Objective: This study investigated how school counsellors in international schools in Hong Kong supported the wellbeing of students and families during the period of school closure caused by the COVID-19 pandemic from the perspective of parents. Method: Sixteen parents with children in eleven different international schools in Hong Kong were interviewed and the data were analysed thematically. Results: Strong pre-existing relationships, role clarity, and open communication between counsellors and parents were associated with the effective adaptation of counselling services to the changing needs of parents during the school closure period, but these characteristics were often weak or absent. Conclusions: Parents' perceptions of counselling during the school closure period provide important feedback that schools can use to build more integrated and responsive support services. Counsellors can support students' wellbeing more effectively during crises by communicating their roles clearly, building strong relationships with parents, and helping students to maintain a diverse experience in their schooling.
