Supplemental Forms

Collecting additional applicant information is often essential—whether that means gathering third-party references, collecting nomination data, or enabling ongoing reporting after applicants are selected. Reviewr’s Supplemental Forms feature centralizes all of these downstream deliverables into a seamless, trackable, and automated workflow. Instead of relying on uploads, email chains, or disconnected tools, Supplemental Forms allow programs to collect structured, purpose-built forms that attach directly to an applicant’s profile with no manual intervention.

This capability transforms any program that needs additional information beyond the initial application—from scholarships and grants to awards, fellowships, and corporate recognition programs.


The Challenge

Most programs require secondary or third-party information at some point in the lifecycle. Traditionally, these inputs are difficult to manage:

  • References are submitted late, inconsistently, and often via email attachments that require manual sorting.

  • Nominator–nominee workflows force nominators to complete lengthy submissions, reducing participation and accuracy.

  • Post-award or post-grant deliverables—scholarship renewals, fund disbursement forms, thank-you letters, progress reports, impact data—are scattered across inboxes and shared drives.

  • Deadlines become risky when third parties do not have adequate time to submit their pieces after applicants complete their own.

  • Administrators lack visibility and cannot easily track what has been requested, submitted, or still outstanding.

These inefficiencies create unnecessary friction for applicants, reviewers, administrators, and third-party contributors—and ultimately reduce program quality, data completeness, and impact visibility.


When to Use a Supplemental Form

You should only set up a supplemental form if advised by the Reviewr team. While powerful, this setup is only necessary in certain cases and requires backend configuration. If you're unsure whether your workflow qualifies, please reach out via the chat—we're happy to help you determine the best solution.

Use a supplemental form when:

  • A different user (not the original applicant) needs to submit part of the application

  • You are managing a multi-round or multi-phase process

  • You need to collect external documentation or input after a main submission is complete


How to Set Up a Supplemental Form

Follow these steps to properly configure a supplemental form:

1. Build Both Events

Create your two events:

  • Main (Parent) Event: This is where the original submission is completed.

  • Supplemental (Child) Event: This is where the additional user will complete their portion.

💡 Best Practice: Set the main event deadline first, then have the supplemental event deadline follow by a few days. This ensures the main form is completed before the supplemental form becomes active.

2. Add the “Supplemental Form” Question

In the form builder of the main event:

  • Add a “Supplemental Form” question type.

  • This serves as a placeholder to connect the child event.

You do not need to configure linking options here—this is done on the backend.

3. Contact the Reviewr Team to Link the Events

Once both events are built and the supplemental question is in place:

  • Reach out to the Reviewr team using the chat icon in the Admin Dashboard.

  • We'll connect the two events and configure the supplemental flow for you.

⚠️ This step is required. The link between parent and child events must be configured by Reviewr.


How the Link Works

When events are linked:

  • Reviewr uses event links on the backend to define how information flows between the parent and child events.

  • Once triggered, a Supplemental Invite is sent to the designated user, inviting them to complete their portion.

Invite Options:

  • Automatic (On Submit): Invite is triggered only after the main form is submitted (recommended).

  • Manual: Admin manually sends the invite—great for multi-round or selective workflows.

  • Automatic (On Save): Available but not recommended, as it can trigger too early and disrupt the process.


Date and Timing Tips

  • Parent event should start and end before the child event’s dates.

  • Leave a few days of buffer between the two deadlines.

  • This ensures applicants have time to finish their portion before others are invited.

Locked Information & Access

When a user submits a supplemental form, their First Name, Last Name, and Email become tied to their login credentials. If they change this information later, it will not change their access.

If updates are needed:

  • The user should notify the event admin.

  • The admin can request changes from the Reviewr team via chat
