The purpose of this research is to explore the Intentions of adolescents to study and how study behaviour may be influenced by the internal variables of Azjen's Theory of Planned Behaviour, Attitudes to study, Perceived Behavioural Control (PBC) and Subjective Norms. The external variables of Impulsiveness and Grit were also investigated, with a view to discovering any gender differences. A correlational design, using purposive sampling, measured academic motivation through the Theory of Planned Behaviour (Ajzen & Fishbein, 1980; Ajzen, 1990), secondly, Grit using the 8 item Grit Scale for children (Duckworth & Quinn, 2009) and thirdly, Impulsiveness using the 15-item short version for adolescents of the Barratt Impulsiveness Scale (Fossati, Barratt, Acquarini, & Di Ceglie, 2002). This study found no gender differences between variables, with the exception of Indirect Attitude. Grit, measured was not found to be significantly correlated with Academic intentions, contrary to previous research. A significant correlation was found between academic intentions and Impulsiveness.
