Subclaims¶
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.
q2 i? If the Career Ladder has a positive effect on test scores, it is likely to be very small, with estimated effects ranging from small positive effects to no effect. → Kevin Booker 2008
q2 i? Estimated effects of the Missouri Career Ladder program on district math and reading achievement range from small positive effects to no effect in both subjects. → Kevin Booker 2009

Quasi-experimental matched comparison of 524 Missouri school districts over a nine-year period, using longitudinal data on district math and reading scores; "estimated effects range from small positive effects to no effect."
"The paper compares achievement levels in participating districts with those of a matched group of nonparticipating districts. The estimated effects range from small positive effects to no effect."

- School district participation in the Missouri Career Ladder Program tends to increase teacher retention in the district and the profession, especially for mid-career teachers — related
- The program's achievement effects were estimated statewide using nine years of longitudinal math and reading scores from 524 Missouri school districts — related
