I completely agree. You need to take this one to the next level. It does not sound like a new teacher will solve this, since it is the principal.
Even though you are not upset that parents are not automatically given the scores, frankly, I am. There are many parents who would just not know enough to ask, but are entitled to the information since every other parent in the district gets them.
I would play dumb with the district. I would not sound accusatory, but I would ask if there is a district policy in HOW the results are shared with students. Make this your starting point.
And this is coming from someone who does not even "like" standardized tests!
That's a whole other issue, then, and it sounds like it's one that should be addressed at the district level. It doesn't make sense for score reports to go out to some schools and not to yours. While I could see there being some bugs to work out of the communication chain as a school implements a testing program, it's totally wrong for the principal to refuse to release scores. And it doesn't make any sense for the school from a PR perspective--most schools are falling over themselves to show what they are doing to improve students' test scores, it seems. Especially since it sounds like your school is pushing for data-driven instruction (which is a good thing, and what MAP promotes), it seems really odd that the administration at your school hasn't figured out how to share that information.
