Special Competition for Young Investigators: In an effort to enable younger scholars to field larger-scale studies than what TESS normally conducts, we are pleased to announce a Special Competition for Young Investigators. This Special Competition is limited to graduate students and individuals who are who are no more than 3 years post-PhD (after 1/1/14). Winning projects will be allowed to be fielded at a size up to twice the usual budget as a regular TESS study.

We will begin accepting proposals for the Special Competition on August 1, 2017, and the deadline is October 1, 2017. Full details about the competition are available here. This page includes information about what is required of proposals and how to submit, and should be reviewed by anyone entering the competition.

NSF Funding Renewed: We are pleased to announce that Time-Sharing Experiments for the Social Sciences (TESS) was renewed for another round of funding by National Science Foundation. TESS allows researchers to submit proposals for experiments to be conducted on a nationally-representative, probability-based Internet platform, and successful proposals are fielded at no cost to investigators. The studies will be fielded by NORC at the University of Chicago, using their AmeriSpeak® Panel.

Additionally, we are pleased to announce the continuation of TESS’s Short Studies Program (SSP). This program accepts proposals for fielding very brief population-based survey experiments on a general population of at least 2000 adults. SSP recruits participants from within the U.S. using the same Internet-based platform as other TESS studies. More information about SSP and proposal requirements is available here. We are being assisted by a team of over 60 Associate PIs and peer reviewers across the social sciences. More information about our APIs is available here.

Winners of Special Competition for Young Investigators: TESS is pleased to announce the winning proposals of our competition for young investigators. The 6 winning proposals and authors are listed here. Congratulations to the winners and thank you to all who submitted proposals! (6/2016)

Policy change: TESS will begin posting accepted proposals for fielded projects online when it posts the raw data. Click here for details. (7/2014)

Time-sharing Experiments for the Social Sciences (TESS) offers researchers the opportunity to capture the internal validity of experiments while also realizing the benefits of working with a large, diverse population of research participants.

Investigators submit proposals for experiments, and TESS fields successful proposals for free on a representative sample of adults in the United States using NORC's AmeriSpeak® Panel, a probability-based and highly-respected representative survey platform.

The current principal investigators of TESS are Jeremy Freese (Stanford University) and James Druckman (Northwestern University). TESS was started by Arthur Lupia (University of Michigan) and Diana Mutz (University of Pennsylvania).

TESS is funded by the National Science Foundation (SES-1628057).
