Under OPM regulations, federal agencies may make temporary appointments when they do not need an employee's services on a permanent basis. Until 1985, temporary appointments were much as they are today: limited to one year with a maximum one-year extension. In 1985, OPM made several policy changes to give agencies greater flexibility to meet mission and budgetary challenges. From 1985 through 1994, temporary appointments could be extended for up to four years, in one-year increments.
