Patrick, I let my iNARTE certification end the end of 2022. I had held this certification since it was created. Never once did an employer seem to care about it. Personal experience. Take it for what it is worth. Ghery S. Pettit From: Patrick Sent: Tuesday, January 10, 2023

Re: [PSES] Good Morning - bad breakup?

So, it's true! With most breakups, parties hire lawyers and split assets. Since I'm both an iNARTE Certified EMC Engineer and Member IEEE EMC Society, I wonder which party will claim me? ;-) On the serious side, I wonder if employers will continue to value either certificate. Did they ever?

[PSES] Good Morning - bad breakup?

Hi All - I read an article this weekend where IEEE EMC Society is breaking up with iNARTE. I struggle to find verification of this. Wondering if this is fake-news, or did they really end the relationship? -Patrick - This message
