Purpose: The purpose of the study is to identify barriers to collaboration among female administrators at a Ghanaian technical university (TU), based on the social identity theory (SIT). Design/methodology/approach: A mixed-method approach was adopted, integrating qualitative interviews of 15 female administrators and completing structured questionnaires from 117 randomly sampled female administrators. The SIT, as the analytical framework, identified themes emerging from the data on barriers to collaboration among female administrators. While exploratory factor analysis identified measures of factors hindering collaborations, the use of structural equation modeling (SEM) enabled the confirmation of relationships among the barriers to collaboration with female administrators. Findings: There existed statistically significant relationships between four of the barriers: intergroup relations conflict, trust with stakeholders and among females and structural barriers (SBs). For the quantitative analysis, it was found that SBs, intergroup relations, conflict and trust were statistically significant except for weak cultures. For the qualitative, results showed that SBs, lack of trust with stakeholders and among females and intergroup conflict hinder collaboration. Research limitations/implications: The study has a limited scope in using only one TU and focusing on a particular gender. The implications of this research will enrich the literature on barriers to female administrative collaboration in technical education based on the SIT. Practical implications: Promoting administrative collaborations in the TU will ensure sustainability and efficient administrative systems. Social implications: Institutional policies should include gender inclusivity and equality on networking opportunities and provide mentorship programs for efficient administrative systems. Originality/value: We used the SIT to determine barriers to collaboration among female administrators in a technical education institution, and the mixed methodology added a unique dimension to the study.
