However, 50th to 84th is within one standard deviation (I would call this section still falling within the average range, high average, but still within average). 84th-97th is two standard deviations. Percentiles and averages have to do with relativity of scores to others.
The mid or above is about how the score compares to standards identified by the testing company. Mid to above says they are meeting the standards as laid out as being on grade level (but beyond fall expectations) or above. They're not going to say on this report that your 4th grader is meeting 5th grade standards. It's just not what it's designed to do.
The score charts take scores into higher grades. My kids score puts him into 9th and 10th grade standards as an 8th grader. The test are adaptive and introduce higher grade level material for kids answering questions correctly.
Yes, but FCPS's report isn't going to say that. Also those scores don't mean that if you plopped your 8th grader into a 9th or 10th grade class they would just fit right in and be meeting all the standards.
I can just imagine all of the calls they would receive that say put my kid a year ahead of reports provided the specifics on "or above" and how almost none of them would likely be best served by grade acceleration.
None of that to say that the information available based on the specific scores is not useful indicators for teachers and families on strengths. And weaknesses. But at the same time, I think the descriptive categories are sufficient at the upper level, given that iready should not be a independent indicator of grade acceleration. But I'm super glad that they provide the actual numeric score and not just the descriptive categories.
