Arcanists using Focused Arcane School

[RealAlchemy]

Can an arcanist with the School Understanding exploit take Focused Arcane School from the APG?

[Melkiador]

"The arcanist can select one arcane school from any of the schools available to a character with the arcane school wizard class feature..."

I would say they could.

For comparison, the bloodline version has much tighter language. "The arcanist must select an ordinary bloodline with this ability"
