Depends on your company, airplane, and what they have approved. How big or small are they?
If they've got a lot of pilots on the particular airframe, they may have in-house check airmen who can do everything, 135.293 (aircraft check), .297 (instrument check), and .299 (line check). If they don't have many pilots on the airframe, they may contract everything out to the FAA, or initials to the FAA and just do recurrents in house.
If they send you to a big box school for the type, they big box will do a .293 and .297, but the .299 will be up to your company/FSDO to accomplish.
It'll really vary from company to company.
