03 / WHY APEX

Industry knowledge,
not a learning curve.

We have worked inside training organizations, so we understand the constraints you work under from day one.

01

Practical industry knowledge

We've held the licenses, stood the watch, and worked under exam security. You won't spend the first month teaching us what a JPM is.

02

Tailored, not templated

Your procedures are the specification. We build around how your site actually operates, not around a vendor's assumptions.

03

Reliable by design

Tools that instructors and evaluators can depend on mid-scenario and during exam week. Tested, documented, and built to be maintained.

04

Clearly defined deliverables

Every engagement starts with a written scope, acceptance criteria, and a defined list of what you will receive. No open-ended projects.

BUILT FOR HOW NUCLEAR SITES WORK

  • Exam security first

    We can scope and build without access to exam content, and we work under your exam security agreements when the project requires it.

  • Your network, your rules

    Deployable on-premises and on isolated networks, within your site's IT and cyber security requirements. No cloud dependency unless you want one.

  • Fits your QA program

    Documentation that supports your software quality assurance and configuration control procedures, from requirements to test records.

  • Traceable to the source

    Every requirement traces back to the procedure, standard, or regulation it comes from, so reviewers can follow the logic.

06 / COMMON QUESTIONS

Before you
reach out.

Is this a software product we can buy?

No. This is a professional services offering. We develop custom software and provide engineering and consulting support scoped to your organization's requirements. Some engagements build on proven approaches from previous work, but every deliverable is tailored to your site.

Do you need access to our exam materials?

Not to get started. We can scope and design grading and assessment tools without seeing exam content. If a project later needs controlled material, we work within your exam security agreements and procedures.

Can you work with our existing simulator and instructor station?

In most cases, yes. We start from the platform, instructor station, and supporting systems you already have and design around what they expose. We'll talk through your specific environment during the consultation.

Will AI tools send our data to the cloud?

Only if you choose that. We specialize in local AI that runs on your own hardware, including on isolated networks, and every AI solution is designed to comply with your company's AI policies. AI assists your staff. It never replaces the judgment of qualified instructors or evaluators.

Do you work on-site?

Most work is done remotely. On-site visits for requirements gathering, installation, or testing can be included in a project's scope where they add value.

How are projects priced?

After the consultation, we provide a written proposal with defined deliverables, schedule, and pricing. Nothing is required of you until you've reviewed it.

Who owns the software you build?

Ownership, licensing, and source code terms are agreed in writing before work begins.
