Currently hold Silver Rospa .... And looking into local Iam group for more social side of things Both work from roadcraft with minor differences in their execution . Main difference at present is as mentioned IAMroadsmart as long as you pay your yearly subs your an advanced rider Rospa.. every three years you must take a retest as well as paying your annual dues to keep your advanced status. . (Better in my opinion ) I undertook no formal training for my Rospa apart from completeing 2 bikesafe courses and the DSA enhanced riders scheme . Applied for the Rospa Test and achieved Silver .Just recently had my compulsory 3 yr test and achieved Silver again. Regarding if it makes you safer ... it depends on how you apply it. Regarding riding with others if your riding with a mixed bag of riders then the risk is higher due to varying styles ,but if for instance riding with a group of similar matched rider styles ( eg advanced group rides) then it reduces the group risk as all working on same principles.
