Think Twice Review Date:	December 14, 2006
Reviewer:	Jeff MacSwan, Arizona State University
In this review, MacSwan indicates that the report is riddled with flaws. He points out that neither the data presented nor could the author's analysis of that data support the conclusions drawn in the report. MacSwan indicates that the report suffers from poorly sampled data, inaccurate descriptions of district-level policies, failure to account for alternative explanations of observed changes in district testing data, and lack of any serious analysis of the data presented.

 

Report Reviewed:	Giving Students the Chaff: How to Find and Keep the Teachers We Need
Think Tank:	Cato Foundation
This report asserts that school choice, in the form of private-school vouchers and charter schools, will improve the quality of teachers.
Think Twice Review Date:	October 25, 2006
Reviewer:	Raymond Pecheone & Ash Vasudeva, Stanford University
This review concludes that the CATO report's initial premise that teacher quality plays a large role in improving educational outcomes is well founded in educational research. However, the report's subsequent conclusion that competition and choice lead to improved hiring practices which will attract and retain high quality teachers lacks evidentiary support and ignores other important evidence.

 

Report Reviewed:	Getting Farther Ahead by Staying Behind: A Second-Year Evaluation of Florida's Policy to End Social Promotion (2006)
Think Tanks:	Manhattan Institute
This report concludes that Florida's policy of retaining third-grade students based on their scores on a standardized reading test has helped them to improve their reading.
Think Twice Review Date:	October 10, 2006
Reviewer:	Derek Briggs, University of Colorado at Boulder
In this review, Briggs points out that though the findings in the report are suggestive and merit further investigation, it contains some principal shortcomings which undermine the validity of the conclusions drawn. Among the shortcomings is the fact that the authors are unable to isolate the effect of repeating the same grade from the effects of attending summer school and receiving intensive reading instruction which are mandatory parts of Florida's retention policy.

 

Report Reviewed:	Segregation Levels in Cleveland Public Schools and the Cleveland Voucher Program
Think Tanks:	The Friedman Foundation and the Buckeye Institute
This report finds that private schools participating in the Cleveland voucher program are less segregated than the city's public schools.
Think Twice Review Date:	October 5, 2006
Reviewer:	Gary Ritter, University of Arkansas
Ritter's review indicates that though the methodology and analysis in the report appear sound, the conclusions drawn by its authors should have been more cautious and that some "overreach" the data presented. He cautions that with regard to the effect of school choice plans on segregation, the Cleveland and national data in the report offer only a small piece of a very large puzzle.

 

Report Reviewed:	The State of State Standards 2006
Think Tank:	Fordham Institute
The report assigns grades to the academic content standards in each state and claims that higher content standards lead to better student test scores.
Think Twice Review Date:	September 11, 2006
Reviewer:	Kenneth Howe, University of Colorado
In his review of the report, Howe finds no evidence to support the validity of the grades and also found no support for the report’s claim that higher content standards lead to an increase in student achievement.

 

Report Reviewed:	On the Public-Private School Achievement Debate
Think Tank:	Program for Education Policy and Governance
This report claims that private schools outperform public schools.
Think Twice Review Date:	August 30, 2006
Reviewer:	Christopher Lubienski and Sarah Theule Lubienski, University of Illinois
The Lubienskis’ review of the report finds that the evidence and claims made in the report are critically flawed. Among other things, the researchers did not control for key student demographic data and student-reported data neglected to include key information.

 

Report Reviewed:	The Financial Impact of Ohio’s Charter Schools
Think Tank:	The Buckeye Institute for Public Policy Solutions
This report claims that charter schools in the “Big Eight” urban school districts in Ohio are producing greater student achievement gains, increasing revenues for traditional public schools, and operating at lower costs.
Think Twice Review Date:	August 1, 2006
Reviewer:	Gene V Glass, Arizona State University
Glass’s review of the report reveals that its claims are without merit and should not be used to guide public policy. Among other things, the review reveals a lack of scholarly research to support the claim of increased student achievement in charters.
