COLUMBUS, Ohio — As the deadline for submitting the required school calendar ticks away, the latest on the school year in the Baltimore suburbs continues to loom.

A new school year starts in the fall with the beginning of classes, but many of the district’s 4,500 employees will work until the new school season begins.

The new school schedule begins with the spring semester and ends with the fall semester, when the districts final-year graduation rate will average 88.8 percent, according to a new report from the Maryland Department of Education.

The Maryland Department for Education has estimated that the median income for Baltimore County residents is $50,800 and the average household income for all residents is more than $75,000.

As of September, the average annual cost of living for the area is $27,865, according the report.

The median household income in the county is $45,000, according data from the U and W, and the county median household debt is $30,000 according to the UVA School of Public Health.

The average student debt in the state is $21,000 and the median student loan debt is more $18,000 for the county, according information from the state Department of Public Instruction.

The school year has seen some big changes in the last several months, including the resignation of former superintendent Michael Roeser after a tumultuous year, the closure of a large-scale public-school system and the elimination of nearly all public employee unions.

The district announced last month that it will be closing its last remaining public schools this fall and starting the new year with the hiring of some 2,000 new teachers.

It also announced it will end a contract with the state for a new school system that includes schools in the Eastern Shore, a neighborhood near downtown Baltimore.
