In Australia, 3-year-old kindergarten programs, also known as pre-kindergarten or preschool programs, typically run for a minimum of 15 hours per week, spread over two to three days. However, the exact hours and days of the week may vary depending on the specific kindergarten program and location. Some kindergartens may offer longer hours or additional days to meet the needs of working families or to provide additional educational opportunities for children. It’s best to check with your local kindergarten program for their specific hours and schedule.
