Is the current test easier or harder than past or future tests?
Because of NCBTMB’s commitment to quality and test security, there are multiple forms of NCBTMB tests being administered in the field at any given point in time. While these different test forms were developed from the same set of content specifications within each testing program, the level of difficulty associated with an individual test form may vary slightly because different questions appear on different test forms. Since it would be unfair to require a candidate taking a slightly more difficult form of a test to answer as many questions correctly as a candidate taking an easier form of that test, a statistical procedure known as equating is used to correct for differences in test difficulty. Please note that the passing standard for the tests is consistent for all test takers within a testing program, regardless of the test form that is administered to them.
