I recently went through the BD&C eligibiliy requirements for a coworker and the latest pdf (http://www.gbci.org/main-nav/professional-credentials/resources/candidat...) says

"This work experience must be documented through LEED Online* or in the form of a letter of attestation from a supervisor,..."

"*In order to verify project participation through LEED Online, please submit a screenshot which captures the project name and date, as well as your name and your access to/role within the project."
