Psychometric principles, particularly Item Response Theory (IRT), provides the tools and processes by which CAT exams can be developed and administered properly--they are intertwined in their workings.

There are many CAT exams administered today, and groups are still gravitating toward CAT. A general page that lists programs that use it is:

I'm sure it's not too interesting, but adaptive testing has its roots back to Binet and his first tests to assess intelligence and apply IQ scores..of course it was a manual process, but adaptive nonetheless.

adaptive testing and pyschometrics aren't mutually exclusive. I believe. I'd have to ask the LPI pschyometrician about it again.

Adapative testing would not interfere with psychometrics but you couldn't directly compare it with a non-adaptive test. In theory, a well designed adaptive test would drill down and closely define a test taker's knowledge. In practice there doesn't seem to be many examples of adaptive testing in the real world.
