The 70% Rule in Hiring: A Home Services Owner’s Guide
TL;DR

TL;DR: The 70% rule says you should hire a candidate when they meet roughly 70% of your criteria instead of waiting for a perfect match, then close the remaining 30% through training. For home services owners it speeds up hiring and cuts vacancy costs, but it only works when the right 70% is non-negotiable behavioral fit, not just skills. Use the 70% rule on the resume and add a behavioral fit signal on top.

Before you start

Before you run the 70% rule on your next open role, have these three things ready:

  • A written role description that separates true day-one requirements from nice-to-haves, so you know which 70% you are protecting.
  • A way to run a structured phone screen, so communication and basics get checked the same way for every candidate.
  • A behavioral signal or assessment you can put in front of interviews, so you catch fit problems before you burn half a day on someone who was never going to work out.

What the 70% rule actually says

If you’ve ever sat through three rounds of interviews, finally found “the one,” and then watched them ghost you for a $2/hr counter-offer, you already know why the 70% rule exists. Most home services owners aren’t losing money because they can’t find anyone. They’re losing money because they’re waiting on a unicorn who checks every box on a job description that was copy-pasted from a 2018 Indeed template.

The 70% rule (sometimes called the 70/30 rule) is straightforward: if a candidate meets roughly 70% of the requirements on your job description, hire them. Don’t wait for 100%. The remaining 30% is the gap you close through onboarding, training, ride-alongs, and time on the truck.

The rule has been floating around recruiting circles for years. It’s commonly discussed by executive search practitioners and talent leaders on LinkedIn who got tired of watching companies chase “purple squirrels” while their pipelines bled out. Treat the “70%” as a practical heuristic rather than a precise research finding; the exact number matters less than the discipline of separating must-haves from nice-to-haves.

The math behind it is simple. If your average open role costs you somewhere between several hundred and close to a thousand dollars a day in lost revenue, missed calls, overworked techs, and overtime (this varies widely by trade, market, and ticket size), and time-to-fill in the skilled trades is widely reported to run well over a month, often 40 days or more, then every extra week you spend hunting for a “perfect” candidate is costing you four figures, easy. Hiring a 70% candidate today and training the gap usually beats hiring a 95% candidate six weeks from now. Whatever threshold you set, apply it consistently to every candidate for the role: inconsistent application of hiring criteria is one of the most common sources of discrimination claims.

Some recruiters frame this as 70/30: hire 70% on what they can already do, 30% on what they can learn. Others frame it as 70% skills, 30% culture/attitude. Either way, the spirit is the same: stop optimizing for the resume and start optimizing for the trajectory.

The trap: when the 70% rule creates expensive bad hires

The 70% rule was designed to fight “hiring perfectionism,” but in the wrong hands, it becomes a license to lower the bar and call it strategy. The most common ways owner-operators get burned:

They drop the 70% on the wrong 70%. They hire someone who has the technical skills but can’t talk to a homeowner, won’t follow a process, or hates being on a ride-along. Skills can be trained. Attitude on someone’s couch can’t.

They confuse “trainable gap” with “red flag.” A missing EPA cert is a trainable gap. Three jobs in 18 months with no explanation is not a gap, it’s a pattern.

They skip the behavioral check entirely. This is the big one. The 70% rule is a resume rule. It says nothing about whether this human will actually show up on time, talk to a customer like a professional, or stay long enough to be worth training. Leadership IQ’s Hiring for Attitude research (Mark Murphy, Wiley, 2011) remains the canonical source here: it found that the majority of new-hire failures are driven by attitude and coachability, not technical skill gaps.

The ugly truth is that most bad hires in the trades aren’t bad because they lack skills. They’re bad because of behavior: punctuality, accountability, communication, follow-through, conflict style on a job site. Resumes don’t show any of that. And the 70% rule, applied naked, doesn’t fix it.

The fix: 70% skills + a behavioral fit signal

This is the version that actually works. Use the 70% rule on the resume: be honest about which technical requirements are floors versus nice-to-haves, and stop disqualifying people for missing the nice-to-haves. Then add a second layer: a fit check before you spend three interviews on someone. (If you’ve ever wondered whether personality tests for hiring belong in a service business, this is exactly where the question earns its keep.) When you combine “this person has 70% of the skills” with “this person scores well on fit for this seat,” you stop trading slow hires for fast bad hires.

The all-in cost of a bad hire (rehire, training, lost revenue, and customer fallout) is commonly estimated at roughly a third of first-year earnings, and can run higher for senior roles. The U.S. Department of Labor and groups like SHRM are often cited for general support on this point, though published figures vary widely and should be treated as estimates rather than precise numbers. Either way, you can’t afford to use the 70% rule without the behavioral half. The rest of this guide is the seven-step version you can run on Monday morning.

Step 1: Cut your job description down to the real floor

Take your current job description and force every line into a bucket so you can see what actually matters.

How to do it

List every requirement. Then mark each as must-have on day one, must-have by day 30, or nice-to-have ever. If more than five things are in the first bucket, you’re being unrealistic. Most service roles have 3-4 true day-one requirements: license/cert where legally required, basic skill floor, clean driving record, and the ability to reliably arrive at scheduled job sites on time.

Why this works

Most owners write job descriptions like wish lists, every skill they've ever wished a tech had, plus three certifications they don't actually need. Forcing each line into a bucket is what turns the 70% rule from a slogan into a decision you can defend.

Step 2: Define the 30% you'll actually train

Decide, in writing, exactly how you will close the gap before you ever extend an offer.

How to do it

Be specific. “We’ll train them up” is not a plan. “They’ll ride with our senior tech for 30 days, hit these five skills by day 60, and pass a sign-off ride at day 90” is a plan. If you can’t write the training plan, you can’t honestly invoke the 70% rule.

Why this works

The 70% rule is only a shortcut because the other 30% is a commitment. A written plan is the difference between hiring on trajectory and quietly lowering the bar.

Step 3: Add a behavioral filter before the first interview

Put a fit check in front of the interview so you stop spending time on people who were never going to work out.

How to do it

Resume screens identify skills. Phone screens identify communication. Neither identifies behavioral fit for a service seat. Put a structured behavioral assessment in front of the interview, not behind it, so you stop interviewing people who were never going to work out anyway. What “behavioral fit” means in practice for a home services crew comes down to a few questions:

  • Do they tend to follow established processes, or do they prefer to improvise?
  • How have they handled pressure on a stuck job in the past, escalating, or hiding?
  • Do their past roles show consistent patterns of positive customer engagement?
  • Have they owned mistakes when one cost their employer money?
  • Does their track record suggest they’ll still be on the truck six months from now?

Why this works

A fit signal answers those questions before you've burned half a day on interviews, which is where the 70% rule's biggest failure mode (a fast bad hire) gets caught. Some jurisdictions regulate automated employment decision tools and may require bias audits, candidate notice, or consent. If you use a third-party background check or assessment vendor that qualifies as a consumer reporting agency, FCRA requires written candidate consent and proper adverse-action notices. Confirm local requirements and your specific obligations with counsel before using any assessment as part of your hiring process.

Step 4: Interview against the must-haves, not the wish list

Run the interview against the short list you already built, not the wish list you cut.

How to do it

Walk into the interview with your 3-4 day-one must-haves and your behavioral signal. Don’t ask trivia. Ask: Tell me about a time a customer was angry when you showed up. Walk me through what you did. Then shut up and listen.

Why this works

When you interview against the real floor instead of the wish list, you stop disqualifying good candidates on nice-to-haves and you keep the conversation on the behaviors that actually predict whether they'll succeed on the truck.

Step 5: Reference-check on behavior, not duties

Use references to confirm behavior, not just employment dates.

How to do it

Anybody can confirm “yes, he worked here.” What you actually need: Would you put him back on your truck tomorrow? Why or why not? Silence after that question tells you everything.

Why this works

Duties are already on the resume. The behavioral question forces a former employer to take a position, and the hesitation (or enthusiasm) tells you what a job title never will.

Step 6: Make the offer fast

Once a candidate clears your bar, move before someone else does.

How to do it

If they pass the 70% bar, the behavioral check, and the references, move. One of the most common reasons good candidates ghost is a slow offer; in tight trades labor markets, the people who clear your bar are clearing other employers’ bars at the same time. Same-week offers close. Two-week offers don’t.

Why this works

The 70% rule exists to cut the cost of waiting. A slow offer hands that saved time back, and hands your best candidate to a competitor who decided faster.

Step 7: Build the first 90 days like you mean it

Treat the first 90 days as the training commitment that the 70% rule depends on.

How to do it

The 70% rule is a hiring shortcut backed by a training commitment. If you skip the training, you didn’t use the rule, you just lowered the bar. A real 90-day plan is what makes the 30% an investment instead of a gamble.

You’ll know the 70% rule is working when:

  • You reject most resumes at the screen instead of dragging marginal candidates through three interviews.
  • Your time-to-fill drops, because you stop waiting on a perfect match that doesn’t exist.
  • 90-day retention climbs, because the behavioral half is catching the fit problems that used to cause early quits.
  • You can defend every hire decision in writing, because the must-haves and the training plan were set before the first interview.

If retention isn’t improving, the usual culprit is dropping the 70% on the wrong 70%: you kept nice-to-have technical requirements as floors while quietly skipping the behavioral check. Tighten the fit signal, not the skills bar.

Frequently asked questions

What is the 70/30 rule in hiring?

The 70/30 rule is the same idea as the 70% rule, framed slightly differently: hire when a candidate has 70% of what the role requires today, and plan to develop the remaining 30% through onboarding and training. Some practitioners frame the 30% as “culture and attitude,” others as “trainable skills.” The point is the same: stop waiting for a 100% match that doesn’t exist, and start hiring on trajectory.

Is the 70% rule the same as "hire for attitude, train for skill"?

Close, but not identical. “Hire for attitude, train for skill” is a philosophy. The 70% rule is a quantitative shortcut you apply to a job description. They work best together: use the 70% rule to stop disqualifying people on resume nice-to-haves, and use “attitude over skill” to make sure the 70% you’re hiring includes the right behavioral floor.

Should home services actually use the 70% rule?

Yes, with the behavioral layer attached. The trades have brutal time-to-fill numbers and brutal turnover, which means the cost of waiting and the cost of a bad hire are both high. The 70% rule lowers the first cost. A behavioral fit assessment like RightSeat lowers the second. Skip either half and the math falls apart.

What's the biggest mistake when applying the 70% rule?

Dropping the 70% on the wrong things. Owners often keep nice-to-have technical requirements as floors (specific brand experience, a cert you don’t legally need) while quietly dropping the things that actually predict success: punctuality, customer communication, accountability, fit with how your crew runs. Be ruthless about which 70% you’re protecting.

How fast should I make an offer once a candidate clears the 70% bar?

Fast, within days, not weeks. In a tight labor market, the candidates who clear your bar are clearing other people’s bars too. Once they pass the skills floor, the fit check, and the reference call, the next step is an offer, not another interview. (For owners running EOS, the right person, right seat assessment gives you the language to defend that same-week call to your leadership team.)

The 70% rule speeds up hiring only when the right 70% is non-negotiable behavioral fit, not just skills. Cut the job description to the real floor, write the training plan for the 30%, put a fit check in front of your interviews, move fast on the candidates who clear the bar, and build a real first 90 days. Do that and you stop trading slow hires for fast bad hires.
