According to the Texas Department of Family and Protective Services, the state does not identify a specific age when it is legal for a child to be left home alone. That decision is left up to guardians, but adequate supervision is expected in order to keep children safe.
The Department of Family and Protective Services offers several items to consider in order to determine if a child is mature enough to stay home alone. Parents and guardians should take into account the level of physical safety within the environment and the child's ability to handle emergencies, such as illness, fire, severe weather and other hazards. In addition, guardians must assess the availability of a responsible adult who is able to intervene, as needed.
