WHAT IS THE PASS
PROBABILITY SCORE?
The Pass Probability Score (PPS) is a statistical prediction of your likelihood of passing the Praxis exam on your next registered attempt.
PPS is not a confidence score or a feelings indicator. It is derived from your ERS composite, your accuracy trend over the prior 14 days, your session consistency, and your mock exam results — the same dimensions that predict Praxis passage in ETS performance data across Maryland, Georgia, Pennsylvania, and 43 other states.
The Founding Promise
WHEN PPS REACHES 90%, SUSTAINED OVER 7 DAYS WITH 2+ PASSING MOCK EXAMS —
PRAXISPASS DECLARES YOU READY TO BOOK.
THE FOUR GATES TO DECLARATION
Readiness Declaration is not issued on a single good session. It requires four conditions to be met simultaneously.
PPS Reaches 90%
Your Pass Probability Score must reach 90% based on your ERS composite across all five dimensions. The 90% threshold represents the statistical confidence level at which first-attempt passage is the modal outcome.
Sustained for 7 Consecutive Days
PPS must remain at or above 90% for seven consecutive days of active study. A single plateau day resets the clock. This guards against one-session spikes that don't reflect genuine readiness.
Two Passing Mock Exams
You must complete at least two full timed mock simulations and score at or above your state's passing threshold on both. Mock results are 10% of ERS and the final gate for readiness declaration.
Readiness Declaration Issued
When all three conditions are met, PraxisPass issues a Readiness Declaration — the platform's formal statement that you are statistically prepared to sit for your exam. Book it.
PPS VS. GUESSING
Most Praxis candidates book based on feeling ready. PPS replaces that guess.
Without PPS
- ✕Booking based on "I feel ready"
- ✕No signal of readiness trajectory
- ✕55%+ first-attempt failure rate
- ✕$90–$160 registration fee lost
- ✕28-day mandatory retake wait
With PPS
- Booking only when data says you're ready
- 7-day sustained readiness confirmation
- Two passing mock exams required
- Statistical confidence at 90% threshold
- Readiness Declaration — formal clearance to book
COMMON QUESTIONS
Is PPS the same as ERS?
No. ERS is a composite readiness score (0–100) built from five weighted dimensions. PPS is derived from ERS but also factors in your historical accuracy trend, mock results, and consistency streak. You can have a high ERS but a lower PPS if your readiness has been volatile.
What if my PPS never reaches 90%?
PraxisPass will show you exactly which dimension is holding your PPS below threshold and generate a targeted recovery plan. Most candidates hit 90% within 6–8 weeks of consistent daily missions.
Can I book the exam before PPS reaches 90%?
Yes — PraxisPass never prevents you from registering with ETS. The Readiness Declaration is guidance, not a lock. But our data shows that candidates who book before 90% PPS fail at 2.4× the rate of those who wait.
What does the 7-day sustain requirement mean?
You must maintain PPS at or above 90% for seven consecutive active study days. Days where you complete no sessions do not count toward or against the streak — only days with at least one completed mission count.
