Teacher salary study

U.S. teacher salaries among lowest in developed nations
Compared to the country's economy, U.S. teacher salaries are near the bottom of 30 developed countries even though primary-level teachers log on average of 1,080 hours annually compared to an average 803 in other countries, according to an international education survey. The U.S. average $40,000 annual pay for an elementary teacher with 15 years experience ranks 12th internationally, but among the lowest when compared to the U.S. gross domestic product; the same teacher would earn $88,000 in Luxembourg.
