有错误.
1,把that改为when
2,把句尾的in去掉
这是个表时间的从句,the school was set up 是修饰时间1970,表示在这个时间所发生的事件,that不可以引导事件状语从句；句尾的in,本来是in 1970,但是1970前提,作为了从句的主语,这个in要去掉,也可以这样理解,把in"融"在了when中.

平常都是it was in 1970 when the school was set up.
你呢个似乎语法上没错，不过没什么人这样说诶

有！应该是in 1970

有
in不能放在句末，而应该加在1970前面
It was in 1970 that the school was set up.
这是一句强调句
