UPDATE: The Mojave Unified School District canceled classes Friday at all six schools due to what's being called a "significant staffing shortage in key departments."

Dr. Katherine Aguirre, the district superintendent, told 23ABC the Transportation Department was heavily impacted. Aguirre said more than 90% of students in the district ride the bus and there weren't enough drivers, even calling in backups, to get the kids to class.

The district is working with the Kern County Superintendent of Schools office for additional resources to prevent future closures. But right now numbers are limited.

They're asking parents to bring kids to school on Monday while looking for outside contractors. But there's a chance the closure could extend into next week.

Mojave Unified School District said on Facebook they are canceling classes for Friday, Jan. 28th, due to staffing shortages.

The school district said in the post that they are working with the county to try to prevent future closures. They also said the closures could extend into next week.

The district includes six schools: California City High School, California City Middle School, Hacienda Elementary school, Mojave Elementary school, Mojave Junior and Senior High, and Robert P. Ulrich elementary.
