Getting prequalified: ISNetworld, Avetta and winning US work

For a growing share of US contractors, the gate to winning work is no longer just the bid — it is prequalification. Owners and general contractors increasingly require their subcontractors to be verified through a third-party network such as ISNetworld or Avetta before they can set foot on site. If you have ever been told "you need to be ISN-compliant to work for us," this guide is for you: what these networks actually check, how your safety numbers drive your grade, and how to get compliant without it swallowing your week.

What prequalification networks are

ISNetworld (run by ISN) and Avetta are the two best-known contractor prequalification and management platforms in North America, alongside others like Veriforce and Gold Shovel. Owners and GCs (the "Hiring Clients") subscribe to a network and set the requirements a contractor must meet to work for them. Contractors (subscribers) upload their information, and the network verifies it against those requirements and gives the hiring client a clear picture of who is qualified. In effect, the network is an outsourced, standardized version of the safety and insurance vetting a good GC would do anyway — which is exactly why it has spread so fast.

What they check

The specific requirements are set by each hiring client, but they cluster around a familiar set of things.

Written safety programs. The network will ask you to submit your written health and safety program and often assess it against a checklist of required elements and specific OSHA standards — HazCom, fall protection, LOTO, PPE, respiratory protection and so on, depending on your scope. A thin or generic program is where many contractors lose points.

Safety statistics. This is where numbers matter. Networks collect your OSHA 300A summaries and calculate rates from them — most importantly your Total Recordable Incident Rate (TRIR) and often your DART rate (Days Away, Restricted, or Transferred). They also collect your Experience Modification Rate (EMR) from your workers' compensation insurer. A high EMR or TRIR relative to your industry can drop your grade or flag you as higher risk to a hiring client.

Insurance. Certificates of insurance verifying coverage and limits — general liability, workers' compensation, auto and often umbrella — matching what the hiring client requires, with the right endorsements.

Training and certifications. Evidence that your workers hold the training the work requires — OSHA 10/30, competent-person cards, task-specific certifications — and that it is current.

Written responses and policies. Questionnaires covering your safety management practices — how you investigate incidents, manage subcontractors, handle drug and alcohol policy, and more.

How your grade is built

Most networks distill all of this into a grade or status per hiring client — a letter grade, a color, or a pass/needs-attention flag. The grade blends your verified documentation, your statistical performance (EMR, TRIR, DART against industry benchmarks) and the completeness of your account. Because different hiring clients set different requirements, you can be compliant for one client and not another, which is one of the things contractors find most confusing at first. The practical implication is that you keep a single, complete, current set of information and let the network map it to each client's rules.

The metrics that move the needle

Two numbers deserve special attention because they are calculated from data you already hold. TRIR is derived from your OSHA 300 log: the number of recordable cases times 200,000, divided by total hours worked. Keeping your 300 log accurate all year — not reconstructing it each February — directly protects this number. EMR comes from your workers' comp claims history over a three-year window; it rewards keeping people from getting hurt and returning injured workers to suitable duty promptly. Both reward exactly the behavior a good safety program produces, which is the point.

Getting and staying compliant

The mistake contractors make is treating prequalification as a one-time upload. Requirements change, insurance certificates expire, the 300A rolls over each year, training lapses, and hiring clients add new demands. An account that was green in March can slip to red by summer simply through documents aging out. Staying compliant is a maintenance job: keep your written program current, keep certificates and training in date, refresh your 300A and statistics each year, and respond promptly when a hiring client adds a requirement. Contractors who keep a live, organized compliance system spend minutes on this; those who scramble from a folder of PDFs spend days — and sometimes lose the job while they scramble.

Turning compliance into an advantage

Prequalification is often seen as a burden, but it cuts both ways. Once you are cleanly qualified, it is a moat: it filters out less-organized competitors and signals to owners that you are a low-risk choice. The contractors who win here are the ones who keep their safety program, training and metrics current as a matter of routine — and who can produce the evidence on demand. That is precisely the problem Complys is built to solve: it keeps the program, certifications, training and numbers these networks ask for current and audit-ready, and lets you share a live compliance profile with the GCs and owners deciding who to hire.
