Working Paper Series

In 2011, Mathematica launched a working paper series to offer timely access to its most current research and in-depth analyses behind our traditional publications. The series makes results available in preliminary form to encourage discussion and suggestions for revision before final peer review and publication. In keeping with Mathematica’s high standards of quality, working papers undergo a rigorous internal quality review.

"Is There a Trade-off Between Quality and Cost? Telephone Versus Face-to-Face Interviewing of Persons with Disabilities" (February 2012)
"Assessing the Rothstein Test: Does It Really Show Teacher Value-Added Models Are Biased?" (February 2012)
