[quote=Anonymous][quote=Anonymous][quote=Anonymous]"I'm nevertheless still perplexed as to how a child can be 99th percentile (475Q) in math on I-Ready and be indicated as on grade level and not meeting or having incomplete knowledge of several standards."

The answer is that these are two distinct comparative metrics.  The percentile is comparing your child's performance to other children's performances.  In this metric literally all of the test takers could fail but your child could fail less badly and therefore be 99th percentile in comparison.  The grade level standard is, instead, comparing your child's performance in relation to the grade level goals (broadly defined, as discussed above).

So, the two metrics combined tell you that your child is doing fine in terms of grade level goals, and better than most other test takers, many of whom are not doing fine in relation to grade level goals [/quote]

Thanks. I do understand that. I guess my point is more that it's surprising that the standards are out of reach for so many in the nation, even kids at the 99th percentile. And DC is doing work well beyond grade level in math so it's unexpected that DC tested as being on grade level for math and not advanced in any area. The reading results make a bit more sense. Was very advanced in some areas that were expected and not so in others.

Are there data indicating that the I-Ready is accurately capturing how well students are doing relative to Common Core or Virginia Standards? I suspect the testing situation is suboptimal at best. DC said kids were sounding off "alarms" by clicking through to get to the end and that the classroom noise and particular kids make it difficult to concentrate. One disruptive kid doesn't have working headphones so everyone has to listen to his loud audio.

I also think kids could use more coaching on how to approach such tests. DC is used to being able to do things over after making a mistake (in Beast Academy, ST Math, chess, etc), which I think results in a more casual approach that backfires in a real testing situation. [/quote]

Iready is commonly thought of as a screener test for special services so it's not really meant to supplant SOLs which measure performance on grade level standards.   The assumption is that less than top 1% have needs that cannot be met by differentiation within the grade level so they are 'on grade level.'  But if you have a kid who is in the 99%ile for a few grades ahead then yes, they may need instruction outside of the differentiation offered within a class.  But it's a wide band of 'on grade level.' This is especially true 2nd grade and below where a precocious reader can get a high percentile just because they are being compared with a group that has a lot of beginning readers.  By 3rd grade, the kid may not be quite as advanced compared to their peers as reading for most kids tends to even out by then.[/quote]
