Flocks and troops are guided by volunteer leaders and divided by age group:
- Littlebirds: Kindergarten (age 5-6) girls and boys (boys may join Cub Scouts in Grade 1).
- Bluebirds: Grades 1-3 (age 6-9)
- Girl Guides: Grades 4-6 (age 9-11)
- Senior Girl Guides: Grades 7-12 (age 11-17)
Flocks and troops meet weekly, biweekly, or once or twice monthly, depending on what works best for our volunteer leaders. Groups that meet at school generally meet for one hour right after class is released so that bus riders can ride the ES Activity Bus home.
The flocks and troops that meet at ISB, along with the flocks and troops at other international schools around Bangkok, form GGAT's International Division.
