Speed is an easy thing to measure. It’s natural to track how long it takes to close open roles, but time-to-fill is only one part of the staffing picture. Here’s a more complete view of what good staffing performance looks like and what to start measuring alongside speed.
The Problem with Optimizing for Speed Alone
Time-to-fill has become the default way most employers evaluate their staffing partner. It’s visible, it’s trackable, and it’s easy to compare. According to SHRM’s latest studies, the median time-to-fill for nonexecutive positions has come down to 39 calendar days.1 Although that number tells you how quickly a seat got filled, it doesn’t tell you anything about what happened next.
A placement that closes in 25 days and exits in 30 is expensive in ways that never show up in a time-to-fill report. The seat is empty again and the clock resets. When speed is the only thing being measured, the decisions that follow are based on an incomplete picture.
What Time-to-Fill Doesn’t Tell You
Time-to-fill is a useful starting point. But on its own, it leaves out the information that predicts whether your staffing investment holds.
Whether the candidate was the right fit
A fast placement can still be a wrong one. Fill speed says nothing about how well the candidate matched the role, the team, or the worksite environment.
What happened in the first 30, 60, or 90 days
Early exits are some of the most expensive events in a hiring cycle. SHRM data shows the median cost-per-hire for nonexecutive positions in 2026 sits at $1,300. When a placement fails early, that cost gets absorbed without a return, and the clock starts over.1
How much post-placement support was provided
Whether the staffing partner stayed close after Day One, followed up with the candidate, and flagged early warning signs isn’t reflected anywhere in a fill-speed number.
How the candidate experienced the process
Candidate satisfaction during placement directly affects engagement on the job. A recruiter who prepared someone well and stayed accessible after the offer produces a measurably different outcome.
The strength of a relationship between employer and staffing partner
Speed tells you how fast a seat got filled. It says nothing about whether the staffing partner will be showing up six months later or whether the relationship has any real depth behind it.
The Metrics That Actually Predict Staffing Success
A more complete picture of staffing performance requires looking beyond the placement date. Below are the indicators worth tracking alongside time-to-fill.
1. 90-Day Retention Rate
This is the single most useful measure of whether a placement actually worked. If a candidate is still in the role at 90 days, the fundamentals of the match were sound. If they aren’t, the time-to-fill number is irrelevant. Tracking 90-day retention by staffing partner gives employers a real accountability signal that fill speed can’t provide.

2. Quality of Hire
Quality of hire looks at how well a placed candidate performs in the role relative to what was expected. It includes attendance, productivity, supervisor feedback, and whether the hire is on track to grow. It’s a harder metric to quantify than speed, but it’s the one that most directly reflects whether the staffing process is working.
3. Candidate Engagement and Satisfaction
Engagement directly influences both performance and retention.2 A candidate who felt supported, informed, and prepared during the placement process is more likely to show up engaged and stay longer. Tracking how candidates experienced the process, from first recruiter contact through the first 90 days, tells employers something important about the quality of the staffing relationship they’re in.

4. Post-Placement Communication Frequency
How often does your staffing partner check in after a candidate starts? If the answer is “rarely” or “only when something goes wrong,” that’s a gap worth noting. Regular post-placement contact is one of the clearest signals that a staffing partner is genuinely invested in what happens after the placement.
5. Cost-Per-Successful-Hire
Standard cost-per-hire figures capture what it costs to fill a role. Cost-per-successful-hire captures what it costs to fill a role with someone who stays. It factors in the cost of any failed placements before the right fit was found. Tracking this number over time reveals whether your staffing partner is improving the efficiency of your hiring investment, or just moving faster through a cycle that keeps repeating.
