This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q3 i? The association between FFL scores and value-added is concentrated among principals with three to six years of tenure; results are driven mainly by principals who have led their schools for at least three years. → Moira McCullough 2016

Discussion¶
Related Claims¶
- Principals with higher FFL scores make larger estimated contributions to student achievement growth (concurrent validity) — a broader claim this one bears on
- FFL scores were not associated with school leaders' estimated contributions to student achievement growth — related
- The report concludes more validity evidence is needed before using FFL scores to identify effective and ineffective school leaders — related
- Higher FFL scores associate with larger value-added for middle school principals but not for elementary or high school principals — related
- The strongest FFL validity relationships are in the systems leadership and professional and community leadership domains — related
