MARIETTA — Chattahoochee Technical College is cutting 25 jobs, the school announced Tuesday.

The technical school, which has eight campuses in six counties, is laying off 12 part-time and six full-time employees, spokeswoman Rebecca Long said. She said the cuts will come across its system, which includes the main campus on South Cobb Drive in Marietta, as well as locations in Austell, northeast Cobb and Acworth.

“This does not include such positions as adjunct instructors, who are hired on a per-term basis depending on enrollment, class size and program needs,” Long said.

In addition, seven vacant full-time positions will not be filled, she said.

Long said the majority of the jobs being cut are staff positions with administrative responsibilities, but four come from academic programs that may be eliminated.

“This means that the program is being evaluated based on industry needs, enrollment and other factors to determine its place at CTC,” she said. “Changing needs of local industry and even changing technology are both contributing factors.”

Programs coming under review in the past year include diesel equipment technology, early childhood care and education, electronics technology, physical therapist assistant, industrial systems technology, electrical systems, automotive, medical assisting and practical nursing. Long said the review can lead to changes in a program’s curriculum, admission requirements or focus.

Other positions being eliminated include some evening administrators, whose duties can now be performed by public safety officers, Long said.

“With the growth of our public safety department, the positions became redundant,” she said.

Some employees being let go will continue in other positions at Chattahoochee Tech, including as part-time adjunct professors, Long said.

Long said Chattahoochee Tech hasn’t laid off any employees in at least 20 years.

The cuts come as Chattahoochee Tech finalizes its budget for the next fiscal year, which starts July 1. While she said the numbers haven’t been finalized, Long expects the fiscal year 2013 budget to be “in the same ballpark” as the $58 million budget for the current fiscal year.

Some of the laid-off employees may be moved into adjunct instructor positions, Long said.

The school had 11,200 students enrolled in at least one class during the spring 2012 semester. Long said that number includes those who took traditional, hybrid and online classes, or a combination of the three.
