Teaching requires not only the ability to teach students, but also an understanding of the rules and regulations of
the school environment, the ability to collaborate and cooperate with other education professionals, students and
parents. Personality characteristics are likely to be important predictors of these abilities. Personality research has
experienced the greatest change with the acceptance of the Big Five factor model of personality (John & Srivastava,
1999) which places personality traits into five categories: Neuroticism (anxiety, self-consciousness), Extraversion
(positive emotion, sociability), Openness to Change (independent, curiosity), Agreeableness (compassionate,
cooperative), and Conscientiousness (self-disciplined, dutiful). These new developments have not been reflected in
research on teachers. Singh & Singh (2010) showed that dimensions of personality were found to change
significantly from trial stage to establishment stage. Singh & Singh (2010) measured career stages in terms of
executives’ age and their organizational tenure. In their study executives showed gradual decrement in neuroticism
score throughout the career stage where as there was a gradual increment in scores on extraversion, agreeableness
and conscientiousness throughout the three career stages. This nature of the change in the mean score of the
personality was supported by the characteristics of the career stage of the executives.
