Hi Mr Original,
Ten years ago i was a field service controller for one of the biggest IT companies in GB.
Most of our junior engineers went on the Cerco training and ALL went on to get great jobs and even in later years start up their own IT/Engineering consultancies.
Cerco is the DB's. it is expensive but recognized in the industry as a feather in your cap.
If you take your career seriously then go for it, if you work for a company try and get them to pay (you will find they will ask you to sign a contract to stay with them for poss 3 yrs but it will be worth it).
Hope this helps and good luck.
