How can I find out information about a public school?

We are hoping to buy a new home, but want to consider the potential public high school. My children currently attend a small private school that they and we love and that is affordable. However, this school only goes until grade 8. I’ve looked at some private high schools, but the costs are significantly higher. We are not sure we could afford them without making drastic changes (which we would rather not).

I’ve done a little digging, but unfortunately, the internet almost gives waaay too much information and sometimes conflicting information. I honestly would not know which website to trust " some give parents comments and ratings, but with only a couple of individuals responding, could they just be disgruntle or even the opposite some teacher writing pretending to be a parent.

So what and where should I look for this information? There was one neighborhood in a town we were considering, but I read that last year that had a potential not be accredited, but this did not happen. Not sure why " it had something to do with funding (what doesn’t) " but the high school on the surface has a very low teacher/student ratio and a high graduation rate with activities that fall into my kids’ interest. Should this be a red flag?
