NPR's David Molpus reports on how a national program for recruiting minority teachers is working in Savannah, Georgia public schools. It's called, `Pathways to Teaching,' and prepares black teacher aides, school bus drivers, custodians, and cafeteria workers to become certified classroom teachers. It pays most of their college costs, gives them some time off from their duties to attend classes, and provides them with mentors and counseling. Georgia is one of 28 states taking part in the program, funded by the DeWitt Wallace Readers Digest Foundation. The average age of the 2,000 participants nationwide is 37.
