Smart was held captive for nine months after being abducted from her Utah bedroom by Brian D Mitchell and Wanda Barzee when she was just 14 years old.
It was only after police recognised Smart in the company of Mitchell and Barzee in Sandy, Utah that the young girl was rescued and reunited with her family.
Nearly a decade after her kidnapping, Smart has inked a deal to provide insight on missing children cases for ABC's morning programme Good Morning America.
An ABC rep commented to The Daily Beast that Smart's primary role will not involve retelling her own personal story, but she will instead assist viewers in understanding "missing-persons stories from the perspective of knowing what a family experiences when a loved one goes missing".
Smart will not be a regular contributor to GMA, but will make appearances on the morning show and possibly Nightline when child abduction cases are in the news.
The now 23-year-old has become an advocate for missing children in the years since her rescue, even lobbying the US Congress to enact Sexual Predator Legislation in 2006.
Earlier this year, Smart was one of four women to receive the Diane von Furstenberg Award and has vowed to use her $50,000 (£31,310) prize to start a foundation to help children deal with traumatic events.
