This research ascertained the influence of administrator and teacher performance and the students academic achievement on organizational effectiveness. Conducted in December 1998, the participants of the study were the 24 academic unit heads, 82 college faculty and 450 college students as Central Philippine University. The proportional random sampling method was employed. This descriptive-correlational research utilized three data-gathering instruments: the UPLB's Rating Scale for Higher Education (Ables, 1996), the CPU's Teachers Rating Scale, and the Effective Work Group Checklist. Raw scores, means and standard deviations were employed as descriptive statistics and the t-test for independent samples, the One-way Analysis for Variance, and the Pearsons r set at .05 alpha level as inferential statistics. Results revealed that, generally, the academic administrators had "very satisfactory" performance as assessed by the faculty. Generally, the faculty's teaching performance was "very good" based on the students evaluations and the students achievement was "good"." CPU as an organization was considered "very effective" among the administrators, faculty, and students. The administrators differed significantly in their administrative performance grouped according to college affiliation. Significant differences existed in the students academic performance grouped according to sex and college affiliation. The students differed significantly in their perception of organizational effectiveness grouped according to high school of origin and college affiliation. No significant correlations existed among administrative and teaching performance, students academic performance, and perception of organizational effectiveness. Sex and high school of origin were significant predictors of the students academic achievement.
