Correct - identify the station - NDB, VOR or ILS is most important.
The ADF is monitored throughout an NDB approach for reasons stated above.
VOR/ILS/DME requires initial identification, thereafter, no need to monitor.
If they fail, a flag will appear.

One thing is - I used to train pilots to this procedure.
PF to PNF command should be i.e. "
tune and identify the 24L ILS" -
That should be the wording during your approach briefing.
Your mistake as PF might be "set 113.1" and... the proper frequency might be 111.3.
A notorious "killer" in everyday operations and a bust... for a check flight.
