The Timebound program was developed to respond to the education needs of child laborers and those at risk of engaging in the worst forms of child labor. The program established community learning centers in the 10 Time Bound districts of Tanzania. IDD created an interactive radio instruction (IRI) series called Mambo Elimu that reached approximately 10,000 children with no access to formal education. In addition to teaching literacy and numeracy, the programs enabled students to learn important life skills related to health, hygiene, nutrition, and HIV/AIDS prevention. Upon completion of fourth grade, children were assisted in integrating back into the formal school system or to a vocational program.
