For a more detailed, yet still accessible, overview of the law, you can also check out EdWeek's "COPPA and Schools: The (Other) Federal Student Privacy Law, Explained." The article gets into the somewhat confusing and contentious issue of whether or not schools can stand in for kids' parents when giving consent. In short, schools can grant COPPA consent if -- here's the tricky part -- the tool is used solely for an educational purpose. As the FTC explains in its COPPA FAQs, the information collected must be "for the use and benefit of the school, and for no other commercial purpose." And it can often be hard to tell exactly where that line is drawn. In addition to knowing when teachers and schools can consent on behalf of parents, teachers and schools should also follow other best practices with respect to COPPA: conducting appropriate due diligence in vetting products, and providing appropriate information to parents (such as the names of sites or services it has consented to on behalf of parents, and those sites and services' information practices). Beyond COPPA's parental consent issue, it's important to know that even though the law specifically regulates technology companies, teachers and schools aren't off the hook when it comes to understanding the law and its intent. can you summerize and describe what COPPA is in my own words
