Purpose: This paper aims to investigate how graduates' perceptions of self-service technology and perceived job performance can be used to assess university service quality. Also, this study examines the mediating role of perceived job performance on the effect of university service quality on graduates' satisfaction and loyalty. Design/methodology/approach: A quantitative methodology was adopted where university graduates' perceptions of self-service technology and job performance were used to assess the level of the university's service quality. Through a cross-sectional survey, data were collected from 280 university graduates employed in Chinhoyi town, Zimbabwe, during the period between August and December 2021. Findings: This study's findings indicate that self-service technology influences university service quality which in turn impacts on graduates' perceived job performance, satisfaction and loyalty. Graduates' perceived job performance was also found to partially mediate the effect of university service quality on satisfaction and loyalty among graduates. Research limitations/implications: This study's results are instrumental to enable university's management in developing economies to adopt and improve self-service technologies as this enhances university service quality and graduates' perceived job performance, satisfaction and loyalty. Originality/value: This paper provides new insights, that is, the incorporation of graduates' perceptions of self-service technology and job performance in assessing the university's service quality. This research further clarifies the function of graduates' perceived job performance in mediating the effect of university service quality on graduate satisfaction and loyalty. This study further adds to our understanding of tools, criteria and methods for assuring university service quality. [ABSTRACT FROM AUTHOR]
