Modules can be delivered in short or long formats

Each module can be delivered in formats of 3 hours a day, or 1.5 hours a day. Importantly, our modules are carefully designed to ensure that even in the 3 hour format, children have a maximum exposure time of 2.5 hours total screen time per day, with a limit of 40 minutes in any one continuous block.
