"102 CORRECTION"

RE: Idaho's ISAT "percentile results" - 2015 to 2017 [Revised Jan. 17, 2018]


CORRECTION.  This paper was revised on Jan. 17, 2018.  I had mistakenly transferred Table 1 values for the 10th, 25th, 50th, 75th, and 90th percentiles to Table 2 in reverse order to the 90th, 75th, 50th, 25th and 10th percentiles.  It followed that Figure 2 and related narratives were not only incorrect, but exactly wrong.  I have corrected Table 2 and Figure 2 (with narratives).  If your copy has no date (a draft) or an earlier date in the upper right-hand corner of each page, please destroy it. Then download a revised copy (Jan. 17, 2018, appears in the upper right-hand corner) at PDF

My apologies for the confusion. I have learned a lesson; I will never make this mistake again.


Understanding ISAT by SBAC

  2. What Percent Proficient or Advanced means in the new ISAT (15-010)
  3. Idaho's SBAC "Grade 10" graduation requirement is unreasonable ( 16-002)
  4. Scale scores are needed to understand ISAT results (16-003)  [Achievement levels are inadequate.]
