The document discusses the evolution and structure of the NCLEX-RN exam. It moved from a paper/pencil test to computerized adaptive testing (CAT) to more accurately assess candidates' abilities. The CAT adjusts question difficulty based on previous answers. The exam continues until a pass or fail determination can be made with 95% confidence, between 75-265 questions. Questions assess various nursing content areas and use multiple question formats. Successful preparation requires building knowledge and managing test anxiety using frameworks like KATTS and the 5 C's. Extensive practice with NCLEX-style questions is also recommended.
