If there's anything to know about schools here in the North our Jo knows it all!! She is the expert!! :-)
As for my opinion on Golden Grove Primary, heard nothing but bad things recently and there has been an surge of people from there trying to get into Greenwith Primary, which I highly recommend and is a great school!!
The Heights again is another that keep hearing bad things about recently but as is always said each to their own!! My advice look at as many as you can and go with the gut instinct, so many different views on here on such an important matter you are the one that needs to go see if the school suits your kids! Good Luck!
