  • To clear up some of the misinformation going on in the website, I've been asked many questions by students and coaches.  I want to make sure to address the students who have e-mailed me:  1.  Yes, I am still the State Director of Missouri Science Olympiad, and we have added a State Tournament Coordinator who is ALSO (not former) Region 3 Director.  2.  We only put invitational information out on the new dashboard for invitationals that we are asked to publicize.  Many are true invitationals and only contacted schools can go to the tournament.  3.  We do not post any regional tournament information until the Regional Director confirms the date to the State Office, and 4.  Concerning the amount of teams that can go to nationals.  Until March/April when the national office has received all reports from the state directors and compiled their listings, no one knows who will get to take 2 teams to nationals.  We allow registrations up until 2 weeks before the regional tournament so even I don't know where are numbers are in the State of Missouri until the last regional cutoff has been done.  After that, I'm waiting, just as everyone else is, to know whether or not we will get to take 2 teams to nationals.  While I would like to know as much as you, I cannot predict the future, and I cannot speculate as I am only responsible for the State of Missouri and no other state.   Please remember that when you read things on sites and from people who are not a part of the state organization, you must take it with a grain of salt as it is highly likely it is not true.  Patty Palmietto, State Director, Missouri Science Olympiad.
