To further test the relationship between the competencies of the accounting students, and their level of readiness for the AEC, a multiple regression model was used. The results in Table 4 show that there is a significant positive relationship between the Capability, Knowledge, Ethical, and Relationship competencies of the accounting students and their level of readiness for the AEC at the 0.01 level. As indicated by R2 of 0.491, these competencies explain almost 50 per cent of the changes in the dependent variable, namely the level of readiness for the AEC. Therefore, Thai accounting students should improve the Capability, Knowledge, Ethical, and Relationship competencies to increase their level of readiness for the implementation of the AEC. The results are consistent with the prior study by Steelyana (2012) who also found a relationship between the competencies of Indonesian accountants and their readiness for the AEC. This consistency arises because all ASEAN countries are aware that they have to improve the readiness of their people for the AEC, especially those employed in the eight professions which will form the core of the free service areas, namely, Engineering,
