The Reason Foundation recently published a policy brief that offers an alternative ranking of states’ education systems. The brief, which was based on a working paper from the Department of Finance and Managerial Economics at the University of Texas at Dallas, purports to offer needed adjustments and nuance, but makes its own serious mistakes, according to a new review.
Rutgers professor Bruce D. Baker reviewed Everything You Know About State Education Rankings Is Wrong and the underlying working paper, Fixing the Currently Biased State K-12 Education Rankings. He
found the analyses provided did little or nothing to advance the
conversation about the effectiveness of state education systems.
The twin reports begin
with the presumption that high average test scores combined with lower
school spending should be the basis for state rankings, which are
reasonable premises, depending upon how the analyses are approached. But
the reports then head off the rails, Professor Baker explains.
Offering a ‘corrected’
representation of student outcomes and a crude analysis asserting that
spending has no relation to those outcomes, the reports declare states
such as New Jersey and Vermont to be poor-performing, highly inefficient
systems by comparison to many states. The reports then estimate a
regression model and assert that the higher performing states are those
with (a) weaker teachers’ unions and (b) more children in charter
schools.
However, Baker’s review
details how the reports’ so-called corrections involved unreasonable and
illogical assumptions and adjustments. For example, the reports
re-weight racial and ethnic subgroups so that they inappropriately place
equal weight in states like Vermont or Wyoming on students comprising 1
to 2% of the population as the other 98 to 99%. Other problems concern a
decision to ignore economic status entirely and a poorly executed
adjustment for cost of living.
Regressing multiple,
highly related, interdependent measures against a specious outcome
measure leads to even more suspect findings and, Baker concludes, would
only mislead policymakers.
