examination administration
-
E5A05 Explanation 5
Key A — 365 days
A CSCE is valid for 365 days, which is what lets a newly qualified operator use the new privileges while waiting for the licence database to catch up. Exam credit itself does not expire in the same way - it can be used toward a future upgrade session.
Rule 47 CFR §97.505(b) - CSCE credit
-
E5A06 Explanation 6
Key D — They must reasonably accommodate amateur service communications and be no more restrictive than necessary

Rule 47 CFR §97.15(b) - station antenna structures
-
E5A07 Explanation 7
Key C — Expanding the reservoir of trained operators, technicians and electronics experts
The five purposes cover trained operators, advancing the radio art, communications skills, a pool of operators for emergencies, and international goodwill. Cost savings and revenue are not among them, which is exactly why substituting for other radio services is prohibited.
Rule 47 CFR §97.1 - basis and purpose
-
E5A08 Explanation 8
Key B — An amateur station that transmits signals for the purpose of controlling other amateur stations
Auxiliary stations exist for control purposes - linking a remote receiver to a main station, for example - and are restricted in which bands they may use and in the purposes they may serve.
Rule 47 CFR §97.201 - auxiliary stations
-
E5A09 Explanation 9
Key A — Routine messages that could reasonably be sent by telephone or another radio service instead

Rule 47 CFR §97.113(a)(5) - prohibited communications
-
E5A10 Explanation 10
Key A — International Morse code practice for people learning the code
