The School Ranking report gives an overall ranking to schools by using
several different achievement-related measures in mathematics, English language
arts, science, and social studies.
These rankings tell us how
a school is doing relative to other schools throughout the state on student
achievement, improvement in student achievement, and student achievement gaps.
Identifying schools with high achievement gaps is a critical step toward
Michigan achieving its overriding goal of closing the achievement gap within
schools and reducing the achievement gap statewide. Additionally, identifying
schools with low achievement and/or high achievement gaps allows schools to
target their resources to areas that need the most improvement.
The statewide percentile
rank provides a number on the scale of 0-99, with 99 being the highest relative
performance statewide on tested subjects for student achievement and student
improvement. The achievement gap percentile rank provides a number on the scale
of 0-99, with 99 being the largest relative achievement gap between the top 30%
performing students and bottom 30% performing students statewide.
The School Ranking methodology
is also used to recognize Reward Schools for the high or highly improving
achievement. Reward Schools consist of schools that were identified in one of
three ways: 1) top five percent of schools on the overall School Ranking, 2)
top five percent of schools making the greatest gains in achievement
(improvement metric), or 3) "Beating the Odds."

The School Ranking report may be used to answer questions such as
How does my school compare to the rest of the state?
Look at the overall
percentile ranking. A school at the 50th percentile is doing better than 50% of
Michigan public schools.
How do my school's 3rd graders compare to the neighboring
district? To the state overall?
The school ranking
methodology ranks schools not individual students.
In what content areas do we need to improve?
For the overall statewide
percentile ranking, z-scores are provided for achievement and improvement in
each content area as these were used to determine the school’s overall
statewide percentile ranking. For the achievement gap percentile ranking,
z-scores are provided for the achievement gap in each content area as these
were used to determine the school’s achievement gap ranking. Comparing these
values with corresponding values in other content areas and other schools will
help you focus resources on closing the widest gaps, bolstering student
achievement, and increasing the rate of improvement.
The statewide school
ranking percentile is a rank on the scale of 0-99, with 99 being the highest
relative performance statewide in student achievement and student improvement
by z-scoring student scale scores in each tested subject, combining them
schoolwide, and then comparing them statewide to school on a relative basis. The
achievement gap ranking percentile is a rank on the scale of 0-99, with 99
being the highest relative achievement gap statewide between the top 30%
performing students and bottom 30% performing students. The difference between
the top 30% and bottom 30% students is determined schoolwide and then compared
to all schools statewide on a relative basis.
Schools only receive a
ranking when they have at least 30 students enrolled for a full academic year
(FAY) in at least two content areas.
Components within content
areas for the overall ranking are weighted at 50% for achievement and 50% for improvement.
The achievement gap ranking is weighted 100% on schoolwide achievement gaps in
all content areas.

Statewide Percentile Rank: schools are ranked on their
student performance in mathematics, English language arts, science and social
Improvement: student growth
percentiles (SGPs) are used for all subjects in grades 4-11 where available.
Achievement Gap: achievement gap is
calculated by subtracting the top 30% of z-scores from the bottom 30% of
Achievement Gap Ranking: schools are ranked on the
gaps between the top 30 percent of students and the bottom 30 percent of
students, based on average scale score in mathematics and English language
arts. Schools are ranked with an overall percentile from 99 to 0, with 99
indicating the highest rank (smallest gap), and 0 indicating lowest rank
Z-score: a standardized measure
that helps you compare individual student (or school) data to state average
data. A Z-score of 0 means the measure is at the state average. A Z-score of 1
means you are one standard deviation above the state average. Negative Z-scores
denote a value below the state average.
Student-level z-score: a z-score calculated
using student scores from the same test.
School-level z-score: a z-score calculated
using scores from the same content area for similar schools.
