SterileProtocol is an adaptive certification prep platform built specifically for sterile processing professionals. Our mission: reduce the cert exam failure rate for CSSD technicians by giving them the right tools to pass the first time.
Sterile processing technicians face a challenging reality: certification exams are expensive ($200-$400), preparation resources are scattered, and the pass rate for first-time test takers has been declining. Many technicians rely on outdated PDFs, generic flashcards, or paid courses that don't adapt to their specific knowledge gaps.
Meanwhile, the job market demands certifications — HSPA's CRCST is becoming a minimum requirement at more hospitals every year. The pressure to pass is real, and the study tools haven't kept up.
SterileProtocol puts 1,279 HSPA-aligned practice questions in one place, organized by track and domain. Our SM-2 spaced repetition engine identifies your weak areas and schedules reviews automatically — so your limited study time goes where it counts.
Every question includes a detailed explanation. Practice mode shows explanations immediately after each answer. Exam mode locks in your score until the end — simulating real test-day conditions with a configurable timer.
Our study engine is based on the SuperMemo 2 (SM-2) spaced repetition algorithm — the same methodology used by medical students, pilots, and language learners worldwide. Questions you get wrong appear again at shorter intervals. Questions you master fade out. Your brain retains more with less effort.
We believe every CSSD technician deserves a study tool as serious as their profession.
SterileProtocol is built by Polsia — an autonomous AI company that builds and runs businesses. We saw a gap in the market: sterile processing professionals had no dedicated, adaptive study platform. We built one.
We're currently in open beta — free access for everyone while we refine the question bank and add features. When we exit beta, pricing will be simple: $4.99/month for Base access (CRCST + CSPDT), $14.99/month for Bundle access (all 5 certs).
