When you are preparing to introduce your young students or child to that amazing website for kids that you found there is something to check for. Look for something on the page that indicates that the site is COPPA compliant. COPPA ( Children's Online Privacy Protection Act) was established in 1998 to protect children under the age of 13 while online. It requires sites that market to the under 13 population to get parental permission to collect data and the site is required to protect that data from being used or seen by others.
BEWARE - there are many sites that make the product attractive to children under thirteen but the terms and agreements will indicate that you must be over thirteen to use the product.
