If you are hearing sounds as you read the post,  

Pilots that come to a Part 142 training center are often confused.  They think a FAA Part 142 training center is like a the Part 61 flight school where they received their training for their private or commercial.  At a Part 61 flight school the CFI can endorse any training within the limits of their flight instructor certificate.  At a Part 142 training center, students have to enroll in an approved course and all the training has to be conducted under that syllabus.  So unless it specifically states in the Part 142 approval that annual refresher training can be used for example to satisfy the requirements of BFR, or that the instrument training can be used for an IPC, don't ask your instructor if they can "just sign you off for.... "

Companies offer a list of approved courses under their Part 142 certificate, and it varies from training center to trainimy center.  If its not on the approved list, the company can't provide the training.  Things that may not be approved may include, BFR, IPC, LOS, Incemental Checking, SIC to PIC upgrade, Commercial to ATP prep during annual recurrent training, endorsement to take the CFII checkride, or foreign license validation.  Those are just a few.
