DISCLAIMER
Before undertaking any on-demand effort, you should review the rules of your licensing/certifying entity.
It’s your responsibility to determine whether this on-demand course meets your continuing education requirements.
You must take and pass a quiz to receive credit. You can take the quiz as many times as needed and there is no time limit on the quiz.
Once the quiz is completed, you will be asked to download your certificate.
**Any on-demand programs that qualify for AIA or LACES credit will require an additional 2 business weeks for processing.
**AIA credit is not available in USB format.
Streamable MP4/PDF
You will receive an automated email letting you know when your On-Demand package is available approximately 3 business days after the date of the live event or the date of your order, whichever is later. This email will contain links to the video recording, materials, and program quiz.
To track your purchase, you will need to create an account on the website using the email address used for your registration.
For AIA requirements only, the on-demand recording will have occasional question prompts that will not allow the video to progress unless they are answered, and you will not be able to skip forward while watching the video.
Please note, if you attempt to resume watching the video on a separate device, your progress will not be saved.
Click the link which appears at the end of the video to be taken to the course quiz.
You will have unlimited access to the on-demand video recording, and it will never expire.
**Any streamable on-demand programs that qualify for AIA or LACES credit will require an additional 2 business weeks for processing.
USB MP4/PDF
HalfMoon will mail these materials via USPS.
USB orders ship approximately 3 business days after the program takes place or after the order is placed, whichever date is later. Please allow an additional 7-10 business days for shipping.
The link to the quiz will be available in a PDF in your USB drive marked QUIZ.
HalfMoon will contact you and issue a full refund if the product you ordered is not available. However, refunds will not be issued if completion certificates are requested.
Please contact HalfMoon Education if you have any questions during the process of taking this course. (715) 835-5900 or qchapman@halfmoonseminars.org
