Passionate about all things Australian. Middle school and High school ages depend entirely on individual school and when they set their Middle School. They vary from anywhere in years 6-9 (ages 10 - 15) for Middle school to Years 9-12 for High school (ages 14 - 18).
In all fairness, middle age should be about 45-70 and Senior Citizen abt 70- 100. There can be a vast difference in health and mobility of a 50 year old as compared to a 100 yr old person. Lumping everyone into Senior Classification, as seems to be the trend is short sighted and ridiculous. Anonymous Â· 2 years ago.
