Many public high schools in Tennessee offer CNA classes for their students. However, if you are not attending a high school offering these classes, there are technically no free classes offered in Nashville. If you become employed at a local nursing home, many of these facilities will reimburse employees for the cost of attending class. One nursing home that offers tuition reimbursement is Nashville Metro Bordeaux Hosp ? 1414 County Hospital Rd Nashville, Tennessee 37218.
