Formula
| Term | Meaning |
|---|---|
| Performance indicator | Average probation or first-cycle rating of the new hires as a percentage of the top score, for example 3.8 out of 5 = 76%. |
| Confirmation rate | New hires confirmed at the first probation review / New hires in the cohort x 100. Early leavers count as not confirmed. |
| 12-month retention | New hires still employed 12 months after joining / New hires in the cohort x 100. |
| Number of indicators | How many indicators are averaged, 3 here. Keep the same set every year. |
Worked example
A Kolkata BPO measured its 2025 hiring cohort of 120 agents. Managers rated their probation reviews at an average of 3.8 out of 5. Of the 120, 102 were confirmed at the first review, and 96 were still employed 12 months after joining.
- Performance indicator = 3.8 / 5 x 100 = 76%
- Confirmation rate = 102 / 120 x 100 = 85%
- 12-month retention = 96 / 120 x 100 = 80%
- Quality of hire = (76 + 85 + 80) / 3 = 241 / 3 = 80.33% (80.333 rounded to 2 decimals)
Choosing indicators you can measure
There is no single agreed formula for quality of hire, so pick a few indicators you can measure reliably for every new hire and keep them fixed. Probation ratings, first-time confirmation and 12-month retention are practical for most Indian companies because the data already exists. Some add hiring manager satisfaction, time to productivity or goal progress in the first review cycle. Weight the indicators equally unless you have a clear reason not to, and write the method down.
Comparing cohorts, sources and recruiters
Quality of hire is most useful as a comparison. Compare this year's cohort with last year's, and split the score by source of hire, recruiter, hiring manager and job family. If referral hires score higher than portal hires year after year, you know where to invest. Because the full score needs 12 months of data, pair it with faster signals, such as the probation confirmation rate, so problems surface before a whole year has passed.
- Quality of hire by source of hire.
- Quality of hire by recruiter and hiring manager.
- Each indicator shown separately beside the combined score.
Pitfalls in a combined score
A combined score can hide a weak indicator behind two strong ones, so always show the parts. Ratings are only comparable when managers use the scale the same way; a manager who rates everyone 4 inflates the score. Small cohorts swing widely, so do not judge a recruiter on three hires. And be careful not to blame recruitment for problems that begin after joining, such as a poor manager or an unrealistic target.
How to improve it
- Write a clear success profile for each role before advertising, and screen against it.
- Use structured interviews with the same questions and scoring for every candidate.
- Add a practical test or trial task that mirrors the real work.
- Share probation outcomes of their hires with recruiters every quarter.
- Put more effort into the sources whose hires score highest over two or more cohorts.
Tracking it in ZeniaHR
The inputs sit in ZeniaHR. Managers rate probation reviews 1 to 5 in My Team, and Probation & Confirmation records confirmations, extensions and not-confirmed decisions. Employee records hold joining dates and exits for the 12-month check, and Performance holds review cycles with a rating scale and weighted goals. ZeniaHR does not compute a quality of hire score, so bring the three indicators together in a spreadsheet and calculate.

How do you measure quality of hire?
Choose a few indicators you can measure for every new hire, such as average probation rating as a percentage, first-time confirmation rate and 12-month retention. Calculate each for the hiring cohort, then average them. For example, 76, 85 and 80 percent give a quality of hire of 241 / 3 = 80.33 percent.
When can quality of hire be calculated?
Only once enough time has passed for the indicators to exist. With 12-month retention in the formula, a cohort can be scored a year after its last member joined. For faster feedback, track the probation confirmation rate and probation ratings as early signals, and complete the score at 12 months.
Is quality of hire the recruiter's responsibility alone?
No. Recruiters shape who is selected, but hiring managers, onboarding and the first manager all affect early performance and retention. Use the score to improve the whole hiring process, and look at the separate indicators before drawing conclusions about any one person.
