There was a series of articles on stairs in "Building Standards Magazine"
several years ago that might address sloping of stair treads. This, I
believe, is more critical than floor flatness in a school situation as a
tread sloping to the nosing tends to throw a person forward.
The common specification for floor flatness years ago was a deviation of not
more than 1/8" from a 10-ft. straightedge.
