Can some one guide me how can we change our membership status from affiliate to technician.

Mr. Shahid Javed, Recently I've received my Technician Membership that was upgraded from Affiliate Member and it was quite quick process. All you must have is your NEBOSH IGC Certificates and CV/Resume showing your experience in OSH, as the requirements for the review by Membership Audit and Review Panel. What you need to do is to send an email to Membership [Membership@iosh.co.uk] that you will upgrade you membership to Technician Membership. Then surely they will reply on your email saying that you need to send your scan copy of NEBOSH IGC Certificates and CV/Resume for review by the Membership Audit and Review Panel. And by three (3) weeks i received my new certificate with Technician Membership. Hope this may help you.... GOD BLESS.....
