Abstract

Background: Teacher performance is closely linked to instructional quality, and school leadership may shape it through academic supervision and managerial practice. Objective: This study examines whether academic supervision and the principal’s managerial competence are associated with teacher performance at SMA Negeri 1 Soreang. Methods: A quantitative correlational survey collected 1–4 Likert-scale responses from 19 purposively selected teachers. Descriptive statistics, assumption tests, correlations, and simple and multiple regression analyses were conducted using IBM SPSS Statistics 29. Results: Academic supervision explained 76.4% of the variance in teacher performance, while managerial competence explained 72.2%. Their joint model was significant (F = 25.970, p < .05) and accounted for 76.4% of the variance. Because the two predictors were highly correlated, partial findings are interpreted cautiously. Conclusion: Teachers appear to experience supervision and managerial leadership as interconnected features of principal leadership. Schools should strengthen classroom-focused supervision, feedback, and managerial support as complementary improvement practices.

Abstract

The increasing demand for high-quality learning services in higher education is often not matched by institutional readiness to develop supportive academic ecosystems and manage change effectively, creating a gap between student expectations and actual service quality. This study examines the effects of the academic ecosystem and change management on learning service quality at the postgraduate level in response to the growing expectation that universities function as service-oriented institutions. A quantitative survey was conducted involving all 95 postgraduate students enrolled in the Educational Administration Study Program, Faculty of Education, Universitas Pendidikan Indonesia. Given the relatively small population, a census sampling technique was employed, with all students included as respondents. Data were collected through questionnaires and analyzed using multiple linear regression after meeting the classical assumption tests. The results indicate that the academic ecosystem and change management have positive and significant effects on learning service quality, both simultaneously and partially, with a combined contribution of 49.9%. The academic ecosystem exerts a stronger influence (β = 0.479) than change management (β = 0.327). These findings suggest that strengthening academic ecosystems and implementing sustainable change management are essential for improving learning service quality and enhancing institutional competitiveness in higher education.
