ISO certification needs to be renewed, by reassessment every 5 years. So unless GUE got reassessed in 2018 their no longer compliant.
Maybe I should have made it more clear by stating that those GUE courses that I listed above have been EN/ISO certified *since* 2013. I'm not sure if any additional courses got certified later.
My Fundies card was renewed in 2018 with the EN/ISO #'s on it, and it's up for renewal again this summer. It's pretty safe to say that the 2018 ISO re-cert is good till 2023.
