The bar chart compares the number of hours spent on various categories of teaching by teachers in different countries in 2001. Overall, the USA annually dominated the categories with the highest figure of hours spent on upper and lower teaching, which was closely followed by those in Ireland with similar figures in the same categories. However, teachers in Spain mainly allocated a larger number of hours to upper-class secondary teaching. It is also clear that teachers in Japan, Spain, and Ireland had similar expenditure figures on primary teaching.
In detail, teachers in the United States showed notable expenditure figures across all categories of teaching, with upper and lower classes of secondary education being emphasized. The former area of teaching stood out as the highest, followed by the largest share of time by teachers in the country, over 1000 hours, and the latter was the next-largest consumer of teachers hours per year at about 1000 hours. Teachers in Ireland, in a similar figure, shared their largest amount of time in both upper and lower secondary education, with respective figures amounting to about 7500 and 800 hours.
Teachers in Spain, in contrast, spent a higher amount of time on the upper classes. Specifically, nearly 1000 hours were spent on the upper classes, outpacing the amount of time allocated for both lower and primary categories of teaching, with both receiving 600 hours in order. Japan reflected the pattern of Japan by allocating almost similar amounts of time for almost each category of teaching. The primary part of education, conversely, was not as significant as other categories of teaching; therefore, it followed the similar number of hours by teachers in almost all countries at 600 hours. The USA, on the other hand, followed the reverse pattern, where teachers spent more time on primary education at about 700 hours.
