Have no idea --it gives you a Level 5/6 qualification so you can train others in Customer Service -never worked for anyone in my 65 years so pretty experienced in getting by--there was no prerequisite to get on course just be on PUP/DOLE --just have to log in and do all the modules and do some project work ,then they rate you at the death---appears to be a few different results --success, or with attended with merit --or just attended but no fail but you can claim to be trained to Level 5/6.
Loughlinstown Training Centre --did a Driving Course course in the past as I know a guy who did it --
Airport Driving School do a Train the Trainer course but its a bit of a catch me --they guarantee the result if you spend 2/3 K--you should call them and suss it out and see will they point you in any direction --their course might have some Intreo accreditation so it would be in their interest in getting you approved --but I gather not nice people to deal with --check out ISM and Alexandra Schools sites they both do lots for Intreo !
