The Education Leadership Judgement Indicator (E-LJI)

The video introduces the currently unpublished Education Leadership Judgement Indicator (E-LJI). Hogrefe holds the publishing rights, but this earlier video explains how the authors developed the E-LJI to assess a school leader’s judgement and preferred leadership styles when responding to a range of school management decision-making situations.

The E-LJI was written by Tamba Roy, in collaboration with Michael Lock and Bob Wheeler, co-authors of the wider LJI suite now published by Hogrefe. Tamba’s perspective on school leadership was shaped by two highly successful headships, including Ofsted recognition for “outstanding leadership”.

A useful technical point is that its internal consistency has been estimated using the paired-item (unit of judgement) approach, which matches how the LJI instruments actually work (they are built from repeated judgement comparisons, not from a single homogeneous “scenario” scale). Using a dataset of N = 168, the statistician John Cox calculated reliability and reported a paired-item Cronbach’s alpha of 0.87. The implication is straightforward: across the set of judgement comparisons, respondents are showing a highly coherent and stable pattern of leadership judgement, giving users confidence that the overall judgement signal is consistent enough to support meaningful feedback, development discussion, and (where appropriate) assessment use if it were eventually to be published.
