From NEAP Facebook Page
"Due to difficulty in securing the service provider for the printing of scannable answer sheets, NEAP is postponing the conduct of the 2015 Principals' Test, which was originally scheduled on 27 September 2015.
We will issue the memorandum/advisory next week setting the final date as soon as the printer has been identified and arrangements have been made.
Thank you for your understanding."
"You have a long time to review for the test"
