The Achievement LensThe Achievement Lens Provides a measure of what students
know and are able to do relative to theOhio standards, benchmarks and grade
level indicators.
Achievement tests are an important
measure of the academic learningstudents have accumulated since birth.
Creates a set of criteria for a statewide

Different starting points require differentgrowth rates. A judgment of school quality is flawed if it is
based solely on the achievement levels of itsstudents.
Problematic diagnostic value
What part of academic achievement is due to SESand what part is due to the school?
Achievement Targets tend to motivatestudents and teachers who are within reach
of those targets.

1. We collect all of the individual student data
that is available for students.2. All of these data points are used to develop
individual student academic profiles.

3. Each students profile is added to a pool that containsthe profiles of all students, present and past, who have
taken the same year-end assessments.

The actual results of other students
who have profiles very similar to
Student One are used to create a
statistical projection of where
Student One is likely to be at theend of a given academic year.
4. The profiles of other students with similar performance
histories are then used to create statistically reliable
projected scores for each student .

Research NuggetsResearch NuggetsTeachers matter The difference between having a high and a low
quality teacher 3 years in a row is roughly 50
percentile points. Differences within schools are typically greater
than differences across schools.
Only the most effective teachers - the top 20per cent are providing instruction thatproduces adequate gain in high-achievingstudents, while students in the lowerachievement levels profit from all but the least
effective teachers.

Both are important
to parents,
teachers, and
community
Is the ultimate metric for
student post-secondary
opportunities
Compares year to year
performances of unlike cohorts on
School Report Card
Is significantly related to student
family background
Simply put, achievement status
conveys the degree to which a
student or cohort demonstrates
performance mastery
Much of the foundational research
using this form reported
discouraging school influence onstudent achievement
Measures the progress
students make between
two points in time
Is largely unrelated to student
background factors
Though the calculations require
involved data structures, capacity, and
statistical technology, the concept is
straightforward student progress
The more recent research using this
metric found the schools / teachers
influence to be paramount forfacilitating student academic
progress
A usable gauge for measuring
school program effectiveness
for anyway that students are
grouped
