During a BOCES Common Core Math Camp this week an interesting discussion came up that I wanted to post on the list serve to draw attention and gain input about. We were discussing the June 3rd Common Core assessment timeline and how NYSED plans to Post-Equate the scores for the new Algebra Common Core assessment in order to avoid a Math A repeat. Our discussion was in concern about skewed results based on the population.
Most schools offer a 2 year stretch Algebra course. Students that took year 1 of that course with the 2005 standards last year will continue with the 2005 standards taking year 2 this year culminating in the old regents exam in June. Students just entering 9th grade taking the 2 year stretch course will not be taking a regents exam in june and instead will wait until 2015 to take the Common Core Regents Exam in Algebra 1. What this means is that in the 2014 administration of the exam, the lowest students will not be taking the Common Core exam. Our concern is if NYS post equates the exams based on the 2014 results and then uses that formula, curve (what ever you want to call it) to convert any subsequent years results it will be skewed data because the lowest of the students weren't factored in.
We know they must have (I hope) considered this when they would have had the same issue when phasing into new curriculums in the past but we were wondering if anyone has heard anything from NYS about this issue and wanted to make sure they were aware of it.
