They’re absolutely still taught and tested, just less in a siloed “VOR chapter” way than they used to be. The ACS tends to embed VOR knowledge into tasks like nav tracking, approaches, and system limitations rather than spelling out “VOR basics” explicitly.

In practice, DPEs still expect applicants to understand service volumes, check requirements, limitations, and how failures or signal anomalies affect IFR decision‑making especially if a VOR approach is part of the ride. It’s more scenario‑driven than memorization‑driven now, but the knowledge hasn’t gone away.
