The New Membership Grade Levels Girls say it is important to be with other girls their age and, currently, they get bored by too much repetition. As one 13-year-old Girl Scout wrote, “It makes us more comfortable to be with the same age group as ourselves.” Girls identify with social groups based on grades. Research also found that girls learn best and have the most fun when they are with the right developmental/social grouping. The new grade levels, approved by the National Board, address the charge of intentionally creating differentiated Girl Scout experiences that mirror girls’ developmental needs: Girl Scout Daisy, Grades K-1 Girl Scout Brownie, Grades 2-3 Girl Scout Junior, Grades 4-5 Girl Scout Cadette, Grades 6-8 Girl Scout Senior, Grades 9-10 Girl Scout Ambassador, Grades 11-12 The grade-level groups provide "leadership levels" for girls as they progressively "step forward" through the New Girl Scout Leadership Experience.
