Q: How does the Shelby snow day predictor work?

It reads the National Weather Service forecast for Shelbyville through the night and the 5 to 8 am bus run, adds winter alerts and the Winter Storm Severity Index, and measures the snow against Shelby’s own big snow morning: 2 inches, the top tenth of snowy weekday mornings at a NOAA weather station 18.8 miles away.

Q: Can Kentucky schools hold a remote day instead?

A district with a Commissioner approved NTI plan may count up to the equivalent of 10 student attendance days when it closes for health or safety reasons.

The Kentucky rule

How Kentucky counts a lost day

Kentucky requires at least 1,062 instructional hours on at least 170 student attendance days. After an emergency a board may amend its calendar and lengthen or shorten the remaining days by 30 minutes or more, as long as the year still meets the requirement.
