How the “On-Line Course-Taking” Process Works


This course assumes you have a working knowledge of body composition, at least as far as understanding the compartmentalization of lean and fat tissues. Because you are expected to have a baseline understanding of body composition as mentioned above, this course qualifies as Category II CPE.

If you are a dietitian or a dietetic technician, registered through the Academy of Nutrition and Dietetics (AND) and working toward the accrual of continuing education credits through Commission on Dietetic Registration (CDR) program, you are eligible for three continuing professional education (CPE) units toward the maintenance of your license upon successful completion of the course. At the end of the course, click on the "Take the Post-Test" button, take the test, and submit it for grading. Your test will be graded immediately and a printable CEU certificate presented to you.


For each table that shows weights in pounds and height in inches there is a link you can click to see the table in metric measures.  If you experience trouble with this feature, please be assured that the information you need to complete the post-test is within the written text.
If you own or otherwise have access to a BIA machine, you may want to try it out on a friend or other friendly and willing person before you apply it to your clinical practice. During your trial period of using this technology, feel free to email any questions to the author Sheila Miles, Continuing Education Director at Hi-R-Ed Online University .
