The Office of the Independent Adjudicator for Higher Education (OIA) is a company that handles students' complaints against universities within England and Wales.  The OIA does not investigate the merits of the original complaint, which must be done by a court.  It, however, reviews if the higher education institution followed their own procedures.  Its remit is limited to those complaints that have first been taken through the procedures of a higher education institution's own internal system without reaching a satisfactory conclusion in the view of the complainant.  Previously, all complaints to the OIA had to be made within three months of the conclusion of the internal investigation by the higher education institution (which should usually have resulted in issue of a 'Completion of Procedures' letter).  However, the following now applies: the complaint must be completed within one year of your 'Completion of Procedures' letter, except if your 'Completion of Procedures' Letter is dated on or before 8 July 2015 in which case The OIA must receive the Complaint Form within three months of the Letter's date.
