As popularity in the NBHWC Board Exam rises, many test prep courses are being created. Please note that NBHWC does not review or endorse any study material, test prep courses, or practice exams/quizzes outside of those listed above. Examinees should use their discretion when signing up for any non-NBHWC sponsored test prep. The NBHWC Approved Training Program you completed, along with the NBHWC Content Outline, should be your main source of learning for exam prep.
