National Nurse Competency Benchmark Index (NNCBI) uses data from an extensive database of online competency exams and behavior assessments to establish percentile-based benchmarks for nurse exam scores.

NNCBI's statistical analysis will provide employers with an objective measurement of how a given nurse's performance compares to that of nurses from across the nation during the previous year.

NNCBI National Percentile Color Legend

NNCBI's rankings and the color scale on the above graphs are based on the percentile in which a nurse scores. For example, on the Medical/Surgical exam, a score of 91 is higher than 55% of the scores for that exam, so a nurse scoring a 91 is in the 55th percentile. Raw score combined with percentile placement gives an objective view of how a nurse has performed on the exam or assessment when compared with all nurses being similarly assessed across the nation.
