Be very careful about signing for any student loans. Make sure you understand the terms of repayment. Some schools have grants from the Michigan Jobs Commission or the Job Training Partnership Act to retrain workers. If you are not a high school graduate or if you are under 21, you will most likely be eligible for free job training. Check with your local school district adult education program.
Accreditation is an optional process.
A school can choose to go through a self-study and then request an accrediting agency to send a team of experts to visit the school. The State of Michigan does not accredit schools. The State issues a permit or license which allows the school to do business in Michigan. In Michigan, the proprietary schools issue certificates of completion. Be careful because some proprietary schools may tell you that their credits transfer.
