“For the same reason as mentioned earlier there shouldn’t be such heavy testing”
Jewish schools should have HIGHER standards, not lower standards!
“Also the secular studies teachers should be frum people that are shomrei torah umitzvot.”
The kind of model you describe will not produce shomrei torah umitzvot people who are at all competent to teach in yeshivas. You will be stuck with non-frum people and non-Jews.
