Why identify points of
leverage?
Without focus, even the best leadership ideas will
fail, the most ideal research-based initiatives will
fail, and the most self-sacrificing earnest leaders
will fail. Worst of all, without focus by educational
leaders, students and teachers will fail.
~Doug Reeves
Outcomes: By the end of this
segment, you will have…
Identified factors that have the greatest leverage
in increasing student achievement
Considered how knowledge of greatest points of
leverage can impact our work as educational
leaders
Finding the leverage…
“There is no fixed recipe for ensuring that teaching
has the maximum possible effect on student
learning, and no set of principles that apply to all
learning for all students. But there are practices
that we know are effective and many practices that
we know are not.”
~John Hattie
Why what works doesn’t always
deliver desired results…
95-97% of what teachers do increases student
learning(Hattie, 2012), so…
The question isn’t what works, but what works
best?
What has the greatest influence on student
learning?
The typical effect
across…
900+ meta-analyses
50,000 studies, and
240+ million students

Effect Size and Percentiles
Let’s say a student scored at the 50th percentile
on a math achievement test.
The teacher decides to implement formative
assessment which, let’s say, has an effect size
of 1.0 (formative assessment has an actual
effect size of .9 (d=.90)).
With an effect size of 1.0, we would anticipate
the student would score at the 84th percentile!!
“Know thy impact”
Keep learning the focus and consider teaching in
terms of its impact on student learning.
How do you gauge your impact as the district
leader?
An exercise
Important Insights…
The most effective leaders and teachers know
their impact.
We should be aiming for an effect of 0.40.
.40 effect size as a STARTING POINT for
discussion not as the basis of DECISIONMAKING
