1.22 The Prison Service could not provide a clear audit trail between historical performance, in terms of fixed fines for specific incidents or performance points against baseline, and the actual financial deductions. The earlier financial deductions at Altcourse and Parc were reduced following negotiations between the Prison Service and the contractors. These negotiations were not solely concerned with the prisons' operational performance. They also took account of problems with inflexible contract monitoring. The Prison Service also told us that financial deductions in the second performance year at Lowdham Grange were offset in return for other services provided by the contractor. The Prison Service does not monitor trends in performance points over time and consequently there is no easily-accessible historical record of past performance points and the incidents which led to them. However, the Prison Service has recently tightened these procedures.
