Eligibility: three options
BICSI's handbook defines ICT design experience (needs analysis, site surveys, layouts of spaces and pathways, specifications, bonding design, calculations) and ICT experience (for example lead technician, foreman, ICT project manager). BICSI verifies the experience you claim.

| 2 | Two years of verifiable full-time-equivalent ICT design experience and two years of higher education course work in ICT |

Keeping the credential

How to study
- Plan for at least 150 hours of TDMM study, the minimum BICSI suggests.
- Read a TDMM chapter, then answer practice questions on that topic the same week.
- Drill the numbers (distances, fills, sizing rules, loss values, PoE levels) with flashcards every day.
- Take at least two full timed mock exams of 100 items in 2.5 hours before the real one.
Frequently asked questions
How long does it take to become an RCDD?

Is the RCDD worth it?
It's the best-known ICT design credential, and some project owners require it: the U.S. Courts Design Guide and the U.S. Department of Defense's UFC 3-580-01 both call for RCDD involvement in telecommunications design.
Can I take the RCDD exam online?
BICSI's v15 handbook describes testing at Pearson VUE test centers. Check pearsonvue.com/bicsi for the options in your country.
