Metro Nashville School Board members voted to send kids to school on the day of the Great American Eclipse, August 21.
The board made the decision to change the calendar Tuesday night.
Students were originally scheduled to not be in school with the day being considered as a professional development day for teachers.
However, that day was moved to a different month, allowing teachers to use the eclipse as a teaching opportunity on something that hasn't happened for 99 years.
School officials said they were still working out the details of how to incorporate the eclipse into the school day.
Parents will be given the choice of sending their child to school or keeping them home for any planned eclipse activities they may have already made. Officials said students would not be penalized for missing the school day.
