Each class is supported by a teacher and teacher aides

ISL's Early Years Department uses hands-on learning experiences and a Play Based learning approach to facilitate learning in Language, Mathematics and different aspects of Science and Technology, Social Studies, Personal and Social Education, Art and Drama. This approach allows each child to learn at their own level and in meaningful ways.

The International School of Lusaka has a weekly Early Years' assembly where the children listen to stories, sing songs and take part in performances.

Maximum class sizes are:

• Nursery – 30 (1:10 adults to children)
• Pre-School and Reception – 22 (1:11 adults to children)
• Years 1 and 2 – 26 (1:13)
