There is nothing in the NEC that mandates this however there is certain criteria that is recommended or required per OSHA and IEEE standards.
It's entirely up to the user and typically depends on the nature of the installation (i.e., is grounding ultra critical to the system and/or for power quality purposes) and environment the grounding system is installed in (i.e., poor soil conditions).
What type of installation is this?
Yearly testing is ideal if you have the resources.

We use to build runways for airline transport and have someone come in from the union to govern our work and habits. He came in for this sole purpose. He was there to inspect bonding and grounding issues only.

Many municipalities in our area require a bonding audit for public pools every spring. I am not aware of any other yearly audits for electrical unless they may be private.

See the UL Directory under CABLE TRAYS (CYNW)
I believe that cable trays are supposed to be tested every six months for continuity.
This would fall under 110.3(B).
Search the UL book for testing of other products, or search the NEC for "testing" for some examples of required tests, some of which are to be made when the equipment is first installed, and where others are required.
This will give you some idea of them and you can choose what you want to include in your program.
Another good source of information, along these lines can be found in NFPA 70B

We have that ASS.GRD. program for cords and tools. We don't test feeders anymore.We change them when they fail.
