The first floor of my classrooms are slab on grade which per the LEED template should have an STC of 50 because its ajacent to the outdoors (grade being the outdoors). My slab is 4" thick and a 4" thick concrete panel has an STC of 49. Should I change my space adjacent to Assembly column to other (as I am adjacent to the earth) and put the required STC at 0?

STC is only valid for occupied spaces. There is no adjacent space beneath a slab on grade. You do not need to input "outdoors" for beneath the building and can leave it blank.
