I like how it allows for flexibility with scheduling, so we can get everyone into school at different times during the day or week. It's also very user friendly! There are some other programs out there which seem more difficult to use than this one -- not sure why? We've been using them since they came out in 2008/2009, and have loved every minute of it! The only thing I dislike about teetertooter is having to download all the files again when our computers crash and need to be reset (happens often). Also, sometimes we don't receive the monthly emails from the system after we upload new information or schedules, but if you call customer service right away they will look up your account and ensure everything has uploaded correctly. Great program overall! Scheduling has become much easier with this system. Being able to add multiple teachers helps manage.
