Hi Matthew, as a LEED AP, your credential is more advanced than a LEED Green Associate.

You may do nothing and call yourself a LEED AP. There should be no reason to take the LEED Green Associate exam, unless you're a rich masochist.

You may be confusing LEED Green Associate with LEED AP+. LEED AP+ is the new "with specialty" title for LEED AP and carries with it the specialty designation of your focus area (such as Operations and Maintenance, Building Design and Construction, Interior Design and Construction, etc.)

New LEED System

For existing LEED APs, you may become a LEED AP+ (plus specialty) by enrolling in the new tiered 2009 system.

To do this you must agree to the LEED 2009 Credentialing Maintenance Program (CMP), sign the Disciplinary Policy and complete the prescriptive CMP requirements for the initial 2-year reporting period.

Once you have become a LEED AP+, you will use one of the new specialty suffixes (O&M, BD&C, ID&C) after your name. Enrollment must occur before June 2011.

Other Enrollment Options

You may also make the transition to LEED AP+ by passing one of the new specialty examinations, called the Tier II exam.

Only the Tier II LEED AP+ exam will be required if testing by June 2011. Same rules apply here as described in the paragraph above.

Legacy LEED APs

As a current LEED AP, you may choose to do nothing and you will continue to be designated a LEED AP in the LEED Professional Directory.

If you choose to make the transition by choosing #1 above there are no fees to become a LEED AP+ if you enroll in the CMP between June 30, 2009, and June 30, 2011.
