This study aimed at investigating the aberrant response patterns and their impacts on the Jordanian version Otis- Lennon as well as the accuracy in the estimation of a person's' ability and information function test.  To achieve this goal, the Jordanian version of  the Ability Test primary II level form K was administrated to 568 first-grade male and female students of Ajloun district public schools during  2016/2017. The Lz person fit index and the three-parameter  logistic model were used to analyze students' responses to test items to assess the person ability, information function test, and to detect aberrant response patterns. The results revealed that the response patterns of 56 students were aberrant based on Lz index; also the results showed that the factors responsible for the presence of this aberrant response were: guessing, cheating, laziness, and exponential creatively. The results indicated that when the aberrant patterns were excluded, both the accuracy person's estimating ability and the information function test had significantly increased at different ability levels.
