There is no "certification" to drive a ground rod. All telecommunications systems are required to be bonded to the household electric service ground. Bonding prevents a difference in potential between the communications system and the electric service. Normally a household electric service is grounded to the incoming water main and a short #6 AWG pigtail is provided as a utility bonding point. In some cases the electrician will install a ground rod also.
Bonding the systems together, to the same ground, prevents a potential difference between the two systems. A difference in potential can lead to the communications system ground becoming the ground for the electric system, and any fault voltage will travel along the communications conductor to ground.
In the case of your Amish customers (I assume they have no electric service) it is proper to install a ground rod, as there is no utility bonding point. You will also find some older homes with no electric service ground.
