The Tennessee rule

How Tennessee counts a lost day

Tennessee requires at least 180 days of classroom instruction, with a 6.5 hour instructional day. A district that runs a half hour longer than the required 6.5 hour day all year banks the extra time as up to 13 stockpile days, which can cover days lost to dangerous or extreme weather.
