Am I Ready for the EPPP? Every Passer We Can Measure Hit One Number First

You are ready to schedule the EPPP when a full-length, timed practice exam (150+ questions in one sitting) comes back at 83% or better. That is not a guess. Across every reported result where we can see the person's prep, that number has separated the people who passed from the people who did not.

In August the pattern held again. Someone reported passing with a scaled score of 570. Before test day they took seven full-length practice exams and peaked at 86%.

Update, September 7: five more reports since the end of August, and one of them retires a sentence in this post. A member who took more than a dozen full-length sims before test day, and never crossed 75%, did not pass. So "nobody who failed had taken a sim" is no longer true. What is true is narrower and holds in both directions: twelve people took a full sim before test day, the eleven who peaked at 83% or better passed, and the one who stayed below the line did not. The chart below now shows that dot. The full case, the updated table of practice peaks against real scores, and what we changed in Prioritize because of the score-report comparison: what practice exam score predicts passing the EPPP?

Update, August 31: three more first-attempt passes came in during the last week of August, a 661, a 600, and a 555, plus one new fail report. The 661 is this post's pattern in its cleanest form: eight full sims inside a seven-day free trial, a 93% peak, one more sim on the morning of the exam. The 600's sim history we cannot see, so it counts in neither direction. The 555 bent the pattern: heavy studying with us in the final thirty-six hours, months of prep elsewhere we cannot see, and zero full-length sims anywhere in our data. So the finding below now carries its qualifier out loud: every passer whose prep we can see hit the number first. The full story of all three, including the one that made us narrow the claim: three first-try passes reported in one week. And if your own exam is days away instead of weeks: the last week before the EPPP is not for learning new material.

How we collect this, so you can judge it for yourself: we ask every user who sits for the real exam to report back, pass or fail. Twenty-eight people have done that: seventeen passed, eleven did not. These are collected reports, not a pass rate, and they are only the people who wrote in, not everyone who tested. The sample is small and self-selected. I am a clinical psychologist, and I will not dress twenty-eight data points up as a clinical trial. But the split below is stark enough to be worth your afternoon.

The Finding: Above the Line Everyone Passed. Below It, Nobody Has.

I expected to find that the people who failed had scored badly on practice exams. That is not what the data says.

• Eleven passers took at least one full-length, timed practice exam before test day. Every one of them peaked between 83% and 93%.
• Ten of the eleven people who reported failing had not taken a single full-length practice exam before walking into that exam.
• The eleventh had taken more than a dozen, and never crossed 75%.

For most of the fail column the failure mode was never generating a practice score at all. For the one person who did, the score was below the line and said so.

Six other passers had no sim data we can use: three had essentially no platform activity before their exam (two of those reached us by word of mouth), one passed on a fourth attempt using targeted quizzes instead of sims (more on retakers below), one joined a week before the exam and used two minutes, and one, the 555 from the update above, studied hard with us in their final thirty-six hours but took zero full-length sims. So the honest version is: among people we can actually measure, every one who passed had put a number at or above 83 on the board first, and the one person who put a number below it on the board did not pass.

Practice scores also landed in the same neighborhood as real scores. The two people who peaked at 93% scored a 711 and a 661. The people who peaked in the mid-to-high 80s scored between 570 and 630. Seven examples do not make a law, but the practice number was never noise.

The Two People Currently Below the Line

Here is where the data gets useful instead of just flattering.

Two members who joined after failing the EPPP are now prepping for retakes, and both are taking full-length sims. One has taken eight of them over the past month and peaked at 76%. The other has taken two, scoring 78% and then 71%.

Neither has retaken the exam yet. And that is exactly the point: the readiness line is currently telling both of them "not yet," while a retake still costs nothing but time. The person with eight sims has put in about 40 hours. Effort is not the missing piece. Effort without a rising accuracy number is just volume, and volume was never what separated these groups.

If your own sims are sitting in the 70s, that is not a verdict on you. It is a signal doing its job early enough to act on. Low-70s sims almost always mean two or three specific domains are dragging the whole score down. Find them, drill them until your accuracy climbs, then take another full sim and let the number tell you when it is time. That playbook is the same one in what to do after failing the EPPP, and it works just as well before a first attempt.

About "Nobody Who Prepped With Us Has Failed"

I have written that line before. At twenty-eight results it no longer holds as written: one member prepped with us for six weeks and did not pass. What still holds is that ten of the eleven fail reports came from people who had no full-length sim with us before test day, and most of them had no time with us at all. One failed seven months before joining. Another signed up two days after testing.

But I want to be straight about what that does and does not mean, because it is the kind of stat that sounds like a guarantee and is not one. People who find a structured prep tool months before their exam are already different from people who cram and hope. Some of that gap is the method. Some of it is who chooses the method. I cannot separate those two with twenty-eight self-reported results, and anyone who tells you they can is selling something.

What I will stand behind is narrower and more useful: measure yourself before you commit to a test date. That single behavior is the cleanest difference between the two groups in this data.

What "Ready" Actually Looked Like

Two passes from earlier in August are almost a how-to on their own. Details are kept vague on purpose; we never publish anything that could identify someone from their data.

One took four full sims over about eleven weeks, peaked at 88%, and scored a 600. The other took seven sims, climbed from 73% to 86% across roughly ten weeks, and scored the 570 that opened this post.

Notice what both did:

1. Full-length sims, plural. Not topic quizzes standing in for the real thing. The four-hour version, where question 140 happens to your brain. Our passers took between two and thirteen.
2. Accuracy before volume. Passers drilled until they stopped missing, then confirmed it with a sim. Grinding hundreds of questions at 65% correct is rehearsing confusion.
3. They booked test day off the number, not the calendar. The sim score made the scheduling decision.

One nuance worth knowing: your best sim is the signal, not necessarily your last one. One passer peaked at 92%, dropped to 77% four days before the exam, and passed comfortably anyway. If your scores dip late, read this before you panic-reschedule.

How Do I Know If I Am Ready for the EPPP?

Turn the question into arithmetic. A full sim takes about four hours. If your exam is eight weeks out, you have maybe six or seven realistic chances to run one. So take one this week, timed, in one sitting, and score it honestly.

• 83% or better: you are in the range every passer we can measure occupied. Schedule with confidence, and keep taking a sim every week or two, because readiness is something you hold until test day, not a badge you earn once.
• 79% to 82%: close, and in a range where we have no reported results either way. I would drill weak domains for a week or two and clear 83 before booking.
• 78% or below: this is where the one measured fail sat, and where both of our earlier retakers sat before they started climbing. Diagnose the weak domains, repair them, retest. Do not book yet.
• No sim yet: you share that with ten of the eleven people in this data who did not pass. Fix that this week, before it costs you a $692 exam fee. (One recent passer is the exception, and they arrived with months of prep elsewhere and an exam the next day. If that is not you, take the sim.)

Can Retakers Skip Full-Length Sims?

Sometimes. One passer on her fourth attempt took zero sims and used targeted quizzes to close specific content gaps, because real exam attempts had already given her the four-hour-room experience. If you have sat for the real thing before, prep can look more like targeted repair than stamina training; more in the best EPPP prep for retakers. For first-timers, skipping sims is still the most common pattern in our fail column, and the one person who did not skip them was below the line when they sat.

Find Your Number Before the Exam Finds It for You

Every result in this post came from someone generous enough to report back, pass or fail. If that is you, write in; the next person reads their runway off your data point. You can hear passers in their own words in EPPP success stories.

And if you have never taken a full-length, timed EPPP practice exam, that is the one thing to change this week. thePsychology.ai includes full-length simulated exams and a readiness meter that tracks your best score against the 83% line. It is free for a week, which is exactly long enough to take one sim and replace "am I ready?" with a number.
