The INCOSE SE Handbook version 4 release in January 2015 will be followed on 1 May 2015 by a new version of the Certification knowledge exam.  INCOSE Certification candidates who plan to take the knowledge exam in the Spring of 2015 are advised not to schedule their exam between 16 April 2015 and 30 April 2015.  During that time period, INCOSE and its testing provider will be updating candidate records to re-assign them to the new exam.  Only individuals whose testing eligibility period ends in April 2015 will be allowed to take the exam during that blackout period.  To check on your eligibility ID code or its end date, candidates should look for an email received shortly after submitting their individual application and payment.  If they cannot locate that email, they may contact the Certification Office for the information.
