Reading the evidence codes

q is the design tier, i the impact, n the sample, and the kind with its r the rigour judged within that kind: what each code means.

This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.

q1 i? The report analyzes how many teachers met IMPACT dismissal criteria and were dismissed, compares overall retention before IMPACT (2008–2009) to the first three IMPACT years, and compares retention of the most effective teachers and of teachers at individual schools over time. → Elias Walsh 2014

q1 · i? · associational · r?

The report's first research question, as stated on the publication page, frames a longitudinal analysis of DCPS teacher retention under IMPACT, examining dismissals, overall retention from 2008–2009 onward, and retention of the most effective teachers. The page states the report will "compare the overall retention rate for teachers in the 2008–2009 school year" to later years. No findings are printed on this page.

"Have retention rates of effective teachers changed since the first year of IMPACT? Because teachers who earn an ineffective rating in one year or a minimally effective rating for two consecutive years are dismissed under IMPACT, overall retention rates may fall even as effective teachers are retained at higher rates."
