Also included with the program is a handy StudyGlossary. The StudyGlossary contains indexed references to selected key terms in the program which include definitions as well as where to look in the StudyModules to find more information about each entry.

After you complete each StudyModule, there is a multiple choice Post-Test. Simply fill in the Post-Test Answer Sheet and return it to us using one of the following options:

  • Use the postage-paid return envelope
  • Fax your Answer Sheet for faster feedback
  • Email it to for the quickest results

Of course, all program information and Post-Test results are treated with the utmost confidentiality.

Each StudyModule has been separately accredited so you earn Category A credits as you pass each Post-Test, up to 8 with the Digital Breast Tomosynthesis Essentials!

After we grade each Answer Sheet, we send you a StudyProgress Report that includes your Post-Test score and the official notification of the Category A CE credits earned for that Post-Test.

As you complete each Post-Test, you also receive a set of StudyGuidelines which presents detailed explanations of each and every Post-Test question! StudyGuidelines offer additional information not found in the StudyModules and provide you with guidance back to the specific section that you need to study further.

An Answer Key is provided once you achieve a score of at least 75%. If you score below 75%, an additional Answer Sheet is provided, and you are offered another chance at the Post-Test after you study the material further. StudyProgress Reports and StudyGuidelines are sent to you via first class mail, normally within two business days after we receive your Post-Test answers.

You are awarded the final Certificate of Achievement after you earn the Continuing Education credits for all the StudyModules.
