Oklahoma is a state that has an average of 6000 employed machinist and there seems to always be a need for more. The Mean Salary for Oklahoma Machinist is at $39,990 with the top 10% of machinist reaching in the low $60,000. Most of the jobs seem to be centered around either Tulsa or Oklahoma City but you can can find smaller jobs in the smaller towns of Oklahoma. With such a large market for Machinists there are several institutions that offer CNC training and even some that offer specialized certifications in harder to use CNC technology.
FTTC offers training and certifcations at several levels of CNC work. They also have a credit transfer program to local community college so you can transfer your CNC machining knowledge and get an Associates degree from the Community College after you complete the rest of the prereqs for graduations. Make sure you work with your adviser if you plan on transferring your credits in order the make the process go as smooth as possible.
MNTC is another center that offers a few levels of Certifcations. All of the classes are NIMS lvel one certified. From what I can tell they do not have a transfer program setup for you to transfer your credits over into associates degree but it may be worth calling an adviser to confirm this.
