The 14-year-old Modern Family actress will start classes at a private school in Los Angeles later this month, according to TMZ.
Sources close to the star say she "can't wait" to begin classes, after previously being privately tutored at home.
Modern Family producers are said to be "thrilled" at Winter's new schooling plans, and will schedule filming around her classes.
Winter was recently placed under the temporary guardianship of her sister Shanelle Gray until March, after she was removed from her home following allegations that her mother Chrystal Workman had physically and emotionally abused her.
Producers of the ABC sitcom have reportedly noticed a "positive" change to Winter's mood since she moved in with her sister.
Winter's father Glenn Workman has been given control of his daughter's finances, which are said to include around $75,000 per Modern Family episode.
