For the news and views you might have missed
From the same people who state that any efforts made in our state to address climate change are a waste of time and that our schools don’t need any additional funding, who post reports from ALEC and have ties to the organization, comes another bit of “research” by Liz Finne, self-proclaimed expert on all things education who cranks out policy papers based on her views or others who sponsor this “public charity” organization and self-proclaimed “think tank”, the Washington Policy Center. Ms Finne, who is an attorney with no experience or degrees in education, just produced yet another opinion piece shrouded in “research based policy” on why schools in Washington State need to be privatized, her interpretation of a recently issued CREDO report.
Unfortunately our representative from the 36th District, Reuven Carlyle, has chosen this conservative think tank as one of his go-to sources of information when making decisions as Chairman of the House Finance committee in Olympia this year. We’ll have to see how that goes because the policies that come out of this “think tank” could affect the future our children will experience.
Back to the new CREDO report.
The first CREDO report on charter schools was peer-reviewed and sponsored by the Walton’s of all people. The study looked at schools in 16 states and to date covers the broadest amount of information on charter schools. The great irony about this report is it stated basically that charter schools are no better at educating our children than public schools and sometimes there was actually a reduction in “performance” by the students based on test scores.
There is a new CREDO report that was recently released stating charter school students outperform their public school counterparts in a New Jersey study.
Bruce Baker, author of School Finance 101 and a Professor in the Graduate School of Education at Rutgers, states plainly in the following graphic which is part of his post, The Secrets to Charter School Success in Newark: Comments on the NJ CREDO Report:
In his conclusion Baker writes:
So, when all is said and done, this new “charter school” report like many that have come before it leaves us sadly unfulfilled, at least with respect to its potential to provide important policy insights. Most cynically, one might argue the main finding of the report is simply that cream-skimming works – generates a solid peer effect that provides important academic advantages to a few – and serving a few is better than serving none at all (assuming the latter is really the alternative?). Keep it up! Don’t worry ’bout the rest of those kids who get shuffled off into district schools. Quite honestly, given the huge, persistent differences in student populations between high flying Newark charters and districts schools, and given the relatively consistency of research on peer group effects, it would be shocking if the CREDO report had not found that Newark charters outperform district schools.
While it is likely that there exists some strategies employed by some charters (as well as some strategies employed by some district schools) that are working quite well – THE CREDO REPORT PROVIDES ABSOLUTELY NO INSIGHTS IN THIS REGARD. It’s a classic “charter v. district” comparison – where it is assumed that “chartering” represents one set of educational/programmatic strategies and “districting” represents another – when in fact, neither is true (see the scatter of dots in my plots above to see the variations in each group!).
And this from Julia Sass, PhD, excerpts from her post:
Last week, with much fanfare, a study comparing standardized test scores of New Jersey’s charter school students to those of their public school peers was released by the Center for Research on Education Outcomes (CREDO). As a professor of public policy, a supporter of public education, and a parent of a charter school student, I have four questions that I would like to ask the authors.
Question #1: Why does the CREDO press release misrepresent the study’s findings?
The CREDO press release claimed that “New Jersey charter public schools significantly outperform their district school peers.” However, this is not even remotely what the CREDO study found.
First, the CREDO study looked at only about half of New Jersey’s charter schools (46 out of 86).
Second, the study excluded another quarter of the state’s charter school students (23 percent), particularly those from groups that score lower on standardized test scores (students who have to repeat a grade, students with special needs, and students with limited knowledge of English).
Third, the study did not include students who had left charter schools. This is especially problematic given the significant attrition levels at the highest scoring charter schools, with the most academically challenged students the most likely to leave.
So what did the CREDO study find about the performance of the remaining students?
In other words, the study looked at a limited sample of charter school students, excluding those most likely to be academically challenged, and still found that only a minority of those students outperformed their traditional public school counterparts, and only for some of the years studied.
Question #2: Why did the CREDO analysis largely ignore the dramatic demographic differences between charter and traditional public schools?
Charter schools and traditional public schools serve very different populations of students.
The CREDO study acknowledged this fact in its finding that the traditional public schools it looked at served four and a half times as many students with Limited English Proficiency and one and a half times as many special-needs students as did the charter schools…
The CREDO study did not evaluate the other dramatic demographic differences between charter and traditional public schools: income. Instead, the CREDO data treated all students from families earning up to 180 percent of the poverty line as interchangeable.
In other words, the study lumped together students who are homeless with students whose families have an income of $50,000 a year. Such differences in income are very significant when it comes to predicting academic performance. For example, a child whose family makes $40,000 a year averages 100 points higher on the SAT than a child whose family makes $20,000 a year.
CREDO tried to address these demographic differences by factoring in students’ standardized test scores at the time of charter school enrollment. However, as Professor Baker points out, this ignores the post-enrollment impact of differential poverty and disability on students’ learning…
Question #3: When will CREDO release their data so that other researchers can verify their findings?
CREDO is a part of the conservative Hoover Institution, and its charter school research is funded by the equally conservative Walton Foundation. In prior publications, CREDO has made clear that it is not a disinterested research institution. Rather, it has a policy agenda of quality “school choice” expansion.
While having an ideological agenda and funding does not preclude CREDO from producing high- quality research, it places particular importance on the transparency of their data and methods, so other researchers can replicate the results.
Unfortunately, CREDO did not release the data from the New Jersey study, although that information was provided to the individual charter schools that were included in their research.
Until CREDO provides this data to other researchers, it is not possible to evaluate fully the accuracy or validity of their findings.
My fourth and final question for the CREDO authors is: What is the objective of this research?
While the CREDO study is an improvement on similar research efforts by the New Jersey Department of Education, the study’s framing makes its findings largely useless.
If CREDO wanted to move the education policy agenda, why not look at what is causing the demographic segregation between charter and traditional public schools and how this segregation can be rectified? Or how about examining which practices at charter and traditional public schools lead to better educational outcomes that can be broadly replicated?
Unless CREDO’s goal is to feed divisive and useless debates about whether charter or traditional public schools are better, the kind of research they released last week accomplishes very little.
Seems like Ms. Finne needs to do a little more research before blowing the privatizers’ horn on charter schools yet again. For the sake of our children and their futures, hopefully Representative Carlyle will consider more carefully who he takes advice from.
