Candidates who took the NBDHE in 2020 and 2021 have reached out to DTS expressing concern that the short-form NBDHE offered during the pandemic might be yielding higher failure rates than expected. DTS has conducted psychometric investigations correspondingly, permitting DTS to meaningfully compare the performance of the standard and short forms. These investigations have found no meaningful differences between these sets of forms. To clarify, the DTS analyses show that candidates who attempted the NBDHE later in 2020 have been more likely to fail, regardless of whether they attempted the full-length examination or the shortened form.

DTS suspects that elevated failure rates toward the end of 2020 are the result of candidates who were further removed from their academic studies and corresponding clinical experiences, and have performed less well on the examination as a result.
