When do classes start and end during the school year?
It depends on the school: each school has its own calendar, adjusted to its own schedule. You can see the start date for your group on the registration form and in the family portal once registered.
As a general rule, the activity follows the school’s academic calendar, including its holidays and non-school days.
If you have questions about a specific date, ask through the family portal chat: your group’s instructor has the exact calendar.
