Authoritative leadership style
This style is indicated by a low communication level. Principals using this style spend at most 33.3% of their time per week communicating with the students, teachers, parents and community. Out of the 183 USA schools investigated in the TIMSS data, 56 schools were found to have authoritative principals based on this criterion. Those principals exercised their decision and informative role more than their interpersonal role. Table 2 (Appendix) shows a summary of descriptive statistics of the communication level of the authoritative leadership style principals.
