This study attempted to look into the leadership style of college administrators and its association to organizational effectiveness. Likert leadership theory was adopted in the study to describe the leadership style of college administrators in planning, organizing, leading, and controlling. The organizational effectiveness of college administrators was measured in the areas of expansion program, faculty development and student development.

The respondents were 289 faculty members and 273 student leaders, while 18 college administrators served as the subject-respondents of the study. They were chosen through purposive-random sampling from the city and province of Iloilo. The investigator obtained data through a questionnaire-checklist and open-ended form administered to the respondents of the study. Data results were subjected to statistical treatment for analyses employing percentage, mean, standard deviation, t-test, one-way ANOVA, Kruskall-Wallis, Mann-Whitney U, Pearson r, and stepwise multiple regression.
