No test scores for you!

My non-proficient students took the reading proficiency test last month. I found out yesterday that the scores came in. The principal shared the overall passing rate (around 30%) with the school, but I was told that teachers will not be getting the scores or any of the score data. How am I supposed to know how each of my students did and what I need to work on in order to help them be proficient by the time the test is given again in March? So much for being effective.
