Best Cert for Cable Installer / Testers

flipmad

My company is getting into contracts to run wiring and test for customers. I already have experience running cabling, punch downs, etc. But what would be the best cert to supplement this experience and help us grow in this field?

My co-worker is an RCDD through BISCI (https://www.bicsi.org/default.aspx) and he seems to have learned a lot from their training. I have heard a few people talk about their cable installer training as well. Anyone else have any input on this? This something I have been considering learning as well.
