Royal Decree 99/2011 of 28 January 2011, which regulates official PhD studies, establishes a time limit for the completion of PhD studies. 

The duration will be a maximum of three years for full-time students or five years for part-time students, in both cases from admission to a PhD programme (15 October) until the presentation of the PhD thesis at the Academic Committee of the corresponding program.

If the application for the thesis to be deposited before the Academic Commission of the programme has not been submitted before the end of the aforementioned period, the Committee may authorise the extension for a further year, which may exceptionally be extended for an additional year under the conditions established in the corresponding PhD programme.

Depending on the completion of full-time or part-time studies, as well as on the exceptional circumstances envisaged, you will have the deadlines indicated in the following table.

The request for extension must be addressed to the Academic Commission of the programme within the four months prior to the end of the period of stay in the programme according to their dedication regime. Once all signatures have been collected, the application must be submitted to the Secretary's Office of the Centre responsible for the PhD Programme. For the purposes of this calculation, periods in which the PhD student has been authorised to leave the programme temporarily for any of the reasons set out in the regulations in force will not be taken into account. Each student can consult their deadline for remaining on the programme in the RAPI2 application.

Students who wish to request an extension for the completion of the Doctoral Thesis, should consult the deadlines and regulations of permanence in the Continuity section of the UCM Doctoral School's website.
