Thanks. I read through some of the requirements and stopped when they became overloaded. They are so onerous, I don't see how any school system could get anywhere near meeting these requirements. Even before they get to school, the bus requirements can't be met. My comments are in bold.
Buses
Encourage alternative modes of transportation for students who have other safe options, including walking or biking.
Before the bus driver starts their route, how do they know who's going with them or not and who they're picking up? Who decides who has to take other transportation? Ideally, for students riding the bus, symptom screening would be performed prior to them being dropped off at the bus stop.
WHo checks the kids before they get on the bius? How? Where?Having bus drivers or monitors perform these screenings is problematic, as they may face a situation in which a student screens positive yet the parent has left, and the driver would be faced with leaving the student alone or allowing the student on the bus.
What do the bus driver's do?Assigned seating; if possible, assign seats by cohort (same students sit together each day).
What happens when the bus reaches it maximum load about half the usual kids? Does the driver go home? What are the rest of the kids who have not been picked up suppose to do?Tape marks showing students where to sit. Buses onormally pick up full loads.
What happens to the other half of kids?Face coverings should be worn at all times, particularly if 6 feet distance cannot be maintained.
Is the bus drivers suppose to control the kids and drive too? I can imagine what's going to happen the first time a driver is distracted and runs his bus into a telephone pole and kills three kids. Drivers should be a minimum of 6 feet from students; driver must wear face covering; consider physical barrier for driver (eg, plexiglass).
Minimize number of people on the bus at one time within reason.
See above question about half loads.
Consider altering start and end times at different grades to allow fewer students on the bus at a time.
How does this happen?Adults who do not need to be on the bus should not be on the bus.
Have windows open if weather allows.
Ensure adequate cleaning of buses between uses.
The logistics seem impossible. The rules once the kids get to school are similarly draconian. How do you run half classes? I see why teachers are complaining that it's an impossible task they're being asked to perform. MAybe the solution is the internet from home. I don't know. Is anyone sending their kids to school? How are they handling it? Maybe there are other more practical solutions.
