What is junior kindergarten?

Junior Kindergarten (JK) is a pre-school program that typically serves children aged four years old. It's a step between preschool and senior kindergarten (SK) or kindergarten, bridging the gap before formal schooling begins. The curriculum focuses on play-based learning and social-emotional development, preparing children for the more structured environment of kindergarten. The specific curriculum and program structure can vary depending on the country and even the school district.
