Calibration sessions help HR leaders and managers make fair, consistent, and transparent assessments of employee performance. Once the Manager reviews due by milestone has passed, you can begin holding calibration sessions.
In a calibration session, Contributors review manager ratings, discuss discrepancies, and make adjustments as needed to ensure participants receive unbiased evaluations.

Access and availability
⛔️ Required access to Best-Self Review® and Calibrations.
👥 This article is relevant to Review admins, Cycle collaborators, and Contributors.
📦 This feature is available in the Perform and Total Platform pricing packages.
Prerequisites to holding a Calibration Session
Before you begin, make sure these steps are complete:
- Custom attributes (optional): Add employee attributes (e.g., job level, last promotion date) if you want them visible during calibrations.
-
Create calibration sessions: Create a calibration session before you can hold one.
-
Schedule a meeting: Invite all contributors and appoint a moderator to keep discussions on track.
-
Check manager review status: Use the Review milestones section or the Review writers progress tracker report to see which reviews are complete. You can also download the "Review writers progress tracker" report to see which individuals have/haven't submitted reviews they're responsible for. Nudge managers if needed.
Tip
You can easily map employee data fields from your connected HRIS as custom attributes.
Access a Calibration Session
After the manager review deadline has passed, you can begin holding calibration sessions. Until then, calibrations will be greyed out and inaccessible so managers have time to submit their reviews.
- Click on Best-Self Review® in 15Five's main, left-hand navigation.
- Click on the name of the review cycle you want to access.
- You're now on the review cycle's overview page. From here, open the Calibrations tab using the navigation at the top of the screen.
- Click on the name of the calibration session you want to work on.
Calibration session page layout
A calibration session has four key tools:
Filters
-
People & Groups: Filter by hierarchy, group, or individual.
-
Review section: Choose which section (e.g., PMA, competencies, objectives) to view.
Note
You can only view answers given to questions in one review section at a time using the Talent Matrix and Calibration Table.
Talent Matrix
The Talent Matrix is a 9-box grid that lets you visualize manager ratings across two questions.
With the Talent Matrix, you can:
-
See which participants fall into possible answer options for any two questions
-
Drag and drop participants from one box to another to change their received answer
-
See the text responses provided for any answer for a participant by clicking on the participant's avatar. A drawer will open containing the text responses their manager(s) provided.
- View additional details about a participant, including custom attributes. Click a participant’s name to open their details drawer, which includes custom attributes, past review results, and a link to their full review.”
-
Filter the Calibration Table below to only display information about participants in select boxes
Calibration Table
The Calibration Table provides a detailed, row-by-row view of ratings.
With the Calibration Table, you can:
-
Apply filters to the Calibration Table using the "People & Groups" and "Review section" filters at the top of the page.
Note
You also have the option to filter the Calibration Table to only show information about participants in specific Talent Matrix boxes. To do so, click on the square in the upper, left-hand corner of any Talent Matrix box. Multiple boxes can be selected at a time.
-
Change review answers by hovering over the answer cell in the Calibration Table, clicking ..., and selecting the new answer.
-
Flag participants for discussion by checking the boxes to the left of their names, clicking the Actions button at the top of the Calibration Table, and selecting "Flag" or "Remove Flag" from the dropdown menu.
Once a change is made, the cell will become yellow and note the original answer (crossed out) and the calibrated answer. Changes will be reflected in the Activity Feed at the bottom of the page, as well as in the downloadable calibration session report. -
Remove participants from the session by checking the boxes to the left of their names, clicking the Actions button at the top of the Calibration Table, and selecting "Remove from session" from the dropdown menu.
-
View written responses and participant details by clicking on the answer cell. A drawer will open containing the text responses the participant's manager(s) provided.
Activity Feed
All changes made during calibration sessions are logged here. Contributors can:
-
Comment to provide context
-
@mention admins, collaborators, or contributors for discussion
-
Track why changes were made
Review and make changes to review answers
💾 Autosave:Changes in calibration sessions save automatically in real time. If someone leaves the session and returns later, all edits will still be there.
-
Use the Talent Matrix for a visual overview and broad trends.
-
Use the Calibration Table for detailed edits and discussions.
-
Any changes update in real time and appear in both tools.
-
If a participant appears in multiple calibration sessions, updates sync across all sessions.
Note
Changing an answer affects all manager reviews for that question (direct and additional managers).
View and provide context on changes
As changes are made in a calibration session, they're logged in the Activity Feed at the bottom of the page. Session contributors, Review admins, and Cycle collaborators can use this feed to provide additional context around what changes were made and why, as well as hold async discussions as needed. This information is extremely important, as it can be referenced for context as needed following a calibration session.
- Scroll to the Activity Feed at the bottom of the calibration session.
- Begin an async conversation using the "Add a comment" field.
- Start a comment thread on a change or comment by clicking the dialogue bubble icon under a change in the activity feed.
Tip
You can @mention Session contributors, Review admins, and Cycle collaborators in your comments.
Next Steps
When calibration is complete:
-
Lock the session before the Calibrations due by milestone.
-
Once locked, calibrated answers flow into manager reviews and review summaries.
-
Participants never see details of calibrations — only managers see original vs. updated ratings.

Frequently Asked Questions (FAQs)
Yes— you can download the Full progress report and refer to the "Calibration session status" column, which contains all calibration sessions an employee is a part of. This makes it easier for admins to audit and verify participant inclusion in calibration sessions without manually cross-referencing.
Calibrated answers will be reflected in participants' review summaries once the session is locked. In review summaries, managers can see what the original answer was and what it was changed to. Participants cannot see any information about their calibrated answers.
No. Participants cannot see any information about their calibrated answers.
You can remove people from a calibration session by checking the boxes to the left of their names, clicking the Actions button at the top of the Calibration Table, and selecting "Remove from session" from the dropdown menu.

No. However, a person's performance rating will update automatically when changes are made in the calibration session that impact their rating. This update will happen in real-time so contributors can see the impact of answer changes on an individual's rating.
If you see a white horizontal row for a participant while viewing the Calibration Table, that means their manager review wasn't submitted. Answers will only appear in the list once the manager review has been submitted.
If a participant is included in more than one calibration session, a number icon will appear on their avatar that indicates how many sessions they're a part of. Any changes you make to their review will be reflected immediately across all other calibration sessions they're involved in.
If a participant included in the calibration session had an additional manager in the review cycle, the additional manager's review results will also be shown in the calibration session. If a contributor makes a change to any manager review answers (whether from the direct manager or an additional manager review), it will be applied to all manager reviews for the participant.
Flags can be used to indicate that a participant's answers have already been discussed and finalized, that they're yet to be discussed, or that they require further discussion— whatever works for you! Just make sure your contributor teams understand what flags should be used for before kicking off calibration sessions.
