Clinical certified nutritionists help make people healthy from the inside out.

Nutritionists provide services to help maintain the health of patients by overseeing eating habits and correcting improper nutrition consumption, according to the U.S. Department of Labor. Clinically certified nutritionists undergo extensive training and certification to provide factual information to patients who need to alter their diet due to health complications. Every state features unique requirements for nutritionists; however, most states demand nutritionists have a bachelor's degree, certification and licensure as well as registering with local organizations, according to the U.S. Department of Labor.

Acquire at least a Bachelor of Science degree (BS) from a nationally accredited university. Your major should align with the nutrition field or a related field. The Clinical Nutrition Certification Board examination, which is given by the nation’s leading nutritionist certification board, requires at least three course hours in chemistry, microbiology, anatomy/physiology, biochemistry and human biology in order to apply for the certification program.

Complete and submit the Credential Review Application to the Clinical Nutrition Certification Board. As of 2010, this application requires a $75.00 fee, as well as two official transcripts from any university you attended, in order to gain your degree. Along with the fee, you must include an application letter requesting transcript review, three reference letters and two photographs of your face.

Access the online course study materials provided by the Clinical Nutrition Certification Board after your Credential Review Application has been approved. You must complete a total of four Post Graduate Studies in Clinical Nutrition Online Progress Access (PGSCN) sessions, each costing $1,125 as of 2010, in order to proceed to the actual examination. Each session must be completed within 90 days after you begin.

Pay the $450.00 (as of 2010) examination fee when you send off the examination application to the Clinical Nutrition Certification Board. After approval, the board will schedule a testing date. Once you pass the exam, you will be a nationally certified nutritionist.

Things Needed

  • ['Bachelor of Science – minimum degree requirement', 'Credential review application and fee ($75.00 as of 2010)', 'Official university transcripts (two copies)', 'Application review letter', '3 reference letters', '2 face photographs', '$1,125 PGSCN fee (as of 2010)', '$450.00 examination fee (as of 2010)']


  • Speak with the Clinical Nutrition Certification Board to determine if further testing is required in order for you to operate as a clinically certified nutritionist within your state.


  • Do not simply skim over the study materials within the PGSCN sessions, as the examination will pull from information from each of the four sessions.
