NOTICE: The most recent item added to this website (Sept. 1, 2026; see green checkmark in Recent Reports section) was developed
to help with TAG student selection of students using Idaho percentile ranks. Two individuals who work with TAG requested this project
in August. The SDE provided the necessary ISAT scale scores from the 2026 ISAT assessment via a public records request. I'm sure these two
"TAGers" will use the conversion tables, but my concern is that they aren't the only educators who need them and will use them. I have no way
to reach every one; I don't have the contact information. I hope "the two" will tell as many of their cohorts about this. I've also requested
that Andrea Baerwald (SDE TAG Coordinator), Anuki Nukui and Austin Ambrose (from the SDE assessment unit) help to get the word out.
