The effectiveness in managing these factors determined by how well his/her leadership styles. Unfortunately, there is no single leadership style that can be regarded as the most effective in any situation. This study exercise an idea to examine the reliability and validity of the instruments – called STRQ Leadership Styles Questionnaires - that can be used to measure and describe 3 leadership styles -e.g. Visionary, Transformational and Transactional styles The instruments consisted of 2 form questionnaires: (1) Self-Rating Questionnaire (SRQ) used by a principal to make self-assessment of his/her leadership style, and (2) Teacher-Rating Questionnaire (TRQ) used by teacher to make assessment of his/her principal’s leadership style. The instruments used the Pair-Comparisons Method which consisted of 18 pair-statements that derived and formulated from indicators of each leadership style. In this study, The SRQ applied to 113 middle secondary school (SMP) principals in Bogor City, and the TRQ applied to 226 teachers (each school principals assessed by 2 teachers). The reliability of SRQ derived from the consistency of principal self-assessed his/her leadership styles which achieved of 0.82 level of consistency. The reliability of TRQ derive from the correlation between scores of the First Group (113 teachers) and the Second Group (113 teachers) which achieved of average coefficient 0.87 calculated by Pearson’s PM Correlation. The validity of STRQ Leadership Styles Questionnaires derived from calculation between SRQ and TRQ scores, which achieved of average coefficient 0.83. The findings of this study mentioned above can be concluded that the STRQ Leadership Styles Questionnaires have highly level of reliability and validity in assessing the leadership styles of Visionary, Transformational and Transactional.
