Online Course Index

Each course is approved for one point of continuing education or 0.1 CEU. The cost for each course is $25.00.

Select the course you want to take. Pay for the course with your credit card or electronic check.

Each course is divided into four sections. Each section is timed by a clock to fulfill the time requirement for online study by the State of Georgia. Each section is followed by a multiple choice question. If you select the wrong answer you will be asked to try again until you select the right answer. After you have completed all four sections you will receive a certificate of completion. The approval number is listed on the certificate.
