The Inspectorate carries out a regular inspection of Scotland's prisons (including the privately run prisons). Each of Scotland's 16 prisons is normally subject to a full inspection every three years. Annual shorter, follow-up visits - which may be unannounced - are also made. Issues examinined include actual physical conditions, the quality of prisoner regimes, morale of staff and prisoners, facilities and amenities available to staff and prisoners, safety issues, and decency and contribution to reducing re-offending. The Inspectorate also inspects Legalised Police Cells (mainly used in rural parts of northern Scotland) and the conditions of prisoner escort arrangements.
