Just got my DD CAASPP report in California. I am trying to find percentile information for the scores. Does anyone know where I can find these?
Thanks aeh. Do you know if info for last year world be there somewhere? Cannot imagine it changes very much.
I believe last year was a benchmarking year, so the data in CA were probably not as complete (and likely capped at the high end). This is the SBAC benchmarking document:
http://www.smarterbalanced.org/assessments/scores/You might be able to get an approximation of percentiles by using the X & SDs in the first table of this document, taken from the field test data. (Calculate the number of SDs +/- the mean, and then look up the corresponding percentile in any table of normal distributions.):

I just found this.
http://www.smarterbalanced.org/assessments/development/percentiles/Unfortunately it doesn't go above the 95th percentile.
My school district has published the mean scale scores for their SBAC results. If I want to find my daughter's percentile score, can I still use the standard deviations published on Smarter Balanced website even though they have different mean scale scores? In other words, does a change in the mean scale score change the standard deviation?
If you want to find her local percentile, then no, you cannot use the national standard deviations. If you want to find her national percentile, then yes, you may use the national standard deviations. Did the district not publish local standard deviations, to go with their local means?
Statistically speaking the mean/SD apply to the entire state sample. If you school has a different mean then the SD is also likely to be different. But you can go to the CAASPP site and it shows for your school how much are above average etc. This might help you get an idea on where you stand. But do not it is very coarse. It shows 50% of kids in our school exceed expectations. Makes we wonder if the standards are too low.

Not on the report I'm looking at at least.
That would give me a very broad generalization, but since this is really not more than a curiosity, I guess I'm not going to worry about it too much.
My son got >95th percentile on both parts for 7th grade! I'm just glad that he didn't flunk it as the Common Core testing is kind of whacky. He's in 8th grade now in the 9th grade Integrated Math 2 class, which so far is all review for him.
Our school published the scores as well. But they also published a SD. So if you are interested you can ask your principal
