Tennessee does not specify an age that a child can legally be left home alone.
Illionis (age 14) and MD (age 8) are the only two states, that I am aware of that have these requirements.
This is what Children Services in TN says on its website about the issue
There is no legal age for children to stay at home alone. Parents are advised to use their best judgment, keeping the child's maturity level and safety issues in mind. Younger children have a greater need for supervision and care than older children. Obviously, young children under age 10 should not be left without supervision at any time. In most cases, older teenage children may be left alone for short periods of time.

Keep in mind, that TN does have child neglect and reckless endangerment laws that could apply, in the event that something unfortunate should happen to the children, absent adult supervision.
