Don't quote me on this ... but in AE as far as the focus of our college education for a teaching career, we usually refer to it as "my major" rather than as a specialiization.
This is generally true on the undergraduate level. However, in the graduate level 'specialize' is used quite frequently.

My point was that it's often difficult to tell when certain broad and open ended subjects such as "elementary education" overlap. They're almost difficult to know where to draw the line. I've ordered books on "intermediate Spanish" only to find out that they contain a lot of the same material that was in the "beginning" Spanish books.
You can specialize in elementary education rather than secondary education or adult education. The degree of difficulty in the materials taught may actually be the same, but you don't teach adults the same way you teach elementary school children or secondary school children. This is where the specialization comes in.

I googled and found over 1 million listings of "is specialized in."
I have not heard or read "specialize in" used in the passive until just now. I just did the google search myself, and most of those listings are advertisements or marketing pieces. Such pieces often do not adhere to standard English usage.
He specializes in cardiology.
He specialized in cardiology.
He is specialized in cardiology. <-- This sentence is not correct. Think about it logically. The man did the specializing. The specializing was not done to him. Remember, passive voice is used when the subject is the recipient of the action. Example: Active --> George paints with acryllics. Passive --> George is painted with acryllics.
His specialty is cardiology.
The store specializes in fishing gear. <-- While this sentence is technically correct, I would prefer: This is a specialty store for fishing gear. [Perhaps the store focuses on just one kind of fishing gear such as gear for ocean fishing, but it isn't really necessary to be that specific in order to use specialize].
The store is specialized in fishing gear. <-- This sentence is not correct. Once again, the store did the specializing, or rather the owners did. The specializing was not done to the store.
