In the Netherlands, students learn about sexuality gradually, starting as young as age four. This expansive sex-ed model has been credited with some of the world’s best outcomes for teen sexual health. Known as ‘Spring Fever’, the programme is centred around a week each March in which students learn about sex, love and relationships in a ‘shame-free’ environment. This documentary from the UK filmmaker Anna Snowball follows a group of pre-teens during Spring Fever as they attend lessons, engage in open discussions and submit anonymous questions for their teacher to address. Alongside an introduction to the Dutch system of comprehensive sex education, the film offers a charming window into to the awkward adolescent years – and all the giggling, camaraderie and self-discovery they entail.
