Continuing Education Credit Information

These webinars offer professional engineers and architects continuing education credits in all states that allow interactive online learning, except Florida architects. Each webinar listing indicates the number of continuing education credits that are available. HalfMoon Education is an approved continuing education sponsor for engineers in Florida, Indiana, Maryland, New Jersey (Approval No. 24GP00000700), New York (NYSED Sponsor No. 35), North Carolina, and North Dakota. HalfMoon Education is deemed an approved continuing education sponsor for New York architects. Other states do not preapprove continuing education sponsors or courses. HalfMoon Education Inc. is approved by the American Institute of Architects as a continuing education provider (Sponsor No. J885). The Floodplain Mapping and Regulation webinars and the HEC-RAS webinars are approved by the Association of State Floodplain Mangers. See each listing for available CECs. Participation and knowledge retention will be verified for these webinars, certificates of completion will be provided, and LUs will be reported to the AIA/CES.


Dr. Gregory H. Nail, PhD. PE

The University of Tennessee at Martin - Engineering Department

Dr. Nail is an associate professor in the Engineering Department at the University of Tennessee at Martin where he teaches a variety of courses including fluid mechanics, hydraulics and hydrology, and hydraulic and hydrologic modeling. He holds a professional engineer’s license based on having passed both the Civil and Mechanical discipline-specific exams. Prior to coming to UT-Martin in 2002 he worked as a research hydraulic engineer for the United States Army Corp of Engineers for 11 years. He is a former member of the Executive Committee of the Tennessee American Water Resources Association, and he has lectured on various HEC-RAS modeling topics at the Annual Tennessee Water Resources Symposium and at other venues. Dr. Nail earned his B.M.E. degree from Auburn University and his M.S. and Ph.D. degrees from Texas A&M University.
