"Exams for the LEED Green Associate, BD+C, ID+C and O+M will feature v4 content in June. Exams for Homes and ND will feature v4 content in 2015."

When exactly in 2015 will the v3 accreditation examination end for ND? As in, is there a specific month and date?

I ask as my employer has the v3 reference guide, but if the switch is early in 2015 then I'll need to buy v4 study material myself, as they are not going to do so.

Your input would be appreciated!
