It will not be possible to apply for Academic Technology Approval Scheme (ATAS) clearance between 20 December 2013 and 3 January 2014, and processing times for applications submitted before 20 December will be longer.
The ATAS team has provided the following information:
"The ATAS online application system will be closed for the Christmas and New Year period from 17:00 on Friday 20th December 2013 until 17:00 Friday 3rd January 2014. It will not be possible to submit new applications during this time. The ATAS mailbox will not be checked regularly over the period. Applicants are also advised that there are four public holidays during this period, so the 20 working days processing time target will temporarily extend to 24 working days from the date of submission in the case of satisfactorily completed applications. We therefore take this opportunity to remind applicants to take care to submit applications accurately, following the advice on the main ATAS website, to avoid unnecessary delays".
UKCISA cannot provide any further information about this, but institutions might be able to contact the ATAS team in emergencies.
