TL;DR: This article reviewed the empirical literature on the relationship between the principal's role and school effectiveness during the period from 1980 to 1995 and specifically focused on the conceptual underpinnings of several theoretical models to study the role, relationship between models and methods of investigation, an4 consequently, to what has been learned about the nature of the principal impact.

TL;DR: This paper reviewed research from 1980-1995 exploring the relationship between principal leadership and student achievement and found that principals exercise a measurable, though indirect, effect on school effectiveness and student performance, while this indirect effect is relatively small, it is statistically significant and supports the general belief among educators that principals contribute to school effectiveness.

TL;DR: This book demonstrates how to use multilevel and longitudinal modeling techniques available in the IBM SPSS mixed-effects program (MIXED).

TL;DR: This book provides a broad overview of basic multilevel modeling issues and illustrates techniques building analyses around several organizational data sets, and provides an introduction to the design and analysis of research studies using two multileVEL analytic techniques--hierarchical linear modeling and structural equation modeling.

TL;DR: In this article, a model concerning how an organization's culture affects organizational performance is proposed and tested. And the authors demonstrate the application of LISREL modeling methodology to estimate and test this model.
