For math it can be a bit goofy because it doesn't ask that many questions so your kid will score low if it asks weird things they haven't covered or don't recall, even if the kid is solid on the topic generally.

For instance, your kid may be asked to convert gallons to liters. They may know how to do this math, but not know that conversation factor, so they get the problem wrong.

No. If you watch students use it, it’s fairly easy to tell it’s not really a measure of understanding. I suppose one might say something about speed and accuracy as data points, but I’m beginning to wonder if using these kinds of programs isn’t training students to guess what the question is asking quickly for a dopamine hit.

Our results skew high. For example our 6th grader is in the 1200-1300 scores for reading but still is only in the 96ish percentile on Map.

Interestingly, I have heard a bunch of people say their kids score unexpectedly low in measurement in IXL.

IDK if that’s true but our results and anyone I’ve talked to have been a hot mess. I don’t know that I would really trust it for anything. For us it definitely reflected lower achievement than I can see by other measures. And when you get to the point that a fourth grader is reported not to know the difference between short and tall? Come on.

H is telling me they also have a data selling scandal?

It says my fourth grader doesn’t know the difference between short and tall. This is definitely false. Most of the metrics were wrong.

It says he is at 5th grade level in algebraic skills. This is true. It feels like a broken clock kind of right though. It definitely seems like a flawed assessment.
