I'm just curious. Ds had the state-wide reading and math evaluatins earlier this month and I will need to follow up with teachers etc about his results. Can I assume that they will be familiar with his scores?
No.
Schools do look at results, but usually in aggregate, when making instructional groupings, or when screening for at-risk students. No reason to expect them to know your specific child's scores.
DD's teachers said they used the scores from the state testing last spring (along with other testing data they had) to ability-group the kids for math/reading. So it happens but I doubt every teacher/school does this. The teachers seem to use the computerized testing done for the district more often...at least to identify the low-performing kids because those kids are eligible for special pull-out services, and figure out which kids are high-ability so they can proceed to ignore them.
This testing is done 2-3 times per year and is not required by the State.
I don't know how your state operates, but the scores weren't even available or released for 5 months. I still don't have any specifics, although I see some numbers posted online in DD's records now.
Ditto what aeh said, plus one additional caveat, which will be dependent on your state. Our state's standardized testing is designed only to check to see if students have mastered the bare bones of the curriculum goals for the grade they are in, and it's also a relatively low number of questions of each type. Hence it is not a test that will separate out kids who are truly working ahead - for instance, in the schools my kids have been in (in elementary, and not gifted magnet schools), it wasn't unusual for 25% or more of the students to score in the "advanced" category, so in our state, it's really not a test that can be used if you're advocating for differentiated work for your child. It's more often used to flag children who need extra help because they aren't keeping pace with the curriculum.
This could be entirely different where you live - I'd try to read everything you can on the test, and also see if you can view test summaries by school online to get an idea of how many students score in each category.
