马里兰州最大的学区之一正在寻求最高级别的帮助，以解决其公共汽车司机短缺由...带来的奥米克隆激增。

蒙哥马利县公立学校要求县官员敦促该州部署国民警卫队，并让他们驾驶该地区的校车。

Cram told ABC News the state hasn't responded to the school district's request as of Wednesday evening.

Montgomery County's request is among some of the extraordinary moves that school districts have made to fill staffing shortages caused by the ongoing COVID-19 pandemic.

On Wednesday, the Kansas Board of Education voted on a measure tochange the requirementsfor hiring substitute teachers.

Anyone over 18 who has a high school diploma and passes a background check can apply to be a substitute teacher. The new regulation will remain in effect until June, officials said.

School districts in Palo Alto, California, and Hays County, Texas,have also reached out to parentsto help fill the shortages caused by sick substitute teachers and other staff.
