Decided to go for my RoSPA Gold

[Grahamm]

pass IAM and that's it for life, Rospa resit every 3 yrs so have a higher membership rate due to peeps failing or not bothering after 3 yrs

The IAM have recently introduced the "Masters" qualification which (presumably in an attempt to one-up RoSPA) is a two year requalification, although you still keep your standard IAM Membership even if you don't requalify.
