The state of Illinois requires all schools, public and private, to provide a minimum of 880 instructional hours to students. This can be done by scheduling the standard 8:30 to 2:50 p.m. school day for 180 days, or, as a private school, we are allowed to determine the length of our instructional day. Since we are in school for slightly longer than the standard school day, we have some "built in time" to take for emergencies, generally for weather-related closures, the well-appreciated "snow day", or for other emergencies, which can include shut-downs of utilities, water, or incidents such as we experienced this morning, a gas leak.
Circumstances Which Cause School Closure
The most common reason for closing school in our area is inclement weather. These conditions are not always easy or accurate to predict, but if driving conditions to and from school are considered risky or unsafe, we will close school. This would include in the event of an excessive amount of snowfall, preventing the street crews from keeping streets clear, or more likely ice and freezing rain, which makes streets slick and is difficult to melt with salt and clear with a plow.
Excessively frigid temperatures can also prompt closing school. The public schools do this to prevent having kids waiting at bus stops, but we do this as well, because there is a risk to transportation in weather like this. The risk would increase if snow or sleet is accompanying the low temperatures.
It is not possible for us to have school if utilities are not functioning. So if water is out, or gas, or electricity, we will cancel classes.
Excessive absences due to illness is also a factor in determining whether the school will be open or not. School, by the nature of the activity, is an easy place to spread germs, and when there are multiple cases of contagious virus going around, the number of students who get sick is high. When that number reaches 20% of our currently enrolled students, we consider closing down to give everyone an opportunity to stay home and get better, and not spread germs while they are contagious.
How Many Days Can We Miss?
We have not reached the maximum at any point during the seven years I've been here. The number of days we've taken for illness hasn't been more than one in the past seven years, except for the closure that occurred for COVID during the last nine weeks of the 2020 school term.
E-Learning, while a possibility, is also a last resort. It is not as effective when it comes to instruction of students, as the test results and research clearly showed following the last pandemic. But if we know or anticipate in advance that it might be several days, it does help make some progress while we are waiting to return to school.
We recognize closures as an inconvenience, to students because it interrupts their learning experience, to teachers because they have a set of specific objectives their students are scheduled to learn during a limited amount of time, and parents, because they have to find child care and make arrangements for their children to be at home when they weren't planning for it. We take all of that into consideration when we look at the possibility of an unscheduled day away from school.
