According to a new U.T. study, Tennessee is not producing enough teachers to meet demand created by expanded math and science classes and lower student-to-teacher ratios.

The U.T. Center for Business and Economic Research estimates a shortage of more than 11,000 teachers for the 2010-2011 school year. The shortage is expected to grow to over 31,000 cumulatively (about 40% of total teachers) by 2013-2014.

The state will have to recruit teachers from out of state, and in some cases teachers will likely be teaching technical subjects for which they aren't trained, according to the report.

The highest demand in 2010-2011 will be for teachers certified to teach English as a Second Language (ESL); elementary school music, art and physical education; eighth grade; and vocational education.
