Purpose: The TRR is held to verify readiness for Government testing. Description: The TRR is the Government's decision milestone that determines the completion of ICPI and CFI. The TRR may be conducted on an incremental basis as established in the Trainer TEMP.Typically the first TRR (TRR 1) is held prior to GPI and a second one (TRR 2) is held prior to GFI.Additional TRRs may be held as required. The first TRR occurs after the Contractor has completed HSI and successfully completed the Test Procedures tests.he TRR mission exercises are defined in the Government-accepted TP and other Government-accepted test plans as documented in the Trainer TEMP. The TRR mission exercises are the primary method for determining trainer readiness for the Conformance Inspections after the CPI deficiencies have been resolved.
