Pursuant to the authority of Iowa Code sections 147.34 and 153.39, the Dental Board hereby gives Notice of Intended Action to amend Chapter 22, "Dental Assistant Radiography Qualification," Iowa Administrative Code.

The amendment sets 50 as the minimum number of questions for the examinations, specifies that the examinations must be administered in a proctored setting, and sets a minimum pass rate of 75 percent or better.
