Several sources in the SchoolOS corpus speak to this mechanism. Research shapes the
questions SchoolOS asks; it does not say what will work in this school.
Leaders who stay close to what is taught, and how, shape what students experience more than those who manage teaching from a distance.
Robinson, Lloyd & Rowe (2008)
— Ensuring quality teaching · framework effect size
Effect size reported in the source leadership framework — not a prediction that improving a SchoolOS status raises achievement by the same amount.
Leaders need enough grasp of curriculum, teaching and assessment to support the work credibly.
Marzano et al. (2005)
— Knowledge of Curriculum, Instruction & Assessment · correlation
Correlation from a meta-analysis of school leadership. Correlational, not causal or additive; not a predictor for an individual school.
Staffing, supporting and monitoring teaching is core leadership work, not administration.
Leithwood et al. (2008)
— Managing the instructional programme · practice framework
Core practice described qualitatively; not an effect size.
