New Zealand has increasing rates of anxiety with 1 in 5 young people meeting the diagnostic criteria for an anxiety disorder by the age of 19 (Ministry of Health, 2018). As of June 2023, over 666,000 children aged between 5 and 14 years old were diagnosed with anxiety, equating to 12.8% of the total population of New Zealand (Stats NZ, 2022). As these children are likely to be engaged in formal education, this study investigated teachers understanding and management of students with anxiety in New Zealand primary schools. Twenty-three teachers from three primary schools completed a questionnaire exploring their definitions of anxiety, the training and support they received, and their identification of the manifestations of anxiety in primary school students. Teachers were also asked about their perceptions of the impacts of COVID-19 on student anxiety. Results revealed that while teachers had a general understanding of anxiety and could identify mild and severe anxiety symptoms, they reported a lack of training and confidence in the area and could not consistently distinguish normal anxiety from excessive anxiety, often defining all anxiety to be a generally negative experience. This study provides a first look into teachers understanding of anxiety in New Zealand primary school students.
