Raw scores are rarely released for many invitationals. At most you know your own score from the test packets they usually give you at the end of the day.
Actually, it's both. Most invites *in the country* don't release anything related to scores. It's more a Michigan invite thing (not sure about every one, but I'll assume you know better than me), along with maybe a few other states (as Unome indicated) and one or two university invites off the top of my head.
Releasing histograms wasn't my decision, but I don't feel the need to protest it. Score distributions are often informative and focus on what matters. Among other things, they indicate how you do relatively, give a measure of how bad, hard, etc a test was, and tell you the max if you care (like with builds). Overall, they tell just as much as raw scores and help you to focus on relative results (which is what matters really).
I am unsure of any issues with this, unless you think distributions or histograms were done incorrectly. If something sounds wrong with this, please say. Otherwise, hope to update soon!
But this is Michigan and that is the standard in Michigan. Just keep in mind if teams feel like they are not getting the full benefit of coming to the tournament, they may not return. I don't understand the secrecy, that is one of the big takeaways we get from invitationals.
We might have to agree to disagree on this one. As a student who competed in MI for six years, I totally understand that most tournaments here release their raw scores to teams. Several members of our board raised valid concerns to releasing them, and releasing the histograms was a compromise that we all liked. We 100% feel that you will attain all of the same information from the histograms that you would from the pure raw scores. In fact, in some cases, you may get more information. For example, raw scores in Hovercraft don't tell you much, since they are curved. Four of the histograms are in the test folder already (Mat sci, Chem lab, Fermi, and Hovercraft) with more to come when I finish studying tonight or tomorrow. With Chem Lab and Fermi, the distribution is also done question-by-question, so teams know how hard each individual question was (thanks kenniky!). Unfortunately, I did not collect such data on Hovercraft and Mat Sci, and obviously, we do not have the tests anymore!
If you have concerns, or specific requests for information to be placed on the histogram, please feel free to message me, although I cannot guarantee I'll respond tonight. Midterms... *sigh*.
Also, kenniky is correct saying that the raw scores release violates FERPA, and we did not collect waivers from students on that. Among other things, that was one of the concerns of our board. As we are a University group, we have to be very careful to comply with University policies (as you know from all of the paperwork you had to bring for your students!).
