"Effective education leadership makes a
difference in improving learning.
There’s nothing new or especially
controversial about that idea. What’s
far less clear, even after several decades
of school renewal efforts, is just how
leadership matters, how important those
effects are in promoting the learning of
all children, and what the essential
ingredients of successful leadership are.
Lacking solid evidence to answer these
questions, those who have sought to
make the case for greater attention and
investment in leadership as a pathway
for large-scale education improvement
have had to rely more on faith than fact."
