TLDR
Avetta requires contractors to submit three core safety metrics during prequalification: Total Recordable Incident Rate (TRIR), Days Away Restricted or Transferred (DART) rate, and Experience Modification Rate (EMR). There is no universal passing threshold because each hiring client sets its own acceptable limits. Contractors must also upload three years of OSHA 300/300A logs and complete an annual update by March 31. This guide covers every formula, benchmark, and process step you need to stay compliant.
Understanding Avetta safety statistics requirements is the difference between winning work and getting filtered out before anyone reads your bid. The platform serves over 130,000 businesses across 120 countries, and the contractors who struggle most are the ones who treat safety statistics as a paperwork exercise instead of a quantified risk profile that hiring clients evaluate automatically.
This guide covers every safety metric Avetta requires, how each one is calculated, what current industry benchmarks look like, and what to do when your numbers fall outside a client’s threshold. Bookmark it. You’ll need it every year before your annual update.
If you need hands-on help navigating Avetta’s requirements, ESR’s Avetta compliance consultants work with contractors through the entire process.
Quick Summary: What Are Avetta’s Safety Statistics Requirements?
Avetta requires contractors to submit three primary safety metrics during prequalification:
Total Recordable Incident Rate (TRIR): Measures all work-related injuries and illnesses per 100 full-time workers. (Formula:
[Recordable Incidents × 200,000] / Total Hours Worked)Days Away, Restricted, or Transferred (DART) Rate: Measures severe incidents that resulted in lost work time, job restrictions, or transfers. (Formula:
[DART Cases × 200,000] / Total Hours Worked)Experience Modification Rate (EMR): Evaluates your workers’ compensation claims history relative to industry peers, verified via an official rating letter from your carrier.
Key Deadlines & Requirements: Contractors must upload 3 years of OSHA 300 and 300A logs and complete an Annual Update by March 31. There is no single universal passing score—each hiring client sets its own thresholds (typically TRIR below 2.0, DART below 1.5, and EMR at or below 1.0).
What Are Avetta Safety Statistics Requirements?
Avetta is a contractor prequalification platform that hiring clients (general contractors, owners, developers) use to evaluate subcontractor risk before awarding work. As part of that evaluation, Avetta grades contractors across several weighted categories: insurance certificates, safety statistics, written safety programs, training records, and OSHA recordkeeping.
The safety statistics portion specifically requires three quantitative metrics:
TRIR (Total Recordable Incident Rate)
DART Rate (Days Away, Restricted, or Transferred)
EMR (Experience Modification Rate)
These metrics are submitted alongside supporting source documents: your OSHA 300 and 300A logs (typically three years’ worth) and an EMR letter from your workers’ compensation carrier.
Here’s what most contractors miss: there is no single Avetta threshold that applies to everyone. Each hiring client on the platform sets its own requirements. A contractor can be fully compliant for Client A while simultaneously failing Client B’s criteria on the same account. The services you select in your Avetta profile also trigger additional requirements in safety statistics, service-specific programs, and client-specific questions.
This client-specific structure is similar to how ISNetworld handles its requirements. Understanding the pattern across platforms saves time and prevents surprises.
TRIR: Total Recordable Incident Rate
What It Is
TRIR reflects the number of recordable injuries per 100 full-time workers during a one-year period. A recordable incident is any work-related injury or illness that results in death, loss of consciousness, days away from work, restricted work activity, transfer to another job, or medical treatment beyond first aid.
The Formula
(Number of Recordable Incidents x 200,000) / Total Hours Worked
The 200,000 figure represents the total number of hours 100 employees would log in 50 weeks at 40 hours per week. OSHA established this as the standard baseline.
Current Benchmarks
According to the Bureau of Labor Statistics Survey of Occupational Injuries and Illnesses (SOII) for 2024, released in January 2026:
Construction TRIR: 2.2 per 100 full-time equivalents
All private industry TRIR: 2.3 per 100 FTEs (the lowest in the BLS series dating back to 2003)
What Avetta Clients Typically Require
Common general contractor thresholds fall between 1.0 and 2.0, depending on project risk level. A TRIR below 2.0 is generally considered good for construction. Some owner-operators on high-risk projects (refineries, chemical plants, large commercial builds) require a TRIR below 1.0.
Avetta calculates your TRIR from the OSHA 300 log data you submit and compares it against BLS industry average rates for your specific NAICS code. A TRIR above the industry average reduces your score.
The Small Contractor Problem
TRIR is less stable when calculated from a small workforce or limited exposure hours. For a company with 10 employees, a single recordable incident can spike the rate dramatically, making performance appear far worse than a larger company with the same incident. Avetta’s own research acknowledges this limitation. Data examining 17 years of records covering more than 3.2 trillion work hours found that recordable incidents occur randomly across space and time, and at least 100 months of data is needed for meaningful predictive power.
This matters because contractors with fewer than 20 employees account for 67% of all construction-related fatalities despite representing just 37% of the total construction workforce. If you’re a small contractor dealing with a TRIR spike from a single incident, the variance request process (covered below) is your path forward.
DART Rate: Days Away, Restricted, or Transferred
What It Is
The DART rate measures the number of incidents serious enough to result in time away from work, restricted duties, or a job transfer per 100 full-time workers. It is a subset of TRIR that focuses specifically on more severe injuries.
The Formula
(Number of DART Cases x 200,000) / Total Hours Worked
A DART case is any incident recorded on your OSHA 300 log with a check in column H (days away from work) or column I (job transfer or restriction). Understanding which columns apply is critical. Errors here are common and directly affect your Avetta score. For a detailed breakdown of OSHA 300 log requirements, ESR’s recordkeeping guide walks through each column.
Current Benchmarks
From the BLS 2024 SOII data:
Private industry average DART rate: 1.4 per 100 FTEs
Construction average DART rate: 1.3 per 100 FTEs
DART-to-TRIR Severity Ratio
In construction, the DART-to-TRIR ratio is approximately 0.59 (1.3 / 2.2). This means roughly 59% of all recordable incidents in construction are severe enough to involve time away, restricted duty, or transfer. A company whose DART-to-TRIR ratio is significantly higher than the industry norm may face additional scrutiny, as it signals that when incidents do happen, they tend to be more serious.
How Avetta Uses DART Alongside TRIR
Avetta evaluates DART and TRIR together. A contractor could have a TRIR that meets a client’s threshold but a DART rate that exceeds it, or vice versa. Common operator thresholds for DART range from 0.5 to 1.5 depending on the operator and contract type.
Practical Example: How a Single Incident Impacts a Small Contractor
Small contractors face severe mathematical volatility under Avetta’s formulas. Consider a specialty subcontractor with 15 employees logging 30,000 total hours in a calendar year:
0 Incidents:
TRIR = (0 × 200,000) / 30,000= 0.00 (Fully Compliant)1 Minor Injury:
TRIR = (1 × 200,000) / 30,000= 6.67 (Fails most client thresholds)
Because client limits usually range between 1.0 and 2.0, a single recordable injury pushes this contractor’s rate to more than three times the acceptable limit. In this scenario, the contractor cannot change the math—they must submit a Variance Request with documented corrective actions to gain approval.
EMR: Experience Modification Rate
What It Is
The Experience Modification Rate is a number calculated by your state’s workers’ compensation rating bureau (often NCCI or a state equivalent) that reflects your company’s claims history relative to industry peers. A rate of 1.0 is average. Below 1.0 means better than average. Above 1.0 means worse.
You don’t calculate your EMR. Your workers’ compensation carrier provides an EMR letter, which you upload to Avetta.
Common Avetta Client Thresholds
Most Avetta hiring clients set a maximum acceptable EMR of 1.0 or 1.25. Contractors with an EMR above 1.0 get flagged. Those above 1.2 are often automatically rejected by safety-conscious clients.
For a deeper explanation of how experience ratings work, ESR’s guide on understanding experience rating covers the calculation methodology and what drives the number up or down.
The Three-Year Rolling Window
EMR uses a rolling three-year claims window, which creates a lag effect that frustrates many contractors. A rising TRIR often predicts a rising EMR 12 to 18 months later because workers’ compensation claims from recordable incidents enter the NCCI system and take time to flow through the rating calculation.
Here’s a practical scenario: a GC in commercial construction requires an EMR below 1.0, a TRIR below 2.0, verified OSHA 30 credentials for your superintendent, and a site-specific safety plan. If your EMR is 1.15 because of a single workers’ comp claim from 18 months ago, you may not meet their threshold, even if your crews have worked 80,000 hours without a recordable since then. The EMR follows you for three years.
Understanding how your EMR is calculated and tracked across rolling three-year windows helps you spot trends early and take proactive steps before elevated rates impact your prequalification status across hiring clients.
OSHA 300 and 300A Logs in Avetta
What Avetta Needs
Avetta typically requires three years of OSHA 300 and 300A data. These logs are the source documents from which your TRIR and DART are calculated. Without accurate logs, your safety statistics are wrong from the start.
Corporate vs. Divisional Reporting
When submitting, Avetta and your clients recommend selecting “Corporate” and providing OSHA logs for your entire company. If you report for your entire company, select Corporate. If your company has distinct divisions, regions, or sites with separate OSHA logs, you can specify that structure, but be consistent year over year.
OSHA Posting and Submission Requirements
The OSHA 300A summary log must be posted in the workplace from February 1 through April 30 of the year following the recorded incidents. Separately, OSHA’s final rule effective January 1, 2024, requires establishments in designated high-hazard industries with 100 or more employees to electronically submit data from OSHA Forms 300 and 301 to OSHA annually, in addition to the previously required 300A summary.
OSHA Electronic Submission & Avetta Audit Alignment
Under OSHA’s electronic recordkeeping rules, establishments with 100 or more employees in designated high-hazard industries must submit detailed Form 300 and Form 301 data electronically alongside their Form 300A summary.
Why this matters for Avetta: Avetta auditors and hiring clients regularly cross-reference public OSHA electronic disclosures against your uploaded PDF logs. Ensure that the total hours worked, employee counts, and injury numbers submitted to OSHA match your Avetta profile to the single digit. Discrepancies between public OSHA data and Avetta entries trigger automatic compliance flags and program audits.
Retention
Employers must retain OSHA 300 logs, the privacy case list, the annual summary, and the 301 Incident Report forms for five years following the end of the calendar year the records cover. This aligns with Avetta’s three-year lookback, but keep five years on file regardless.
If OSHA recordkeeping accuracy is a concern, ESR’s recordkeeping services help contractors maintain compliant logs year-round.
How Avetta Scores Your Safety Statistics
Avetta uses a composite scoring model that weights incident history, safety program documentation, insurance, and worker training records. The specific weighting depends on the hiring client’s configuration. Avetta allows clients to adjust which criteria matter most for their particular risk profile.
TRIR and DART are calculated from your OSHA 300 log data and compared against BLS industry average rates for your NAICS code. A TRIR or DART rate above the industry average will reduce your score.
The Color-Coded Status System
Green (Compliant): All baseline standards met. Safety programs approved, insurance verified, performance metrics below thresholds. Fully eligible to bid and work.
Amber (Conditional/Warning): A minor variance or an upcoming expiration has triggered a warning. You can still work for most clients, but action is needed soon.
Red (Non-Compliant): A critical failure. This can be triggered by a failed safety program audit, expired OSHA logs, EMR or TRIR exceeding client caps, or completely missing an annual update deadline.
Automatic Filtering
This is the part that catches contractors off guard. Your grade is a risk score, and risk scores that fall below a client’s threshold get filtered out automatically. There’s no phone call, no appeal triggered from your side. Hiring clients set thresholds for TRIR, DART, and EMR, and if your numbers are above their limits, no amount of paperwork will make you compliant for that client.
Practitioners in contractor forums have noted that Avetta periodically updates how sub-scores weight relative to each other in the compliance summary. A contractor who was passing in one quarter can show up in red the next quarter without changing a thing on their side. Staying proactive with updates is the only defense.
The Annual Update: When and How to Submit
The March 31 Deadline
An Avetta annual update is the yearly process where suppliers submit updated company information, certifications, insurance documentation, and safety statistics. This includes historical safety data, details on workplace injuries and illnesses, and any safety improvements made over time.
The deadline is March 31. Missing it can result in temporary removal from the platform or permanent rejection by a hiring client.
Step-by-Step Submission
Log in to Avetta Connect
Click “Compliance” on the sidebar
Click “Current Tasks”
Click “Company Regulatory Information” and view Annual Update tasks
Click “Get Started” next to the current year’s Annual Update task
Fill out and upload all required information (OSHA logs, hours worked, incident counts, EMR letter)
Click the green “Submit” button
If a task is locked, you’ll need to contact Avetta Support directly to have it unlocked for editing. This is a common source of frustration, especially close to the deadline.
Best Practice
Start early. Do not wait until late March. Gather your OSHA 300A summaries, confirm your total hours worked, verify your EMR letter is current, and have your safety coordinator review the data before submission. Errors in hours-worked entries are one of the most common mistakes. A wrong number in the hours field changes your TRIR and DART calculations entirely.
Practitioners on Reddit and in contractor forums report that most safety managers assume their written programs are the problem when they get flagged. The real problem is often training documentation. Avetta auditors rarely reject a contractor for having a mediocre confined space program. They flag contractors because the program says “all employees receive annual retraining” and the training records show 40% completion.
Variance Requests: What To Do When Your Numbers Are Above Threshold
When to File
A variance request is the formal process for explaining non-standard situations to Avetta. Common scenarios include:
Your EMR is above 1.0 because of a single incident
Your TRIR spiked due to one recordable on a small workforce
Your company is too new to have three years of OSHA history
A legitimate circumstance prevents you from providing a specific document
What Works
Variance requests that succeed include detailed context and supporting documentation. If you had a recordable incident but took documented corrective action (revised procedures, additional training, equipment changes), explain the spike with specifics. Attach the corrective action plan, the training sign-in sheets, the equipment purchase orders.
What Doesn’t Work
Generic explanations get denied. “We had a bad year but we’re better now” won’t cut it. The variance approval process is driven by the hiring client, not by Avetta itself. Various tasks including insurance requirements, TRIR, EMR, and safety statistics related to years in business often require manually requesting a variance.
If your numbers are above threshold and you’re not sure how to build a convincing variance case, this is where outside help pays for itself. A well-documented variance with corrective actions attached has a much higher approval rate than a contractor trying to explain away poor numbers without evidence.
For contractors who’ve received an OSHA citation that contributed to their TRIR spike, ESR’s guide on OSHA citation response steps outlines the process for getting your house in order.
Why Safety Statistics Alone Don’t Tell the Whole Story
Avetta itself has published research acknowledging the limitations of TRIR, DART, and EMR as standalone measures. These are lagging indicators. They tell you what already happened, not what’s about to happen.
Traditional incident rates are less stable when calculated from a small workforce or limited exposure hours. For small organizations, a single incident can cause a sharp increase that makes performance appear significantly worse than larger companies. The research examining 17 years of data from 10 construction companies found that incidents occur randomly and that few organizations have the data volume needed for statistically meaningful predictions.
The Platform Is Evolving
Avetta has been moving toward supplementary evaluation tools, including a Safety Maturity Index and Culture Maturity Index, that attempt to measure leading indicators. These assess whether a contractor has proactive safety systems in place, not just whether they’ve avoided recordables.
This aligns with a broader industry shift. If your company wants to move beyond reactive compliance toward a systems-based safety approach, safety management system consulting can help build the infrastructure that improves both your Avetta scores and your actual injury prevention.
The Data Supporting Prequalification
Despite the limitations of individual metrics, the aggregate data is compelling. According to Avetta’s 2025 Insights and Impact Report, fully compliant suppliers demonstrated a 62% lower fatality rate than non-compliant suppliers (1.19 vs. 3.12 per 100,000 workers). In the United States, suppliers participating in prequalification see roughly a 20% reduction in TRIR, DART, and lost workday case rates compared to BLS averages. Companies that add supplier audits to their safety programs see reductions as high as 52%.
Organizations with 10 or more years of engagement in Avetta’s programs saw a 45% reduction in fatality rates. The longer companies participate, the safer they become, with some yielding a 7% to 12% reduction in workplace safety incidents year over year.

Frequently Asked Questions
What TRIR does Avetta require?
There is no universal TRIR requirement across Avetta. Each hiring client sets its own threshold. Common construction thresholds range from 1.0 to 2.0. Your TRIR is compared against the BLS industry average for your NAICS code, and exceeding that average will reduce your compliance score.
What if my EMR is above 1.0?
An EMR above 1.0 will flag your account for many hiring clients. If the elevated rate is due to a specific, explainable circumstance (a single claim, a one-time incident), submit a variance request with documented corrective actions. If the hiring client approves it, you can still qualify. But some clients auto-reject above 1.0 with no exceptions.
How many years of OSHA logs does Avetta need?
Three years of OSHA 300 and 300A logs is the standard requirement. Keep five years on file regardless, as OSHA’s retention rules require it.
Can I update my safety stats after the annual update is approved?
Locked tasks in Avetta require contacting Avetta Support to reopen. If you discover an error after submission, reach out to support immediately. The longer inaccurate data sits in your profile, the more clients see it.
What’s the difference between TRIR and DART?
TRIR captures all recordable incidents. DART is a subset that only counts incidents resulting in days away from work, restricted duty, or job transfer. DART measures severity while TRIR measures frequency. Avetta evaluates both, and failing either one can drop your compliance status.
Do I need to be on both Avetta and ISNetworld?
It depends on your clients. Many contractors maintain accounts on multiple platforms. Practitioners in contractor forums describe holding memberships across five or more prequalification platforms, calling it the cost of doing business. If you’re comparing the two, ESR’s breakdown of ISNetworld vs. Avetta covers the key differences.
Why did my Avetta score drop without any changes on my side?
Avetta periodically adjusts how sub-scores are weighted in the compliance summary. A contractor passing in one quarter can show up in red the next without changing anything. Additionally, expired insurance, an approaching annual update deadline, or a client changing their threshold requirements can all trigger a status change.
How do I get started if I don’t have an Avetta account yet?
If a hiring client has told you to “get on Avetta,” you’ll need to create an account, select your services, and begin uploading documentation. ESR’s guide on Avetta account setup walks through the process step by step.
Meeting Avetta safety statistics requirements is not a one-time task. It’s an annual commitment that directly affects your ability to bid on and win work. The contractors who stay ahead are the ones who treat their TRIR, DART, and EMR as living numbers, tracked monthly, not scrambled together in late March.
