The Preregistration Challenge was an education campaign that ended on December 31, 2018 and was supported by the Laura and John Arnold Foundation. The campaign included $1000 prizes for researchers who published the results of preregistered work. This page contains information about that campaign and will not be updated. For a list of prize winners, please see this announcement. For more about preregistration, please see

The Preregistration Challenge

Preregistration is an unfamiliar practice in many areas of science. We will give 1,000 awards of $1,000 each to promote education and experience with preregistration. Award winners will have completed a preregistration using OSF and published the results in an eligible journal. All it takes is a single experiment and its analysis to be eligible. 

How to Earn the Prize

  1. Plan your study and analyses.

    Design your study and how you will analyze the data. The Preregistration workflow on OSF will guide you through study design and analysis planning. You can save your progress and return later to continue. You may also use this Google doc template or this Word template and move the content to OSF  later. See this guide on using OSF

  2. Submit your plan on OSF.

    Once you and your collaborators complete the design and analysis plan, submit it for review to assess eligibility for the prize. We will review your plan to check for completeness and adherence to the eligibility criteria This is not peer review of your research. Once accepted, your research plan will be registered and eligible for the prize. Preregistrations must be pre-approved to be eligible.

  3. Do your science.

    This part is all up to you!

  4. Analyze and write according to your preregistered plan.

    Report the results of all preregistered analyses. Any  additional exploratory analysis is encouraged, but must be clearly differentiated from the confirmatory analyses in your report. Include a URL link to your preregistered project on OSF. 

  5. Submit your manuscript for publication.

    Submit your manuscript to an eligible journal (view the "Eligible Journals" tab on the left). 

  6. Submit your published article to confirm completion of the Preregistration Challenge.

    As soon as your article is published online, email to confirm that the final article meets all eligibility requirements. If it does, the article is eligible for the next prize award date.

  7. Receive your $1000 prize!

    The 1,000 prizes will be awarded across 4 award dates. If more eligible articles are submitted than available awards during that award period, then the eligible articles will be ranked by Preregistration date with earlier registrations being awarded first. Non-awarded entries will remain in the eligible pool for the next award date:

    • July 1, 2017: up to 100 Prizes
    • January 1, 2018: up to 100 Prizes
    • July 1, 2018: up to 250 Prizes
    • December 31, 2018: All remaining Prizes

Eligibility Criteria

There is a detailed description of the terms and conditions for the Preregistration Challenge to meet legal requirements and maximize the fair administration of the process. Here are highlights of key items:

  1. Articles must be published in an eligible journal.
  2. Before becoming a preregistration, submissions to the Challenge must be reviewed for adherence to the eligibility criteria. Once accepted, submissions become a static, time stamped preregistration. Please do not begin your study until it is registered. Submissions are generally reviewed within the same business day.
  3. The published article must also be reviewed and approved for meeting eligibility criteria.
  4. U.S. law restricts eligibility of contests like this one from being administered within the U.S. State Department's list of embargoed countries. Therefore, residents of those countries may not participate in the Preregistration Challenge.
  5. The use of pre-existing data may make your registration ineligible for the Preregistration Challenge. See the FAQ tab for more info.
  6. When awarded, one prize is given per published article to the article author that submitted the preregistration that was approved by the Challenge administrators.
  7. Awardees can earn only one prize each, but can enter as many times as they wish and can be co-authors on other awarded entries.
  8. Prizes will be awarded at pre-determined dates to eligible entrants. If more eligible entrants exist than available prizes, entrants will be ranked based on the date of registration.
  9. Entering the Preregistration Challenge requires that you agree to all of its terms. If you do not agree to the terms you may still continue, use the form, and register your research study without entering the Challenge.

As experience is gained with preregistration and the Challenge process, we expect that we will identify ways to improve the process and requirements. We will make updates as is needed and document those changes. Prior entrants will not lose eligibility based on future changes. The eligibility criteria and preregistration process is currently version 1.0.0. Check the change log here.
