Create a Preregistration

You can create a preregistration by choosing OSF Preregistration from the list of registration forms when registering a project. You can start a preregistration from preregistration landing page. This help guide will walk you through how to start a new preregistration.

NOTE: If you plan to submit your preregistration for blinded peer-review, check to make sure that no identifying information is included in your data plan when you submit your preregistration. After submission, you can create a view-only link and anonymize your name on the "Registration Overview" page and the "Authors" section of the form; however, if your name is included in an attachment on the form, the view-only link will not work to hide this. Once you submit a preregistration, you will not be able to edit or make changes to it.

1. Start a preregistration

First, sign in to the OSF, and go to

You will be taken to the "OSF Preregistration" landing page.

This workflow creates an OSF project that connects to your preregistration. The project provides a place to continue your work and create more registrations throughout the research lifecycle.

If you have an existing OSF project that you want to preregister, click Preregister a project you already have on OSF.

Click Start a new preregistration.

A textbox will appear.

Enter a title for your preregistration into the textbox, then click Continue.

An OSF project will be created, and you will be taken to the project's "Registrations" page.

Click the New registration button.

A modal will appear with registration form types.

Select OSF Preregistration from the list, then click the Create draft button.

The preregistration form will appear.

2. Enter your research plan

There are 6 pages of questions to fill out in the preregistration form. You can save your form as a draft at any point throughout this process and continue to work on it until you are ready to register. See this help guide for instructions: Save Your Registration Form as a Draft.

Alternatively, you can download the preregistration template of the form here, fill it out locally, and then either 1) copy and paste the content into the OSF Preregistration form, or 2) attach the completed template as a file to a question in the form - if you choose this second option, simply enter "see attached file" for the questions.

Add attachments to the form

You can attach files to the preregistration form if you need more room than is available on the form itself or if you want to include supplementary material, such as analysis scripts.

If you plan to submit your preregistration for blinded peer review, make sure that you remove any identifiable information from the files before you upload them to your preregistration form. You will not be able to remove your name from these files after you register.

Only a few questions in the preregistration form allow you to add attachments.

On these questions, click the Attach File link.

A "Files" section will appear below the link.

Select OSF Storage, then either click the Upload button and select a file from a dialog box, or drag and drop a file into OSF Storage from your computer.

* If you originally clicked Preregister a project you already have on OSF, and you have files uploaded to the OSF project, then a list of files will appear below OSF Storage from which you can choose and attach to the form. Files uploaded to storage add-ons are not yet supported in this process.

The file will be attached to the question.

Remove attachments from the form

Making changes to an attachment before you register may cause the preregistration to fail. If your preregistration fails due to a modified file, don't worry! Your preregistration will be saved as a draft in your live project's "Registrations" tab that you can re-register.

If you want to make changes to an attachment - such as renaming it or editing the content - you first need to remove the attachment from the form. To remove an attachment, click the red X next to the filename. Then make the changes to the file on your computer and re-upload the file to the form.

3. Preview your preregistration

When you get to the "Other" page in your form, click the Preview for submission button.

A preview of your form will appear.

Review your answers. If you see anything you want to change, click the Continue editing button on the bottom left of the page.

4. Register

Click the Register button when you're ready.

Make your preregistration public or embargoed

The "Embargo" modal will appear.

Click inside the "Registration choice" menu. Then choose to either make your preregistration public immediately or to embargo it for up to 4 years.

If you choose to enter your preregistration into an embargo, the "Embargo End Date" box will appear below the "Registration Choice" menu.

Click inside the "Embargo End Date" box, and a calendar will appear from which you can select the date that you want to end the embargo.

Then, click the Register button to finalize your preregistration.

Your preregistration will be submitted, and will be in a "pending" state until all admins approve the registration or 48 hours pass (whichever comes first).


5. Approve or cancel your preregistration

When a project is registered, all administrators on the project are notified via email and given the chance to approve or cancel the preregistration.

The preregistration goes into effect

  • either when all administrators have approved the preregistration
  • or when 48 hours have passed (whichever comes first)

If one administrator disapproves the preregistration, the preregistration will be cancelled. You will be notified via email if an administrator disapproves the preregistration.
