It's a program you'll find only behind prison walls in Folsom -- and it's helping female inmates get jobs in architecture and engineering.Eighteen female offenders picked up certificates on Thursday after graduating from the California Prison Industry Authority's Autodesk program that trains them in computer aided design while they are incarcerated in Folsom Prison.Monica Oliva received big cheers on Thursday after graduating with certificates in AutoCAD, Inventor and Revit."I can draft plans for any type of structure -- buildings, homes and landscaping," Oliva said.Oliva has plenty to celebrate. She will be released from prison on Nov. 29, after serving 13 years for assault with a deadly weapon.“I'm getting a second chance and I'm taking advantage of it," she said.Oliva was not the only one getting another chance in life."It sounds crazy, but this is the best thing that could have happened to me," said Caitlin Churchill, a former Shasta County resident. "I have learned so much."Churchill is hoping to do design work for an architectural firm upon her release from prison in September 2016. She said she's already done 10 years for a home invasion program.Churchill is working on a design project to transform a dried out patch of prison land into a drought-resistant reception area for future graduations."We implement decomposed granite, some shredded bark, some rain gardens that actually collect their own water," she explained.Folsom's Autodesk certified training center is the only such program in the nation operating behind prison walls -- and the student inmates are motivated to learn."They want to work," said Charles Pattillo, general manager for the California Prison Industry Authority. "They want to stay out of prison. They never want to come back."The Autodesk design program costs $400,000 a year. But, Pattillo said the program ultimately saves money for taxpayers. Keeping prisoners behind bars is expensive -- about $63,000 a year per inmate, prison officials said.Autodesk is part of the California Prison Industry Authority's Career Technical Education program, which touts a recidivism rate of just 7 percent -- compared to 54 percent of inmates who return to prison overall, prison officials said."I think they have a heads up when they go to get a job because they get it," said Lynn Allen of Autodesk. "They totally get it.”Prison Industries is of course a business, but the number one product authorities insist is an offender who doesn't return to prison.The Autodesk design program at Folsom Prison started a year ago. Officials at Prison Industry Authority said one graduate has already landed a job in New York, completing some 100 projects since being released from prison 6 months ago.
