Tools/sites for evaluating school districts?

[Alex Mayberry]

Hey, I'm wondering if anyone can help me out. 

I am looking to buy a turnkey rental out of state, and want to check out the school districts that some of these properties are in to filter some out. At first glance, I found schooldigger as a source that seems alright, since they at least use multiple statistics to come to a rating. 

Do any of you have a good site or source that you trust for "vetting" the schools/school districts? Anything would be appreciated.
