Measuring Effectiveness
The School District Effectiveness project
measures the effectiveness of school districts in Massachusetts.
Put another way, the project measures the value that
school districts add to their students' learning experience.
The method was developed by Robert
Gaudet, a senior policy researcher at the University
of Massachusetts' Donahue Institute, a public service
think tank. Dr. Gaudet earned is doctorate in education
at the University's Amherst campus and has been a longtime
and respected education innovator and consultant. His
children attended Boston public schools for their entire
K-12 careers. He is one of the founders of the Renaissance
Charter School in Boston.
The demographic model does the following:
- Develops a profile of school districts' demography.
- Uses the demographic profile to project a likely
average test score for each school districts' public
school students. (This is done because demography
correlates strongly with test scores.)
- Compares each district's PROJECTED test score to
the ACTUAL score.
Districts that have test scores higher
than had been predicted for their demographic profile
are considered effective. The larger the gap between
projected scores and actual scores determines the level
of effectiveness. Districts that overperform their demography
may have valuable lessons to teach similar districts
about how to improve learning.
To create each demographic profile
the studies combine six conditions:
- Average income
- Education level (college or better)
- Poverty rate
- Percentage of students in private schools
- Percentage of population non-English speaking
- Percentage of single-parent households
The impact of these characteristics
on student achievement as measured on standardized tests
is evaluated using several statistical techniques including
principal component analysis and multiple regression.
The methodology is designed to promote
the following results:
- Creation of a rational measurement of the effectiveness
of public school systems in Massachusetts.
- Identification the best practices in highly effective
public school districts.
- Distribution of information on those best practices
to demographically similar school districts
