Discuss about the Luria Nebraska procedure

The Luria Nebraska procedure involves an age and education correction. It is accomplished by computation of a cutoff score for abnormal performance based on an equation that takes into consideration both age and education. The computed score is known as the critical level and is equal to .214(Age) + 1.47 (Education) + 68.8 (Constant). Typically, a horisontal is drawn across the profile at the computed critical level point. The test user has the option of considering scores above the critical level, which may be higher or lower than 60, as abnormal.
