We changed how we score your tests. Here's why.

There's a specific kind of anxiety that comes with seeing a number on a screen and not being sure what it's measuring.

I've watched it happen more times than I can count: a pilot finishes a practice session, sees a score labeled "Clinical Risk Indicator," and spends the next hour reading things into it that simply aren't there. Am I at risk? Is this what the real test shows? Does this mean I'm going to fail?

That label was doing work we never intended — and for pilots navigating HIMS evaluations or working directly with aviation medical examiners, that kind of ambiguity is the last thing you need. So we changed it.

Starting now, PilotPrep's in-app composite score is called the Training Risk Estimate. The underlying calculation hasn't changed at all. What changed is the name — and the name matters more than you might think.

What the old name was getting wrong

The score we'd been calling the "Clinical Risk Indicator" was modeled on the CogScreen-AE's official Logistic Regression Probability Value, or LRPV. The LRPV is a composite score produced by a licensed neuropsychologist using Vista Partners' proprietary regression weights, calculated across all nine CogScreen-AE subtests under standardized clinical conditions. It's a serious clinical instrument, and interpreting it requires clinical training.

PilotPrep's version is something different: a training signal built on published professional pilot normative data, using equal weights across seven subtests. It gives you real, evidence-grounded information about where your practice performance sits relative to working pilots. That's genuinely useful. But calling it a "Clinical Risk Indicator" implied it was doing the same thing the official LRPV does — and it isn't.

The problem with false precision isn't that it flatters you. It's that it misleads in both directions. Some pilots saw a low score and felt reassured when they needed to keep pushing. Others saw a moderate score and spiraled before their evaluation. Neither reaction serves you.

"Training Risk Estimate" says what the score actually is: a compass for your practice, not a clinical prediction.

What your score is actually telling you

The calculation hasn't changed. If your score was tracking "Low" yesterday, it's still "Low" under the same logic today.

What's worth understanding is how to read it correctly.

A low Training Risk Estimate means your practice performance is tracking well against professional pilot benchmarks. That's genuinely good news — it means you're training in the right range. Keep your cadence.

A moderate score means specific cognitive domains are worth extra attention before your evaluation. The score isn't telling you that you'll fail. It's telling you where to focus. That's exactly the kind of information you want from a training tool.

A high score means those areas need deliberate, prioritized practice before test day. I'd rather you know that now, with weeks to address it, than find out during your actual evaluation. The score is doing its job.

Here's the frame I'd encourage you to hold onto: your Training Risk Estimate is a compass. It points you somewhere. It doesn't tell you what's at the destination.

The VSC and SDC situation — read this carefully

Two subtests — Visual Sequence Comparison (VSC) and Simultaneous Dual Task (SDC) — are intentionally excluded from PilotPrep's Training Risk Estimate proxy calculation. I want to be direct about why, because this matters for how you train.

It comes down to a ceiling effect in the pilot population. Professional pilots as a group score so close to perfect on VSC and SDC that accuracy alone can't meaningfully differentiate performance. Consider: the normative mean accuracy for pilots on Visual Sequence Comparison is 98.35%. A 90% score — which sounds strong in almost any other context — sits more than two standard deviations below that mean. If we included VSC accuracy in the proxy calculation the same way we include other subtests, we'd be flagging the large majority of users as high-risk regardless of their actual cognitive fitness. That's not a useful signal; it's noise.

So we excluded them from the proxy. That's a deliberate statistical decision, not an oversight.

But here's what you need to understand: VSC and SDC absolutely count on the real CogScreen-AE. The official LRPV includes all nine subtests. The bar on these two is genuinely high — near-perfect accuracy and fast reaction times. Just because PilotPrep's composite score doesn't penalize you the same way doesn't mean you can treat these tests as low-stakes in your sessions. The standard is demanding, and knowing that in advance is itself useful preparation.

Why honest feedback is better feedback

This change reflects something I've come to believe pretty firmly about training tools: the most useful feedback is feedback that's clear about what it can and can't tell you.

An AI-informed scoring system that presents itself as more certain than it is doesn't help you train better. It either creates false confidence or unnecessary alarm, depending on which direction the imprecision breaks. Neither helps you show up prepared for your evaluation.

PilotPrep's Training Risk Estimate is built on published aviation neuropsychology research — normative data from pilot populations, not general population averages. The score gives you a real-time, evidence-grounded signal about where you stand relative to professional pilot benchmarks. That's a meaningful thing to know.

But it's a training signal. The only score that matters for your medical certification is the one produced by a licensed neuropsychologist on the official CogScreen-AE. Be clear about what each number is telling you, and you'll be in a much better position to act on it.

The practical bottom line

Nothing about your scores has changed. What changed is the label, and the label now says what the score has always been.

Use your Training Risk Estimate to direct your practice sessions, not to predict your exam outcome. Pay close attention to VSC and SDC even though they sit outside the composite calculation — the real exam holds you to a near-perfect standard on both. And if your score is pointing you toward a specific area, take that seriously. That's the tool working as intended.
