Webinar Instructions
Each webinar session earns continuing education credit and can be registered for individually. All attendees must log-on through their own email – attendees may not watch together if they wish to earn continuing education credit. HalfMoon Education Inc. must be able to prove attendance if either the attendee or HalfMoon Education Inc. is audited.

Certificates of completion can be downloaded in PDF form upon passing a short quiz. A link to the quiz will be sent to each qualifying attendee immediately after the webinar. The certificate can be downloaded from the Results page of the quiz upon scoring 80% or higher.

Webinars are presented via GoToWebinar, an easy-to-use application that can be run on most systems and tablets. Instructions and login information will be provided in an email sent close to the date of the webinar. It is highly recommended that you download, install and test the application before the webinar begins by clicking on the link in the email.

Continuing Education Credit Information
This seminar and webcast are open to the public and are designed to qualify for 7.0 PDHs for professional engineers and 7.0 HSW continuing education hours for landscape architects in Missouri, and most other states that allow this learning method. Please refer to specific state rules to determine eligibility. 

The Missouri Board does not pre-approve engineering courses or activities; it is up to the licensee to determine what activities are appropriate. 

The Landscape Architecture Continuing Education System has approved this course for 7.0 HSW PDHs. Only full participation is reportable to the LA CES. 

This course has been approved by the Association of State Floodplain Managers for 7.0 CECs for floodplain managers. 

The webcast format of this course has been approved by the Practicing Institute of Engineering for 7.0 PDHs in the fields of engineering, landscape architecture and geology. This approval is appropriate for professionals licensed in New York. 

This course offers 7.0 PDHs to professional geologists in some states. HalfMoon Education has not applied for state geologist continuing education approval in states requiring such. 

Attendance will be monitored, and attendance certificates will be available after the webinar for those who attend the entire course and score a minimum 80% on the quiz that follows the course (multiple attempts allowed; only required for online attendees). 

 

On-Demand Credits
The preceding credit information only applies to the live presentation. This course in an on-demand format may not be eligible for the same credits as the live presentation; please consult your licensing board(s) to ensure that a structured, asynchronous learning format is appropriate. The following pre-approvals may be available for the on-demand format upon request: 

7.0 HSW PDHs (LA CES) 

7.0 CECs (ASFPM)
