Years ago there was a charter scandal website that eventually started to gather dust. In more recent years, the Network for Public Education has been collecting those various scandals under the tag #AnotherDayAnotherCharterScandal.
Now those various items are collected on the NPE website in a (partially) searchable collection. You can search by state or by category, as well as searching with terms of your own.
The searchable portion of the collection goes back through 2019; there are more items collected, but not yet indexed on the database. If you suspect there are problems with your local charter folks, or you just want to browse the size and scope of charter issues, this will be a useful tool for you.
