They still teach swimming in primary school BUT how often is both determined by budget and if the staff see it as worth while. At least it can be just for one term per year (5/6 weeks), which, though better than nothing, won't really turn none swimmers into compitent swimmers, especially for open water. Same with senior school, at my daughters school, swimming isn't on any sports curriculum, so if the kids were struggling in primary, they've got no chance there...
It's a travesty for what is a life skill...
