NOTICE: The most recent item added to this website [Sept. 1, 2026; see green checkmark in Recent Reports section] was
developed to assist Idaho educators with identifying TAG students using Idaho statewide percentile ranks. Two Idaho educators
who work with TAG, one from North Idaho and one from East Idaho, requested this project. The SDE provided ISAT 2026 statewide
scale score means and standard deviations for grades 3 though 8 and 11 via a public records request.
