ANCC paused the exam in late August 2026 and restarted it on September 11 with a new outline. The frame held: four domains under the same names, 125 scored items plus 25 pretest items. What moved, against the outline used from December 2021, is the question count in each domain: three questions left Plan and Implement, two went to Professional Role and one to Assess and Evaluate, while Education held steady. The comparison below has the counts.
The topic statements moved too. Professional development is gone. Prior authorization now sits under fiscal health, and patient-generated health data under clinical data interpretation. Disease-specific interventions are listed as a skill rather than knowledge, so expect to be asked what you would do for a condition. Among the safety examples, environment of care has taken the place of safety rounds and root cause analysis.
If your materials predate the switch
Books and question sets written for the 2021 outline keep their value: same four domains. Shift your hours toward the new counts and add the new topics above. Material built on the 2017 outline, with its five Domains of Practice, needs a re-sort. Its headings (Clinical Practice, Communication, Professional Role, Systems/Legal and Regulatory, Education) are not how either recent outline is built, yet AAACN's review questions and its study page still use them. As we read the two outlines, clinical practice chapters feed the first two domains below, communication chapters mostly feed Education, and systems and legal chapters feed Professional Role. A core curriculum text or review book is worth checking against this page the same way before you trust its weighting.
