The purpose of this study was to examine the factors influencing professional judgment of Malaysian auditors. A questionnaire was used to measure the level of professional judgment and factors influencing the judgment such as gender, knowledge, position level, experience and also firm size. The multiple regression results showed that the position level and experience to be statistically significant in determining the level of professional judgment of auditors. Gender, knowledge and firm size have no significant relationship with professional judgment. As for gender, past research has shown mixed results and this study proves that there is no gender differences among Malaysian auditors in terms of their professional judgment. Even though past research has shown that knowledge has a positive relationship with professional judgment, this study finds no significant relationship between the two variables. With regard to firm size, this study finds similar results of prior study that there is no significant relationship between firm size and judgment. In terms of the practical implications, this study provides insights into significant factors that influence professional judgment of Malaysian auditors. Besides, the management of audit firms can place emphasis on establishing training to their employees especially for the junior staff. Exposing junior auditors at the early stage might improve their professional judgment when facing with complexities of assignments.
