Quality of Hire: How to Define, Measure and Improve It

0 min read

Every TA team can tell you how fast it hires and what each hire costs. Far fewer can tell you whether those hires turned out to be any good. That's a strange gap, because speed and cost only matter if the person you hired actually does the job well and stays.

Quality of hire is the metric that closes that gap. It's harder to measure than time to hire, because the answer only arrives months after someone joins. But it's the one number that tells the CHRO whether recruiting is really working.

This guide covers what quality of hire means, which signals to include, a simple composite formula with a worked example, when to measure, and what research says actually predicts better hires.

The short answer

To measure quality of hire:

1. Pick three or four signals that matter for the role, such as a 90-day performance rating, hiring manager satisfaction, time to productivity and 12-month retention.
2. Put each signal on the same 0–100 scale, then weight them by importance.
3. Average the weighted scores for each hire, then roll them up by role, source, recruiter or hiring channel.
4. Measure on a fixed timeline (30, 90, 180 and 365 days) so every cohort is compared at the same point.
5. Feed the results back into sourcing and selection, so you hire more from the channels and methods that produce your best people.

What is quality of hire?

Quality of hire is a measure of how much value a new employee adds to the organization after joining. It's usually calculated as a weighted score that combines job performance, retention, time to productivity and the hiring manager's satisfaction, measured at set points in the first year.

There's no single industry formula, and that's the main reason so few teams track it. "Quality" for a sales associate looks very different from quality for a data engineer. Each company has to decide what a good hire means for each role family before it can measure anything.

The other reason is timing. Time to hire is ready the day an offer is accepted. Quality of hire needs at least a few months of on-the-job data, which means TA has to borrow information from performance reviews and HR systems it doesn't usually own.

What goes into quality of hire

Most companies build their score from a short list of signals. SHRM's 2025 benchmarking found the three most common were interviews to evaluate performance, performance appraisal scores and retention rates. You don't need all of the signals below. Pick three or four that you can actually collect for every hire.

It also helps to record pre-hire signals for every candidate: assessment scores, interview ratings and source of hire. These aren't part of the quality score itself. They're what you compare the score against later to see which parts of your process predict good hires. A tool like an AI assessment agent keeps scores consistent across candidates, which makes that comparison much more reliable.

Pick different signals for different roles

• Campus and fresher roles: training or certification score, 90-day manager rating and 12-month retention. Output targets mean less in the first year.
• Sales and customer-facing roles: time to first deal or quota attainment, manager rating and retention.
• Technical roles: time to first meaningful contribution, manager and peer rating and retention.
• Leadership roles: goal attainment at 6 and 12 months, team retention under the leader and stakeholder feedback.

The quality of hire formula

The simplest reliable approach is a weighted composite. Convert each signal to a 0–100 score, give each one a weight, and add them up.

[
\text{Quality of Hire} = \sum_{i=1}^{n} w_i \times s_i
]

where:

[
\sum_{i=1}^{n} w_i = 100%
]

Here s is each signal's score out of 100 and w is its weight. To get a signal onto the 0–100 scale:

• Ratings: rating ÷ maximum rating × 100. A 4 out of 5 becomes 80.
• Retention: 100 if the person is still there at the checkpoint, 0 if they've left. Some teams pro-rate it instead, for example 8 months out of 12 becomes 67.
• Targets: actual ÷ target × 100, capped at 100. Reaching 90% of a ramp-up target becomes 90.

Once every hire has a score, you can report quality at the level that matters: the average score for a cohort, a hiring source or a recruiter. Many teams also track the share of hires above a set bar, such as hires scoring 70 or more ÷ total hires × 100.

A worked example

A company hires graduate trainees and agrees on four signals with these weights:

Hire A: (0.35 × 80) + (0.25 × 90) + (0.20 × 72) + (0.20 × 100) = 28 + 22.5 + 14.4 + 20 = 84.9

Hire B: (0.35 × 60) + (0.25 × 60) + (0.20 × 65) + (0.20 × 0) = 21 + 15 + 13 + 0 = 49

One score on its own doesn't tell you much. The value comes from rolling scores up. If this company found that hires from its hackathon averaged 82 while hires from general job boards averaged 61, it would know where to put next year's sourcing budget. (Those two averages are illustrative.)

When to measure: the first-year timeline

Quality of hire isn't one measurement. It builds up over the first year, and each checkpoint answers a different question. Measuring every hire at the same points is what makes cohorts comparable.

The 30-day and 90-day checks are early warnings: they catch problems while you can still fix onboarding or coaching. The 12-month score is the one to report to leadership and to use when comparing sources, recruiters and selection methods.

The practical challenge is collecting the data on time. Set up automatic reminders for hiring managers at each checkpoint, and store the results against each hire's candidate record in your applicant tracking system, so pre-hire scores and post-hire outcomes sit side by side.

What the research says

Most companies agree it matters, and most don't measure it. In LinkedIn's Future of Recruiting research, 88% of talent professionals said quality of hire would be very useful over the next five years, but only 48% were using it. SHRM's 2025 benchmarking found an even smaller share: just 20% of US organizations measure quality of hire, down from 27% in 2022.

Some selection methods predict performance far better than others. A 2022 meta-analysis by Sackett and colleagues in the Journal of Applied Psychology re-estimated how well common hiring methods predict job performance. Its key findings, as correlations with later performance:

Two things stand out for TA teams. Structured interviews came out on top, which means asking every candidate the same questions and scoring them on the same rubric. And job-specific tests, such as knowledge tests and work samples, beat general aptitude on its own. If you want to raise quality of hire, the cheapest place to start is usually your interview structure. An AI interview agent helps here because every candidate gets the same questions and the same scoring.

These numbers are averages across many studies. They tell you which methods tend to work, not exactly how well they'll work in your company. That's why measuring your own quality of hire against your own pre-hire scores matters.

How to improve quality of hire

Once you can measure it, improving it becomes a set of specific decisions rather than a vague goal.

Shift budget toward your best sources. Compare average quality scores by channel. Referrals, campus partnerships and hackathons often produce stronger hires than general job boards, but check your own data rather than assuming. If you're rebuilding your pipeline, an AI sourcing agent lets you search against the profile of your best past hires instead of waiting for whoever applies.

Fix the intake meeting. Many weak hires start with a vague brief. Agree on the must-have skills and what success looks like at 90 days before the role goes live, and score every candidate against that.

Structure your interviews. Same questions, same rubric, written feedback within a day. The research above makes this the highest-return change for most teams.

Test job skills, not just general aptitude. Work samples and role-specific tests predict performance better than a generic aptitude test alone.

Check which pre-hire scores actually predict. After a year, compare quality scores with the assessment and interview scores those people got as candidates. Keep the steps that predict and cut or redesign the ones that don't.

Don't let onboarding undo good hiring. A strong hire with a weak first 90 days can still fail. Give every new hire a clear plan, a buddy and regular check-ins with their manager.

Mistakes to avoid

• Using one signal on its own. A performance rating alone is skewed by the manager; retention alone ignores performance. Combine at least three.
• Changing the formula every quarter. Keep the weights fixed for at least a year, or you can't compare cohorts.
• Measuring too early. A 30-day score is useful as an early warning, not as the final answer.
• Blaming recruiting for everything. Quality of hire also reflects onboarding and management. Read it alongside those, not in isolation.
• Mixing very different roles. A blended score across interns and senior engineers tells you nothing. Report by role family.

Bringing it together

Quality of hire doesn't need a perfect formula. It needs three or four agreed signals, fixed weights and a fixed timeline. After two or three hiring cycles, you'll know which sources, tests and interview formats bring in your best people, and you can stop spending on the ones that don't.

Unstop keeps sourcing, assessment, interview and offer data for every candidate in one place, so pre-hire scores sit next to the outcomes you measure later. See how Unstop's hiring platform works.

Frequently asked questions

How do you measure quality of hire?

Choose three or four signals such as a 90-day performance rating, hiring manager satisfaction, time to productivity and 12-month retention. Convert each to a 0–100 score, apply weights that add up to 100%, and add the weighted scores together for each hire.

What is a good quality of hire score?

There's no universal benchmark because every company builds its score differently. Set your own baseline from your first full cohort, then aim to raise the average and the share of hires above a set bar, such as 70.

When should quality of hire be measured?

Take early signals at 30 and 90 days, a fuller score at 6 months and the final score at 12 months, when retention and a full performance cycle are available.

Who owns quality of hire, TA or HR?

TA usually owns the metric and the reporting, but the data comes from hiring managers, performance reviews and HR systems. It works best as a shared metric between TA, HR business partners and hiring managers.

Why don't more companies track quality of hire?

It takes months to measure, its definition differs by role, and the data sits outside the recruiting team's usual tools. SHRM's 2025 benchmarking found only 20% of organizations measure it.

Which hiring methods best predict quality of hire?

A 2022 meta-analysis by Sackett and colleagues found structured interviews had the highest average validity (.42), followed by job knowledge tests (.40) and work samples (.33).
