Thanks for this feedback. We were thinking of writing a paper that would explain the statistical breakdown. I think it would be very good to read for the public. |
That would be super! Or just a note on whether the changes for each school are statistically significant. I would also love to see PARCC and MSAA broken out separately, rather than rolled into a single display. I think to combine them makes the data harder to interpret. Some schools have a higher percentage of MSAA takers than others, and if combining them makes a school's performance look worse, that's basically penalizing schools that offer a lot of self-contained classrooms. I'm sure that isn't your intention! |
DP but I am not sure the data, extensive though it may be, has sufficient statistical power to draw school-level conclusions. The spreadsheet does allow for filtering to break out PARCC/MSAA data separately. |
I don't think we received the results from last year either (Hardy). But then again, that might be due to the dysfunction at Hardy, more than anything else. |
It does, but only for people who actually look at the spreadsheet. I think it's important to consider how the data is presented on MySchoolDC to less-nerdy parents. When the school system chooses to present a thumbnail summary of data, the implication is that the data is meaningful and relevant to parents. But if it's not actually statistically significant, or if it's skewed in a way that most people wouldn't be aware of, that's really unhelpful. |
And of course, I would love it if the data folks at OSSE would consider what kind of data helps parents of kids with special needs make informed decisions about school choice. I don't find the raw MSAA data very helpful at all. What can you offer, and how can you offer it, such that it might be helpful? |
The NAEP scores already show that DC is performing quite poorly (<20% proficient and ~50% at basic for Grade 8 Math). So one doesn't need PARCC to make that conclusion, although it is administered (in theory) to every DCPS student. Yes, there is a crisis and not much is being done to fix it. |
Can anyone tell me how to break out individual DCPS schools? I am sure I'm missing something obvious but I see only how to sort by LEA. |
You need to make sure you're using the school-level data spreadsheet, rather than the LEA-level spreadsheet. |
I just meant that it might be difficult to make meaningful comparisons in a granular (e.g. year-over-year for a particular grade in a given school) fashion that are statistically significant. There are too many confounding variables (demographic makeup, proportion of at-risk, ELLs etc.) that all have to be factored out over small numbers. |
Can I do a FERPA request for my kid’s score? |
I suppose, if you want to be extra. Is there a reason you need it right away? |
Won't everyone get their kids' score later this fall? |
Yes because it tells me how my kid is doing in math and whether he needs tutoring. Also the schools have this data and make placement decisions based on it, so parents ought to have access to it at the same time. This is my kids data. |
