I still can't really grasp why they do that.
Best I can remember it was because someone (?) in the county school system saw where another system did this. It was thought that the 9th grade in a location by itself would make the students better adjusted when then entered the 10th grade.
I question if that makes much sense or not. When I was at Grove we had Jr. High, 7-8&9 and then we went up to what we called the "hill" for the 10-11&12... I don't remember there being much of a change from the 9th to the 10th.
But, now that the county school system just spent $5 million on a new building it's not likely to change anytime soon.
Also, as someone said, if the 9th grade was moved to the current high school there would be no room... true.
Before this new building was built I had suggested we move the 9th grade back to the high school, but first it would require a new high school. But, as you can see that didn't happen.
I don't see much difference in going from the 8th grade to the 9th than it would be going from the 9th to the 10th... that's why I suggested putting the 9th grade back in the high school and then build a secon high school. But, what do I know!!!
This is always a possibility, but it will be another 10 years before that happens unless Henry County suddenly has a population/growing boom and the current high school become seriously overcrowded.
