As you asking I am telling National Council of State Boards of Nursing conducted Computerized Adaptive Testing (CAT) as a method for administering exams that merges computer technology with modern measurement theory to increase the efficiency of the exam process.

CAT is apply for the NCLEX because it:
• Reduces the number of "easy" items that high-ability candidates receive; "easy" items tell little about a high performing candidate's ability

• Reduces the number of "difficult" items low-ability candidates receive; candidates tend to guess on items that are too difficult which can skew results
• Reduces item exposure and subsequent security risks

• Improves precision of measurement of the NCLEX candidate's ability related to nursing and

• Provides a valid and reliable measurement of nursing competence

CAT Definitions
• Candidate ability - The level of entry-level nursing knowledge, skills and abilities that the candidate has.

• Ability estimate - The level of entry-level nursing knowledge, skills and abilities that the computer has determined that the candidate has.

• Passing standard - A cut point along an ability range that marks the minimum ability level requirement. For the NCLEX, it is the minimum ability required to safely and effectively practice nursing at the entry-level. Learn more about the passing standard here.

• Logit - A unit of measurement to report relative differences between candidate ability estimates and item difficulties.
