The Teen Advisory Group (TAG) started in the Western Cape province of South Africa in 2008 with the aim to engage with adolescents and young people (AYP) as co-creators of social science research, and develop AYP-informed policy and programming recommendations. In 2018, the Accelerating Achievement for Africa’s Adolescents Hub conceived of and planned the establishment of TAG groups in Kenema, Sierra Leone and Entebbe, Uganda. In 2019 these expanded to the Eastern Cape, and in 2020 to Kisumu, Kenya.
