Re: runs down to the bank
In the UK, a fifth year teacher could mean:
1) A teacher of 11-year-olds, who are in their fifth year of school. (We seem to be adopting the US system of years/grades in the UK now.)
2) A teacher of 16-year-olds at a secondary school. When I went to secondary school, we joined at the age of 12 (which was confusing called "second year") and then moved up through the third, fourth and fifth years. In the fifth year, we were 16-year-olds taking our main exams. Secondary school children now start at the age of 11 and join the first year, but still move up through to the fifth year.
However, the fact that the original piece says "A fifth year teacher giving his elementary school pupils ..." shows that, in this instance, my second definition would not fit.
