Special measures ensure improvements. A school subject to special measures will have regular short-notice Ofsted or Estyn inspections to monitor its improvement. The senior managers and teaching staff can be dismissed and the school governors replaced by an appointed executive committee. If poor performance continues the school may be closed as in the case of the Frank Montgomery School in Kent. The current circumstances under which a school may be placed in special measures, and the procedures to follow, are stipulated by the Education Act 2005. Prior to 2005 special measures were applied to any school which was failing to supply an
Manganin Manganin Manganin is a trademarked name for an alloy of typically 84% copper, 12% manganese, and 4% nickel. It was first developed by Edward Weston in 1892, improving upon his Constantan (1887). Manganin foil and wire is used in the manufacture of resistors, particularly ammeter shunts, because of its virtually zero temperature coefficient of resistance value and long term stability. Several Manganin resistors served as the legal standard for the ohm in the United States from 1901 to 1990. Manganin wire is also used as an electrical conductor in cryogenic systems, minimizing heat transfer between points which need electrical connections.
