The bar charts illustrate the duration of time that teachers in four countries spent teaching across three different educational levels in 2001. Overall, a teacher in the USA spends the most hours at three school levels among those countries, while the figure for Japan was the lowest. It is clear that teachers in all countries spend time at lower secondary and upper secondary more than the primary school.
In Japan, 600 hours spent at primary school by a teacher, is a little bit higher than the figure for Iceland, at approximately 600 hours. In the United States, primary school teachers worked over 750 hours, which is 100 hours higher than the figure for Spain.
In all four countries, the number of hours worked by lower secondary and upper secondary school teachers was higher than that of primary school teachers, with American teachers working the most extended hours of 1,000 and 1,200, respectively. In Spain and Iceland, upper secondary teachers worked 900 hours, 150 and 200 hours more than middle school teachers in Spain and high school teachers in Japan, respectively.
