PurposeThis study aims to build a comprehensive model for developing higher education institutes (HEIs) brand equity by examining the impact of HEIs intangible resources, brand management aspects, attachment strength and student’s contemporary citizenship behavior (CCB).Design/methodology/approachData were gathered through a self-administered questionnaire from Indian students and alumni (n = 703). The study examines the proposed comprehensive model through serial and multiple mediation analysis.FindingsThe study unfolded “service quality? brand image? attachment strength? word-of-mouth? brand equity” as the most significant path to develop HEI’s brand equity.Research limitations/implicationsThis study pioneers an empirically validated mechanism for developing brand equity in HEIs, addressing gaps identified by previous studies and offering a theoretical framework that elucidates how HEIs can leverage intangible resources through strategic brand management to foster attachment and influence positive student behaviors, thereby contributing to the development of HEI brand equity.Practical implicationsHEIs need to understand that relying solely on tangible aspects leads to short-lived effects. To maintain a lasting competitive advantage, HEIs should focus on crafting a rich historical narrative, retaining talented faculty and staff and earning respect from the public to build a lasting reputation.Originality/valueThis study develops the mechanism for developing brand equity of HEIs using its valuable, rare and inimitable intangible resources. Along with the introduction of novel constructs like competence, heritage and word-of-mouth to existing study, the proposed conceptual model is premised on the theory of self-congruence, social-exchange theory and CCB.
